Mars Observed Feb 6 2010- Pastel Impression new
      #3608694 - 02/06/10 02:21 PM



I observed Mars from 7 UT ~ 8 UT Feb 6. *On the evening of Feb 5 11PM ~ 12AM Pacific Time. Opting for the Nexstar 5i with 6mm Orthoscopic and 5mm Super Plossl eyepieces to produce 200 X ~ 255 X magnification. Although seeing was medium to good at brief moments, varying winds distorted the view for the majority of the observing time. I referenced The NASA JPL Simulator and an amazing photo taken at the Pic du Midi as posted by J Luc in the Solar System Imaging Forums. It shows a dust storm over the North polar cap on Feb 2 so I rendered that in the lower artists conception landscape. I rendered what I could see in slightly blurred albedo, two large features, I'll allow others to identify. Yet the north polar cap stood out well and at times blue limb hazes were quite visible on the planets eastern limb and especially at the south polar region although no defined south polar cap was visible. Use of an older Orion Sky Glow Filter with a subtle band pass, renders the albedo features as slightly turquoise ~ grey-green.

The pastel sketch is on 22" X 30" Stonehenge 100% black cotton fiber pastel paper with use of various pastel chalks. The sketch was photographed under a north window with a Sony Cybershot 5.1 mgpxl digital camera.

I like the rendition of the dust storm. Another work of art.

S1mas, Frank, Mr.Wang, Dweller, Jef and Rerun

Thanks for the kind words. I should reiterate that the reason I called it an impression is that I borrowed from many sources to render this. I actually spent a few hours researching the web and the most up to date photo images aside from observing Mars for about an hour through the telescope, frustrated that I could not see the finer details. If one steps back from the screen say at least 25 feet, allowing the fine lines in the sketch to coalesce, the image will appear similar to what was seen in the eyepiece. With only a Nexstar 5i or my 10.1 f.4.5 Dobsonian, I am quite limited to seeing only the major features on Mars so those are what I kept to intend to render here. I did not really complete it the way I had intended as the overall color of Mars should have shown a slight pink~flesh color as seen through my Orion Sky Glow Filter or as it appears in Hubble photos.

Perhaps I’ll add the pink color later without changing the lines or general albedo features. Subltle sketch changes will also add to a possible stereo 3D image for online as I study this more to actually produce two large mated hand sketches for original 3D display soon.

Mark,

When I first opened up your post and saw your rendering/observation I thought I had traversed time and was viewing a Bonestell painting. Your observation is phenomenal and the addition of the Martian landscape below is outstanding. The rendering of the Martian surface gives one the impression one standing upon Mars during a dust storm. Thank you for sharing it with us all.

I have labeled the major albedo features in your outstanding observation of Mars. I hope that you like it.

Carlos

Thank you; I'm glad that you both liked it.

Also much thanks again to Carlos for the fine labeling of the surface features.

Thanks for your compliments. I suppose I have created more sensational images aside from a few accurate sketches from direct observation lately. So here is yet another. I have been researching the 3D or stereo effected images lately.

The original is on the left and the right is a reworked newer version. If one employs the ‘relaxed-crossed-eyed’ method of viewing you should see a three dimensional effect, especially in the foreground rocks.

Mark,

The new version does appear more three-dimensional. The planet and foreground rocks do appear to jump out at you. Thank you for sharing it with us all.

Mark,

Agreed, I can see this more 3-D with the relax approach. Nicely done.
