Deimos with a Dobsonian and DLSR

[von Tom]

Imaging Mars this evening with pretty poor seeing in Brisbane I thought I'd give it a go to capture Phobos and/or Deimos. Shooting first and asking questions (of Stellarium) later I think I managed to get an image of Deimos. Phobos is too close to the planet's glare.

Canon EOS 600D in 10x movie crop mode, 6400ISO, 2000 or so frames each 1/30th sec at 30fps at prime focus of a 12" Sky-Watcher Goto Dobsonian. Stacked in Registax and various levels/gradient maps in Photoshop to bring out the moon. Stellarium image attached for reference.

Thanks for looking,

Tom

Here is a single frame from the video, and the stacked result prior to any other adjustments.

Thanks Derek and Luis. I've attached here a composite image of Mars and Deimos shot at different exposures.

I'm here to comment again.
It's not the first time I really admire one of your images Tom. They are different, fresh and interesting. Please keep up with such a great and creative work.

Hi Tom

That's an amazing capture, well done.

It's strange that it was only a few days ago I was thinking to myself if anyone has ever tried to capture the moons of Mars.

[von Tom]

Thanks for the kind comments guys. I have found that the faintest objects I can image with the 600D video (1/30th sec at 6400ISO) and the 12" Dobsonian is about the 14th magnitude.

Nice work Tom :)

Thanks Rob. Here is Mars about an hour later, seeing not very good.
