Mars - 21st April 2010 new
      #3759414 - 04/21/10 05:21 PM Attachment (36 downloads)

A very strange night....

Started observing Mars in a bright sky at 19:30UT, very good seeing and very steady even at x300. Did the drawing over the next twenty minutes and very rapidly after that the seeing deteriorated to dreadful !!

Still managed to see the North polar cap which is very dull, Hellas above Syrtis Major was brighter than the NPC, as was Libya. Sinus Sibaeus was visible as a long dark elongation. No real detail at all just the major features. Mars is rotating to the quiet side now so I really do think that's it for Mars ........ maybe

The small image in the drawing is roughly the size Mars actually appeared.

8" F/6 Newtonian, x300
21st Apr 2010, 19:40UT
Seeing AII, deteriorating to AIII.
CM=309'

Dweller

Very nice sketchwork! Now you have me wishing that I hadn't given up on Mars yet! It is just at or past the meridian at sunset, so it's not over [yet.]

I especially like the way you represented Mars below in the actual size as observed. I did a similar sketch with actual inset size in November 2005 and explained that astronomers with trained eyes knowing what to look for will see much more than the casual observer and especially more so than those who do not sketch from their observations. *Perhaps I'll add that early one from 2005 to my gallery soon.

Maybe Bill P will assemble a later compilation of more Mars sketches as I think this one should be included somewhere.

Dweller,

An excellent observation of a shrinking red planet. You have made many excellent observations of Mars this apparition. Thank you for sharing them with us all.

I was looking at Mars last night with my ETX-125PE at a little over 150x. I was very supprised to still see detail very similar to your sketch. It was a very small disk but detail was plainly visible.
