Well, it looks like this will be my best shot of Mars for at least the next two years. It's really small now, but I had pretty good conditions for imaging it.

Taken a few nights ago with a webcam, using an 8" Newtonian reflector at f/10 (2000mm focal length). At least it's recognizable.

Fantastic! I tried about a week ago when it cleared up after a big snowfall, and couldn't come close to what you have here. All my images had no detail...you have the polar cap and various shading of the ground in a webcam image. How many frames did you shoot that night?

Thanks, NovaTJ. The seeing was very good that night, one of the best nights for planetary imaging I've encountered when I was prepared for the task. I shot about 30,000 frames, and his image was created from a sequence of 1200 frames at 10 frames per second. I stacked about the best 150 frames from that sequence using Registax.

That's really nice! I like how you can see the polar cap on it.

That's very good. I've been able to view Mars with that sort of clarity, and at up to around 6000 or 7000mm I've seen it appear two or three times bigger than in your photo...but I've yet to get a decent image of it. My only attempt is far more blurred and soft than yours. Let's hope we get some more clear nights soon, with good seeing, so I can test out my new filters.

You did a great job ! I see both polar caps . I haven't even seen Mars yet this year in the scope . Guess i'm getting ready to maybe retire it .

Thanks, all!

The video that was used to create this image was acquired on a night with very favorable atmospheric conditions. Seeing was very good, I would call it 4 out of a maximum of 5, and I can't take credit for that. I can take credit for having spent many hours imaging the planets with my telescopes and webcam, so when these great atmospheric conditions presented, I was able to take advantage of them. I had long since worked out all the mechanical details - collimation, focus, acquistion parameters, etc., so setting up and getting started that night was a simple, predictable excercise. But as I acquired the first video I could tell it was not like other nights. As the video steamed in from the webcam I could easily make out the northern polar cap and varied surface brightness, which I had seen through the eyepiece but never before in my webcam videos of Mars.

I appreciate the kind comments and I am pleased with this image. I encourage everyone who has an interest in planetary imaging to get out and do it, so you will be ready when the time is right. Mars is receding now, but will be positioned favorably for a few more weeks, and Saturn is approaching its opposition on March 21. Though Saturn's ring tilt angle is low now and still decreasing, it is nevertheless a great subject with an unbeatable WOW factor!

Thanks,

Don
