Mars collage from 4 sketchers on this forum
Posted 22 April 2014 - 02:31 AM
I noticed there have recently been posted - to my knowledge at least - 4 sketches of mars at roughly the same c.m. from people on this sketching forum. I thought it would be nice to put them together and took the liberty, if anyone objects I’ll remove it off course.
it consists of the following sketches:
David Gray 13 april 338°
Kris Smet 15 april 347°
Chris Nuttal 17 april 337°
Paul G Abel 18 april 320°
hope this doesn't offend anyone.

it seems there's a 'mini Mars frenzy' going on here with all the sketches being posted
I like this a lot. Here is a collage from 2010 that was posted here first and then on ASOD. Maybe we need to do another.
that's a good idea, we should start collecting sketches!

However in the this particular case it may be misleading without the context.
This was a particularly poor view (3” or 16.3”) with the seeing; and have had far finer views since (not that CM tho’!). In fact on the 19th Mars was so detailed in the 3” that my wife, even with her failing eyesight, could see a fair bit more than just the major features! It blew me away in the big D-K (and Saturn later!) and hope to post something of this and other recent fine views when I get the opportunity…… I might be retired but not enough hours in the day of late!
I have attached the original April 13 3” & 16.3” from my Mars 3 INCHER thread here with the contextual captioning – as reproduced here also.
“Seeing IV / III-IV
Here the drawing on the left
[3” OG] ‘doctored’ to simulate/approximate
the impression in the 16.3” D-K (x365 with
Binoviewer and Apodizer).
Blue tint in the limb mists/clouds very marked.
This representing the best moments in a
pretty poor view for this instrument."

RE the bluish haze, I have found this to be particularly noticeable on the fol. limb. Indeed in the observation here the haze seemed to be effecting the appearance of the Mare Acidalium. I wonder if the haze has been more prominent these last two apparitions. Attached are drawings I made two years ago near the time of opposition when a bluish haze was also quite prominent.

Our Internet is on but mostly off while BT sorts some line fault "By or before 30th April"..............!!
So not ignoring anyone!
My compliments, in the meantime, to you and all the fine contributors on here:

Even my 10 year old son loved it.

An impressive mosaic of Mars observations made by talented observers on this forum. It is interesting to compare the features detected by different experienced observers over the same face of Mars.
Davis- Impressive observations of Mars using your 3-inch (76 cm) refractor and 16.3" DK reflector. Thank you for sharing them with us all.
Paul- An impressive series of Mars observations over different longitudes. Thank you for sharing them with us all.

What if we agreed on a common CM in the future so that more observations like this assemblage could be had? It'd be different dates and times for everyone just like here but we could mark out calendars for the "common CM" view. Mars rotates so slowly in difference to us we could make use of an entire week for such a thing.
It wouldn't preclude our own efforts got personal reasons and choices but if we all kicked out a common CM view it'd be a fine thing in the future.
Just a thought.

Hopefully no-one will find that it gets in the way of their personal projects, as it is supplementary.
