Besides Mars, I was also sketching few Messiers last night. Here is the first one, M11. This  time I kept separately low power and high power sketches, not trying to combine them into one. Both offered beautiful views. At low power, nearby 4 bright stars west from M11 were showing very vivid colors, one reddish, one yellow/orange, and two blue stars. There was some haze going in and out. I could see how it sometimes washed out the colors. In clear moments, the colors were very strong.

 

M11 was nothing but a small comet like nebular patch around brighter star. It became more alive at 62x, there were more stars and the whole surface was grainy:

Very nice indeed!!  Wonderful wide field sketch that captures what you saw at the eyepiece beautifully!  Messier 11 is one of the truly splendid star clusters on the list.

Regards,

Randolph

Very enjoyable to see it under both magnifications!

Alexander,

 

It is impressive at any magnification or aperture.

Very fine sketching.

 

Frank :)

Here is another Messier, this time from yesterday's night. Final image was made directly out of the sketch made by eyepiece, not redrawing the stars in computer. That's why it made it before two more Messier objects from previous night. Sky was quite bad, haze and thin clouds. Therefor I picked up M29 as it should not be that affected by those conditions:

Here is the second Messier from September 5 (one more is still coming). Originally I wanted to sketch wide view of M31. However under my light polluted sky, it was rather washed out. At power of 13x, I was able to notice M32 and M110 with quite some difficulties. The view at 44x was more dramatic, now both M32 and M110 were clearly visible including their shapes. Still no dark lines, for that I will have to go to darker places:

Sasa, really your FOA60 telescope should be the "pump", how is it possible that with such a small aperture you can obtain such good results? I am totally "anoyed" .. ha, ha!
his drawings are fantastic ..
Thanks
Paul

Thanks to all likes. Paul, FOA60 is not my first 60mm refractor. I have 63mm Telementor since 2013, it is my most used telescope and I made numerous observing sessions with this. So I'm not surprised by the capabilities of FOA60. What surprises me is that I'm able to do with such small apertures reasonable DSO work also from our light polluted backyard. By reasonable I mean interested enough to keep me going out and observe with 60mm refractors even after 5 years. I think this is because I'm still in learning phase, discovering and noticing new things as my observing skills improve. With FOA60, it is about colors, enjoying targets with beautiful star fields.

 

Also don't take the sketches too seriously. I'm not trying to show the targets how they appear in the eyepiece, it would be too boring as many objects would be too faint (like M32 or M110). What I'm trying is to record the observed details  while preserving brightness proportions. This usually means drawing the objects brighter than they appear in the eyepiece. In particular this is the case for most of my galaxy and nebula sketches.

In reference to the above post, that explains how detailed your Andromeda sketch is. Very nice work!

And here is the last Messier from September 5. As I was in Scutum area, I paid a short visit to M26 as well. It was not that beautiful as M11 and I spent much less time in sketching it (there were definitely much more stars in the FOV). Cluster itself was just faint milky patch around medium bright star. Few more stars were popping in and out with averted vision:

Actually, there were not that many details. Just bright stellar nucleus, around some brighter elliptical core and then long faint body, forming more a line than ellipse. All that with a little bit of mottling. That's all, no dark lines, bright patches like NGC206 (5 years ago I was trying really hard to spot it in 63mm Telementor, I think I succeeded but it was a threshold object in this telescope). I hope to come back to M31 under dark skies.

Nope. Only M29 is an authentic sketch made directly by hand at the eyepiece. I just use computer to invert it and add star colors.

For other sketches, I used computer to plot stars (based on the sketches made at the eyepiece, like M29), then I printed them, added by hand the nebular parts and then I used computer again to add colors and invert the image.

Here is an update on M31. I was observing it again under better conditions. Still from our backyard but this time I could easily see M32 and M110 already at 13x which was not the case of the first night. At 44x I saw few more details. Southern edge of bright central core was ending more sharply, I guess there is some dark line. Also a little bit further away, there was another brighter line (arm?). Unfortunately, I could not see prominent dark lines north of the core.

 

I was checking sketches on web. I found only one with this brighter edge at south and I found no one on web with the further southern arm, except drawing from O'Meara in his Messier book. Definitely I'm looking forward trying this nearby galaxy under dark side:

Here is the second Messier from September 8. Globular cluster M72. It was quite a difficult target for 60mm refractor. It took me about 5 minutes before I even started to see it at 13x. It was almost invisible. Higher powers worked better. I spent quite some time scrutinizing the cluster and surroundings at 104x, not an easy task with a planetary eyepiece with almost zero distance of exit pupil, like Pentax XO5. I could not see too much details, slightly brighter core was a little bit mottled, my guess was that it  might  be  of triangular shape (not really sure here, still I put it on the sketch). I noticed few faint stars in the vicinity of cluster but they don't seem to belong to it as brightest stars in M72 reach 14.1 visual magnitude while recorded stars are not below V~13.0.

And one more Messier through 60mm refractor from last night. There were that many level of details as when I observed M76 through 110mm refractor (https://www.fzu.cz/~...ic/orig/m76.jpg), still I was surprised I was able to see easily two separate brightenings. The nebula indeed looked like a small Dumbbell nebula:

That night I was also sketching open cluster NGC663 (together with NGC659 and NGC654). This cluster was not on the list. I wanted to admire h and chi Persei and by chance I pointed the telescope right on NGC663. This was very lovely view. Beside few brighter members, there were more faint stars popping in and out with averted vision. All this on nebulous background. The cluster looked a little bit like a two separated clumps of stars. I noticed NGC654 in the same FOV - just a rounded faint glow around very faint star. I knew about the third one, but I had to look in the atlas to find exact location before I started seeing NGC659 at low magnification of 17x. I paid special interest in star colors. To my surprise, I guessed correctly some hues of 8-9 mag stars close to the cluster (4 brightest member of the cluster looked a little bit yellow to me as well). I was less successful in case of some brighter stars:

I see it continues. These are all very nice sketches of these deep sky targets.

Yes it does, Frank. Thanks.

 

Here are two more Messiers from last night. Not really through 60mm, this time with 82mm refractor.

 

m75_20180912.jpg

 

m30_20180912.jpg

 

By the way, I revisited some targets that I have been sketching through 60mm recently. It is quite a step from 60mm to 82mm!

And one more. With the Moon and all this haze I picked up small open cluster M103. In 60mm refractor, it looked the best at very high magnifications when about 10 faint stars started to show in addition to 4 bright members(?). There was a beautiful color contrast between one red star and remaining three bluish stars. This is a rough sketch directly made at the eyepiece with stars colorized later on in computer:

I revisited M103 with larger 82mm refractor. Transparency was still very good, yet the Moon was shining even more than last time. I was able to add just few stars.  Faintest recorded star in the cluster is of magnitude V=12.4. I know that on better nights without Moon, I could push myself with this refractor down to V~13.5. 

 

Red color of bright star in the middle was again quite obvious in particular thanks to the contrast with other 3 nearby bluish stars. Interestingly, O'Meara could not see this red color as I just read in his book The Messier Objects, although he was aware that many observers reported this red color. Visibility of colors greatly varies with the state of atmosphere, I guess he was probably observing M103 on such night.

 

OK, here is the sketch (these time redrawn completely on computer):
