Saturday Mars

[Maurice]

Hi everyone

I've attached an image set of Mars taken in good seeing last saturday morning.

As usual C14, ASI120MM, 2x barlow, Astronomik & Custom Scientific filters + Autostakkert etc...

Approx best 1000 frames of 5000 per channel

best wishes
Maurice

Great images :thumbsup:

Is it better to take planetary images at a higher fcstop (f20) as you have? Sorry beginners question, but starting out on my quest for astroimaging.
Cheers, matt

Thanks for your comments Bob & Matt..

Matt, the f/ratio I use is matched to my camera pixel size to try and capture all that the scope can deliver when I get good seeing.

Have a look at http://www.telescope-optics.net/telescope_resolution.htm for a good discussion on telescope resolution, particularly about half way down the page where there is a discussion on the 'edge spread' function (more representative of planetary imaging) compared to the 'point spread' function.
