Subject: Re: Mars moons animation

Hi Tim:

Thanks very much for the compliment. Since it's an animation, and a single frame does not 

really look all that exciting (2 dots, big deal), I'm not sure if S&T would be the right 

medium - but I do this for fun, not fame anyway :)

Anyhow, do give it a try, it's less difficult than it looks. Capturing Deimos is relatively 

straightforward right now and probably for the next few weeks to come, I actually 

managed to see Deimos the other night in a 3.6mm eyepiece with the C9.25. Phobos is 

trickier, best chances are around one of its numerous greatest elongations. As a guideline, 

I would take rather short exposures (somewhere between 0.1 and 1 s) so that the 

overexposed scattered light around the planet stays within one Mars radius or so. Even if 

you don't see the moon on the screen while recording, it'll probably show after stacking. 

Have fun!

That is excellent work!  

Might I suggest you submit your results to Sky and Telescope?  It'd be cool to see it 

exposed to a larger audience.

...I've been thinking of trying to capture the moons myself, after seeing your results (I 

have 

a C-9.25 with a color Flea camera).   ...but I've got to wait until this rain clears out!  ;o)
