Astronomical Sketching values & Monthly Contest
      #2437408 - 06/03/08 03:04 PM

With Erika's agreement these comments on astronomical sketching have been copied as a separate thread.

An entry to the May astronomical sketching contest was rejected. It showed four sketches of solar prominences made at 30 minute intervals. The occasion was unique because Solar Forum members had agreed to make time synchronised observations to crosscheck the accuracy of different observing techniques. Many prominences change so fast that comparison of sketches and images made only minutes apart usually tells little of the accuracy of the former.

It seemed a wonderful opportunity to allow other astronomers to judge the accuracy, validity and therefore credibility of astronomical sketching as a worthwhile complement to electronic imaging. Not because the sketches were especially accurate, there were some glaring errors! But because the subject of accuracy was directly addressed.

In many ways we are sometimes seen as poor relations and not taken too seriously. It seemed an opportunity to let viewers to see and, importantly, vote on, what we sketchers can achieve - and what we fail to achieve - in accurately portraying astronomical objects. That was why it was submitted.

To allow the judgement of accuracy (and the inaccuracies!), small comparison photographs by Pete Lawrence were put at the base. For a fast changing sun there is really no other way to demonstrate and judge accuracy. I said that Pete had independently made the images. I could have added that the sketches were published on CN an hour or so before any images - but that seemed an unnecessary and perhaps distasteful protest of honesty.

Erika, as Moderator, and I have had wholly friendly exchanges about the disallowal and she has consulted other Moderators and Administartors. I’m very grateful indeed for her patience and forbearance and that the issues were treated seriously and that time was given to them. Sketchers - We cannot wish for a better moderator.

This note is not in any way a questionings or criticism of the collective judgement to reject. Not at all. I hope that the above statements are seen as purely factual, that’s the intention.


The discussions have raised issues about the nature of astronomical sketching as we practice it, its credibility and how it might best be presented to and judged by other astronomers. I hope that these issues can be reasonably mentioned and discussed in this Forum.


Astronomical sketching has a long and honourable history with Galileo and the 3rd Earl of Rosse being only two of many exemplars. The tradition has been predominantly one of careful and meticulous scientific striving for objectivity and accuracy at the eyepiece.

The essence of science is that it is based on dispassionate observation and just as important, that others are able to judge independently the accuracy of those observations. In the 21st Century we have excellent means to do that via simultaneous digital imaging. Not to use such comparisons when we present some aspects our work is an omission. It could be interpreted that we are somehow afraid to do so, that we are not confident of our drawings, that we do not take accuracy seriously. That reduces our credibility and devalues our efforts, devalues astronomical sketching.

Such comparisons are permitted in ordinary postings within the Forum. Of course. But that is not the issue. When in Contests we place our work for judgement against other forums’ digital images or even other sketches in our own, why do we seem to put a low value on accuracy as a judgement criterion? Why do we not include, where appropriate and necessary, small comparisons that will allow voters to see that we care about accuracy and are prepared to stand up and be judged on it? The comparisons will not always reflect well on our sketchwork, but they will tell of our intentions and honesty.


All the above assumes that we in the Forum, like Galileo and Rosse and others, continue to regard astronomical sketching primarily as a figurative, objective and science, as well as art, based pursuit.

In her careful comments on the Contest entry Erika has said:

“Astronomical sketching comes in many forms. There is realism, impressionism, and astronomical art, and dare I say everything in between. Impressionism created at the eyepiece can be just as effective because it invokes the "feel" of the object as seen in the observer's eyes. Of course those that do realism strive for the accuracy of the object itself. Some create sketches digitally based on their pencil sketches and notes.”

“And with regards to the contest, clearly impressionism would be just as valid as realism if it were an observation sketch and is the object as seen through the observer's eyes.”

“So with this in mind, validity for a sketcher's work should be on their work alone”

With due respect to Erika (and honestly Erika these comments are a discourse about the nature of astronomical sketching not criticism of individuals nor a criticism of forum Moderation), this interpretation is a relativist one. It sets little or no more store on objectivity, accuracy and external validation than does fantasy and space art. By those tenets ‘all is permitted’ and if all things are not equally ‘valid’ they are certainly much of a muchness and subject to individual whims.

How is another astronomer when seeing our sketches, particularly solar ones, to know whether it is a genuine attempt to figuratively record nature or a work of fiction or emotive interpretation when these are our proclaimed values? How can they take us seriously?

Of course other interpretations of astronomical subjects have a place in art. But in all humility, that place has to be well defined and viewers need to know where they, the artist and the forum stand when work is offered.

We are an astronomical community. Astronomical sketching is astronomy. Astronomy is one of the physical sciences. Science is based on careful and dispassionate observation of nature - - Not fantasy, not space art, not impressionist or emotive interpretations. And specifying that they be made at an eyepiece does not change that. To treat astronomical sketching as other than objective striving for accurate portrayal and allowing validation by others against images is to devalue it, devalue astronomy and deny the long heritage of scientific drawing and recording that we belong to and are proud of.

To ask therefore what values we have for our astronomical sketching and contests - to ask what Galileo and the Earl of Rosse would think of us seem legitimate questions that we be should be permitted to put to ourselves and discuss within the Forum.

Les --

Very interesting post. Personally, I attempt to make my sketches as accurate as possible (accurate to what I see, not necessarily accurate to what is out there). My interest in sketching started out in deep sky, where photographs (due to their vastly increased gain coupled with their vastly decreased dynamic range) are a particularly poor representation of what an individual might see through the eyepiece.

Now that I've gotten involved in solar as well, I'm very interested in the juxtaposition of sketches and images as they're much more similar than with deep sky. So I agree with all your comments on accuracy, science and objectivism.

But I also understand that CloudyNights is a very inclusive community. There are folks here of a much more artistic nature than I. And there are folks who are much more scientifically motivated than I am (I don't even record the whole limb, which clearly devalues my sketches in terms of a record of the sun's ever-changing state).

I can't help but notice that the imagers revel in a multiplicity of imaging contests. (There's even still a film one going. How last century! ) But I've also noticed that the sketching contest is not overly subscribed (it's not like we're getting 10 entries month-in-month-out). I wonder how many we'd need to get to warrant splitting into a scientific/observational contest and an artistic/impressionist contest? (Or some other taxonomy if that's not the right one.)

Les - first of all, let me say that your solar sketches are awesome. You have given me an idea of what to do with the 4.5" mirror currently sitting in a drawer, which is to build it into a solar scope.

Secondly, I am a complete novice at sketching, so my comments can be taken for what they are worth. The relevant question is, why do I sketch? Currently I am working on lunar features. I do as much as I can at the eyepiece, then take it indoors to fill in shadows, smooth out rough marks, etc. Is this dishonest? No. It would be if I were consulting an atlas, or detailed photos, to complete my drawing. I sketch for no one but myself, to sharpen my attention to detail and my observing eye.

When you categorically declare:

I think you are saying more about your own approach to sketching than you are about sketching itself.

I'm sorry, I'm not good enough at sketching to do "real" science, by your definition. My scope is too small; my technique too ragged. In a sense, you're out of my league. But I'm not going to stop, even if you think I'm denigrating the heritage of Galileo and Rosse.

I have to wonder, why do you sketch, if scientific accuracy is the be-all and end-all? Just take a picture. But I'm guessing there's more to it than just science, admit it!

Les,

Interesting post!

Personally I don't rate images any more objective than sketches.

Running a series of avi's through Registax, then tweaking a number of parameters to get a 'satifying' result, can be spectacular, but I don't call it objective.

As for my sketching values, here are some:

1) the real time 'live' experience under the stars,
2) a connection with the astronomical target,
3) a more profound and growing impression of the eyepiece view thanks to the sketching process,
4) producing an eyepiece view that tries to represent an impression, a souvenir from a visit to far places, that can be saved and shared with other stargazers (and novices, so that they learn what to expect to see).

Personally, I sketch my astronomical viewing to show what could be seen. Sometimes it looks pretty, sometimes and at some objects it remains a raw sketch.

In my eyes sketching is most valuable, if huge differences in luminancy have to be covered. This happens at the H-alpha-sun and comets regularely.

You my look at my webpage to see some of my results. The page is in german, but easy navigable.

Welcome to CloudyNights, Uwe!

You've got some nice solar sketches on your website. I also enjoyed your 17P/Holmes sketches (that was the first object I ever sketched).

Cheers,

Personally I try to make my sketches as accurate as possible, so I keep on placing my stars on the paper until the seem to be in the perfect position where they are in the EP. But that does not make me think, that accuracy should be the most important aspect of sketching. I think sketching is rather about what you see or what you THINK you see in the EP, and how you FEEL an object. An impression. And I don't mind if someone only pays attention to the subject of the sketch and not the stars around it.

On the other hand, sometimes a fainter object looks more luminous on my sketches than a brighter. That does not mean that I sketch luminosity inaccurately. It only means that on that day the NELM was probably better, so even an object that is catalogued as faint could be seen brighter.

I would be sad if there would be an elitism in sketching and I could watch sketches on these forums that were pre-judged by some jury, and classified as accurate enough to be posted. That would be probably my last day on these forums. Sketching is about diversity in my opinion.

Just my 2c.

Interesting topic...The short comment is, I sketch what I see, however.......

Unless it's sketched from the EP, I consider it art, if it is sketched from the EP I consider it a "moment in time" and nothing more...I also don't think they are scientific in nature, however, understanding the science behind what you're seeing can make it more enjoyable...

What could we as sketchers actually see, or more so, discover that isn't already known?...We are enthusiasts and some are also archivists, but I don't connect it to science...I am definitely open to how it could be, I understand Galileo's were, but I feel we need to concede to higher technology in this case...

I'm also not sure what everyone does here to make their living, but I don't remember seeing solar researcher/scientist under too many names(spaceydee is one of the exception I think), so that being typed, the reality is, to me, it's a hobby and our sketches are the way we've chosen to document/collect and show it off...

People by nature like to share what makes them feel good and it makes us feel good when we get that "ooh" "ahh" feeling when the viewing is just right and we hope to convey that to others thru our sketches...

Sidenote, if any scientist is using my sketches for any serious research, he/she needs their credentials examined! LOL

accuracy in my sketches depends on the subject sketched;

- planets as accurate as possible (i put a lot of time in just observing and trying to exclude things i *think* i can see), so sometimes the sketch looks rather nice and detailed, sometimes it looks pretty undetailed.

- for deepsky (which i do a lot less), i don't put much effort in trying to 'copy' the whole starfield, so usually there are lacking (many) stars in the skecth. i focus my attention on the deepsky object itself, whatever it is, and treat it like a planet-sketch.

- moonsketching is a whole different story for me. i actually enjoy sketching moonscapes the most, and give myself much more freedom with the sketch because it's loaded with details. moonsketching approaches real drawing the most i feel, which i like. so it doesn't matter to me if there's a small crater lacking here or there, or displaced, it's about enjoying the drawing itself

Sketch Responsibly

My goal is accuracy. I've never been impressed by renderings which are computer enhanced or created, or by drawings which are better suited to the astro-art forum.

I don't sketch at all but I value the sketches posted to the solar forum more than the photos as I find they often show the details I see at the EP, or even details I could have seen if I had been more patient. Looking at an accurate sketch allows me to practice my abilities as an observer. When I see sketches of the sun from the turn of the century I find they could see pretty much what I can see. I find that comforting somehow.

I would encourage any would be sketchers to be as realistic as posible at the EP. If you also like to make art that is great too, but to me the skills are quite different.

Les, the series of images you submitted to the contest were amazing. I was at work that day but I felt like I got a whole day of observing in. Thank you for your work!

>>>>I would encourage any would be sketchers to be as realistic as posible at the EP. If you also like to make art that is great too, but to me the skills are quite different.

I wish I had that choice, although I can see great improvements in my sketches, I don't think anyone would confuse them with art...

I too think, when it comes to enthusiast imagers/sketchers, that sketchers have the advantage of using their eye(sure it can also be a limiter) but the eye adjusts and auto-focuses itself the longer it looks at something allowing one to see more than a camera!...Imagers also require a tracking system which to me is a limiter as may actually keep the object, or other details out of the sweet spot never to be seen...I make sure each feature I sketch goes thru most of my field of view so I can capture those subtleties...

But of course there are days like today when the weather just makes it uncomfortable and takes much of the fun out of it causing me to rush...The archivist side of me will not allow me to not view and sketch everyday if possible, I actually feel guilty, I NEED HELP!

Happy SUNday to you all!!!!!!

To all

A very interesting discussion- I am impressed to see all the conjecture here from many others and I would encourage it, especially to those who say they do not do sketching although with due respect to the rules set by Erika to comply with posting artworks in the “Sketching Forum” as she is most generous and fair about this. I am especially interested as to what Les Cowley is addressing here and would refer to Les' quoted words below here as it would welcome artists such as myself who defy the categorical description >

“And with regards to the contest, clearly impressionism would be just as valid as realism if it were an observation sketch and is the object as seen through the observer's eyes.”

“So with this in mind, validity for a sketcher's work should be on their work alone”

I am glad to see that Les is accepting that impressionistic art can validate the scientific method. These comments seemed to have created a stir with the perceived process of the scientist and the scientific methods they lay down as “laws”. One can see from the discussion that others are questioning art vs science here. I can see that the two mediums are not in reciprocating concurrence as several expressed their disdain for art.

As many know that I am now complying with the forums and placing my art work into the Astro Art Forum rather than the Sketching Forum as I want to comply with Erika's set rules here but which I was not originally aware of. I merely saw the Forum labeled “Sketching” one day about a month ago and thought I could send my images in because several people that I am acquainted with suggested that I send them to the “Sketching” forum. As many know now, I crashed into that sketching forum by plastering several of my “accurate” solar sketches into the daily bulletins strewn along randomly in answer to several others posts albeit with my hand in the sketch doing the sketch and some of them contained ambient abstract images on the side- ie; a wild prominence emanating from a sunspot that I evoked a passionate impressionistic abstract image of below the actual accurate full disk image of the sun that Erika praised as one of the best full disk renderings sketched of the sun that she has seen yet. I don’t mean to brag here, but as many know these have been featured many times in two of the most highly respected daily NASA reporting sites of current sky imaging. Astronomy Picture of the Day once (Nov 17th, 2006) and that is once enough as I believe I am the only artist to have ever been featured there at that time. I am most honored about that as they usually run only Hubble Space Telescope Photos, NASA space probe images and occasionally an amateur astronomers photograph but never hand sketched art. I am now told that photography has oversaturated the internet and art (and scientific art) is once again respected. I would like to think that I helped a little to inspire others to the artistic process.

Then since October 14th 2006 perhaps a dozen times to Spaceweather.com to their front page and that started as many know, because I was influenced by seeing Erika’s sketch that day in that site. As I also told later, it was Les’ sketch I saw first that day, but Erika’s did something for me- It was the useful scratched side-notes that she placed at the bottom of her sketch that caught my attention. Herein lies the irony of all this. Yes I know my hand in the sketch bothers some people but I have found that it gets the attention of the ones who are least likely to do “art” and that I am told now inspires them to possibly “try their hand” at it for the first time. “Artistic process can teach the scientific method” as they say. I am not telling artists anything here because they already know this. Artists have been begged to entertain the masses for millenniums. And so they do. And so, as it goes, life imitates art, as they say.

But let me not stray from the issue at hand here, so to speak. I was not originally aware of the rules in the “Sketching Forum” until Erika and Charlie Hien wrote to me personally. I was at first perplexed about this as I was honestly and truly making dire efforts to record the solar prominences and surface features as accurately as possible as an observational astronomer. I did not understand until I was told that “re-sketching them later into lavish pastel images” or copying my own work from preliminary pencil sketches was not allowed as it risks embellishing onto the original scientifically accurate sketch. I understand that now and let me tell you, artists do have a passion for, [read obsession for] embellishing subliminal imagery. *Read about Da Vinci (also refer to the book: Art & Physics below as the historians concur now that Isaac Newton was influenced in his science from Da Vinci’s art.) I now understand that these scientific sketches must be done real time and simultaneously from the EP (eyepiece) and not later reworked as that first impressionistic abstract that I did hours later to be shown in Spaceweather.com in October 14th ~ 16th 2006. Hence, I did not read the rules before originally posting here. But in Les’ words quoted above he seems to be reconciling with impressionistic artists now. I felt good about that but realize that Erika moderates the site and we must respect her for that.

I further made the mistake of “bad timing”, literally in my recent work of that large solar prominence on May 14th as I miss-figured my UT time recorded on the page of the work (see in my gallery.) Erika straightened my clock out on that one and I thank her respectively for that. I also copied Les Cowley’s Tilting Sun into the sketch for the first time; by hand drawing it to what I thought was accurate. As I rushed the first time to do this, I made the mistake of setting the horizons flipped from east to west in the program to comply with the reverse image in my Coronado SolarMax refractor but I sketched the arrows indicating rotation in the wrong direction on the globe of the sun. A scientific error on my part? The casual observer of this art piece, I was later told could have cared less as one noted to me, “Mark, your works are so appreciated because they look better than real photographs of the sun or even others reported real live observations! Another said expounding further, “When I look at your art of the sun Mark, I feel that I am looking at the real thing through the telescope”. I guess many artists would take that as a compliment. Yet I tell everyone that I want to get away from “realism”. Serious artists really want to become abstract expressionists. But as an astronomer, I want to report the facts too, so I try to appease all sides. Unfortunately in this recent rendering, I very accurately depicted the large solar prominence on May 14th 2008 to the way it actually appeared in the eyepiece, but worked it later from copying it from my pencil sketch albeit near an exact copy, it was a second generation done later and not done at the time of actual observation. Yet I added so much in other ambient art (the largest hand I ever sketched into my work) and mistaken text info (wrong UT time and mistakenly reversed arrows on the Tilting Sun graphic) that I may have lost the scientific worlds respect for my accurate scientific artwork of the solar image at the center of the work.

Do I understand this right in what Les reiterates above in his quotes? Les [is] saying that impressionism should now be allowed as technically valid scientific documentation art as impressionistic artwork is understood as accurate because it is the way the artist "feels" it to be at the time he or she creates the work from direct observation? Sounds very democratic to me, but I made the mistake of not reading or understanding the rules and I now understand that my works are strictly and only “art” according to this sketching forum even though I made the solar images very accurate to what I observed by later copying them in color pastels from my own original preliminary pencil sketches. Erika has explained this to me and I understand what she is saying now. Every time we duplicate something from the original it is at risk for degradation or embellishment, as would sketching from a dated photo of the sun opposed to live real time observation as the sun is so dynamic, that it changes constantly. This applies to many things in life; even photographs recopied become blurred and degraded in resolution with repeated generation of production. Go to a Xerox copier right now and make a copy from your best photographic prints. You’ll see that they are terribly lacking of integrity in the new Xerox copy. This varies of course with the medium and equipment used. However, as stated further in Les’ post above and I believe Stephen Ames concurs with this below, “artists eyes can capture things that the camera cannot at that moment of observation. Many people do not understand this statement and especially some astro photo imaging astronomers who would say “why waste your time drawing when you could easily just take an accurate picture?” We are now talking about apples and oranges. Some photographers do not understand the artistic process as they have never been through it and especially at the eyepiece of a telescope. *Please refer to Ferris’ Seeing in the Dark film aired on PBS last Sept 2007 which shows Stephen J O’Meara sketching at the EP and his delicately rendered images he sketched as discovered about Saturn’s rings before the Voyager photographs captured these images.

In turn much of the general public thinks that all pictures are worth a thousand words. These cliché phrases have always concerned me as to how we perceive what is real and what is merely an implied emotion in life or may I say, “further blurred in the use of and the laws of the language”. But do you see “pictures or rather photographs” being auctioned for a hundred million dollars at Christy’s or Sotheby’s? There is a relative reason for this. Les mentioned “emotive feelings” that are rendered in the artists work. I would like to address that but it is a difficult area to discuss when we talk of “art” (artistic process) vs. “science” (scientific method). I could go on here all day because I have been through this repeatedly with respect to local astronomers in my region in the Portland area. I have also just won another photography award that I do not have much regard for. It is a photograph that I took of a tree in the Oregon desert in 1994 (see my gallery)>
http://www.cloudynights.com/photopost/showgallery.php?ppuser=37924&cat=500


with circumpolar star trials turning in time exposure overhead that appeared in the December 1994 Astronomy magazine as full page. I only wish now that I had painted the picture rather than taken it as a photograph. In actuality another unknown bystander literally “painted the tree with red light” while I was away from the camera. The photo teaches something as much as it evokes a passionate artistic feel. Someone once told me that they thought it would be what Van Gogh would do with a camera, were he alive today.

And speaking of cameras, I did not know that the work which was removed from the sketching contest was Les’ multiple images that included photographs at the bottom taken by another astronomer to compare accuracy of images with. I knew what Les was doing here and I truly appreciated that work that he submitted it with the photographs. Is this in fact the work that was removed? Again, I could go on here forever about comparing art and photography. This is possibly yet another discussion for another forum as I am disappointed with some of the use of photography these days. I am talking of course of the overuse of Photoshop to the point of rendering images as falsely manipulated. As an astronomer, I get tired of friends who want to discuss supposed UFO sightings later shown in Internet screens with fuzzy artificial photo images who have never observed the sky at all for themselves. They cannot even find Ursa Major in the northern hemisphere, yet alone Ursa Minor. How would they expect to find in the sky a false image of an alien ship that they believe is real on an internet or TV screen? Hence I will coin a new line- Image was everything at one time- “Today, image is anything” – M 2008

Finally I wanted to address the final artistic product as I have been likely to place my superfluous left hand into the sketch as my “signature”. Is that wrong? Some friends tell me that it is “too heavy handed”.

I like to reflect on a historical story about art: A similar argument that occurred when Claude Monet painted his inception of the impressionistic movement with the work that he titled "Impression Sunrise". The French art world came apart and they were livid not only with his title but also implied style of "sketchy painting" that did not comply with the conventional and more traditionally excepted school of thought in the art world then; to become known as a style called impressionism.

Now with that said could I ask that my hand in the lower part of the sketch be known as my "signature" and thus understood as not part of the sketch of the solar activity that I render as accurate? It is difficult to get a 20” X 24” sheet of pastel paper filled in outside as a finished work at the eyepiece, so this also comes down to a matter of trust from my contemporaries in the amateur and professional astronomy world alike. Can I request this privilege?

Where do we draw the line here, and what is really at hand, so to speak? Is it art or is it science or is it all of the above?

Respectfully,
Mark (*I edited/corrected my mispells today - June 9 '08)

PS; I would highly recommend to all to see this review of a respected book written by a doctor, titled Art & Physics – Parallel Visions in Space, Time & Light - by Leonard Shlain>

... with Erika's set rules..





Let me clarify this statement, please. These are not my set of rules, but rather guidelines as discussed and agreed upon by the administrators and moderators of Cloudy Nights. My personal methods/thoughts/styles of sketching do not enter into this what so ever and this is not "my" sketching forum.

As stated before, we all have our reasons for sketching so we need to be respectful of all styles here.

The only stipulation is that sketches rendered "after the fact" are considered "Astro Art".

Mark, your eyepiece sketches are most welcome in the sketching forum as stated before. Using your eyepiece sketches as inspiration for abstract art later after the fact makes the recreated piece Astro Art so needs to be posted in the appropriate forum.

The camera images from Pete were not allowed in the contest because we (the other admin and moderators of CN) agreed that the entries must consist solely of the entrants work and not to include works of others.

Les was given the option to crop out Pete's images so the entry would be his sketches alone. He chose to have his entry removed instead.

I felt that I had already said quite enough in the first posting . However I must correct words that Mark has wrongly attributed to me:

"And with regards to the contest, clearly impressionism would be just as valid as realism if it were an observation sketch and is the object as seen through the observer's eyes.”

“So with this in mind, validity for a sketcher's work should be on their work alone”

I did *not* say that - Erika did

"I am glad to see that Les is accepting that impressionistic art can validate the scientific method...."

Over my dead body!

Umm, I don't want to hurt anybody's feelings, but then 99% of the photographic images are also "astro art":

1. They are usually NOT a single, long-exposition shot, therefore they are altered (stacked) after taking the images.
2. They usually also use false colours to make objects look nicer.

If only the "on-field" sketches can be regarded as accurate captures of the moment, then only single, long-exposition, not altered, true colour astro-photos should be allowed to participate and all the others should be eliminated. but then this would be the most boring competition.

Sorry that I add my thoughts as a newbie..

There has been a long-running debate in historic building conservation about modern interventions. While it would be nice to leave all buildings in their historic state (repairing like-with-like, where needed), it is well-known that buildings which are poorly adapted to modern use tend to be left to decay. The conservation movement has come to accept modern interventions with a few caveats:

  • they must not intrude on the features which make the building historically important,
  • it must be immediately apparent that they are not part of the original fabric,
  • and where possible they should be reversible.

    I would argue that guidelines similar to these (well, the first two anyway) might also work well for us. Les' comparison images could be allowed as long as the central sketch was not impinged upon, and as long as the comparison images were obviouslly an after-the-fact intervention (supported perhaps by boxing them, or further annotating them, or color vs black-and-white or some other visual separation).

    Similarly, Mark's hand could be allowed as long as it didn't impinge upon his at-the-eyepiece portions, and as long as the hand was obvioulsy not part of the scientific sketch. The first might require a bit more distance or detachment than he's used to, but the second seems pretty obvious to start with.

    These guidelines might be seen as more of a slippery slope, but as starquake points out our current guidelines are a bit slippery as well. (Certainly the Tilting Sun diagrams in my solar sketches are done after-the-fact, as are the E/N annotations in my deepsky sketches.)

    Les

    My most sincere apologies. I am truly sorry that I took those quotes out of context in mistaken identity. I thought those were your words. Now that I know they are Erika's, I am possibly comforted somewhat, as I was afraid that I might be asked to leave the forum soon for relegating myself to only doing artworks in the art forum. In those quoted words I began to think that you were more liberal in acceptance of impressionistic artwork than I. It was actually your sketch first in Spaceweather.com that caught me to then see Erika's in their site. So I owe much of this to the both of you. I cannot thank you both enough.

    I was also wanting to hear others thoughts about the book Art & Physics as it attributes much in reverence in the history books for artists initiating and compelling scientific discovery more than the scientists. I could not help agreeing with some of those statements in Shlain's book, as I reflected on so many people who wrote me in email after seeing my works in Spaceweather and Astro Pic of the Day, to express that they never thought of doing artwork from live observation in a telescope because they thought that it was a requirement of only allowing professional artists at NASA to do this. One guy said that his girlfriend was never interested to observing through his telescope, until after seeing my work in the NASA sites, she literally ran to the art store to buy pastel chalks and demanded that her boyfriend allow her to observe through the telescope for the first time because she wanted to duplicate what I did.

    Is this not the artistic process inspiring the scientific method?

    respectfully,
    -Mark

    PS: I also see Jeff Young now suggesting that my hand be allowed into the work. Just when I planned to remove it so as to qualify my sketching as more to the technical tradition and to be allowed here in the sketching forum.

    Now I am confused. I feel like quoting Hillary. What does Mark want? What does he want? . . .

    Only to inspire others to learn from art that is the 'Shock of the New' that would in turn inspire the science - Robert Hughes; the art critics titled book of years past. Another literature to learn from that I must recommend to any interested artists/scientists.

    So, I am confused. Can I submit a sketch to the monthly contest which was sketched from an image projected on to a monitor, yet from the telescope, but one which I have not actually looked though the eyepiece at, from my telescope? What about eyepiece projections sketched at the eyepiece but finished, with north/south/eyepiece orientation later? Thanks, Jane
