MARS DRAWING: J.D. Beish, Lake Placid, FL (27N21', 081W19')
16-in (41cm) f/6.9 Newtonian, Mag: 490x

Mars 10, 2010, 2320-2350 UT, CM 33.1 = 40.4, Ls = 62.4, De = 12.2
Seeing: 7-8. Trans: 6, Alt: 60 deg. OAT: 26.1 C

NOTES: BC = 0. Telescope performing great. Nothing unusual, Morning limb haze and clouds. NPR hazy with bright cloud at morning edge of cap. Evening clouds. Equatorial band cloud (EBC).

Wow, the astronomer's curse was lifted again!!! Scope maintenance done; new drive corrector working great, sky clear and steady. what more would an old guy want?

Guess it's too late to get started with my ToUcam on Mars. Jupiter will be next!

Jeff,

Love that drawing. What filter is best to detect the EBC? I've never had a chance to see it.

Thanks,

I think I used my artist stub or smudging thingy too hard so my drawing is a little weird. I use a W64 and switch off with a W47 for those cloud bands. A W47 is dense and I have to lower the mag done to 280 or so to use it, even with the 16", my eyes are not what they were. Can't remember if we call them Equatorial band cloud (EBC) or Equatorial cloud bands (ECB)

Wow, 16" shows you a lot! Very nice capture of the details, again.

The features are too large. Think a 2" globe outline is needed again since I tend to draw everything too large. Maybe then all my features will conform to my hand-eye-coordination, or rusty memory! That's what good seeing will do.

Thanks Sol. as I say, the old eye-hand-coordination is gone! Here is a redraw on a 2" circle, I will use this format now on, but I still can't get those details on paper like the old days. Oh well, getting older is painful.

Jeff,

Another excellent observation of Mars. You have recorded an impressive amount of detail over Mars using your outstanding 16" F/6.9 Newtonian. I also like the 2 inch drawing as it really brings out the detail better. You may have recorded Ierne (~133 degrees West) prior to separating from the North Polar Cap (NPC). I look forward to your future observations.

I took your excellent figure of the Martian North Polar Cap (NPC) from your observer's guide and added labels to the NPC remnants (Ierne, Lemuria, and Cecropia).

Carlos

Afraid my old artist skills are gone, Carlos. With so many eye problems, i.e. floaters, pucker, cataracts, etc., and my ability to draw has left the room. Maybe if I practice some more it will come back, but I haven't observed in a few years and standing on the ladder is difficult. Maybe soon I can sit on the platform and reach the eyepiece; that will help.

Jeff,

If your Mars observation above is a "bad drawing" I can only imagine a good one from you. I think it is excellent! Try to observe whenever your knees will allow you. The best of luck.

Carlos

Too windy to observe. Was all setup to but it would not be so great.

it's great to have some planetary veterans on the forum here Jeff, do you have a site where we can see your drawings?

Fantastic drawing.

I wish I was half as good.

I hope your health improves.

No. All my finished drawings are somewhere in the ALPO archives. I have thousands of Mars drawings on 5x7" cards. Too many!

Jeff,

Very nice detailed sketch. If you have any of your past sketches you should post some of them here.

Would but too many of them. Started drawing Mars in 1973 and did an average of 300 per apparition. Some are not so good
