Mars - 12 Feb

[brianb]

Another wonderfully transparent evening on Friday, with seeing which was above average by local standards. I tried imaging Mars at f/20 and at f/40, after careful processing the f/20 images are superior - the seeing just wasn't good enough to allow f/40 to work properly.

Anyhow, here's the result:

2010 Feb 12, 2246 UT. CM 258 deg, diam 13.5 arc sec.

Celestron CPC1100, 2x Powermate, Astronomik type 2c colour seperation & Planet Pro 742 filters, Imaging Source DMK21 camera.

Transparency excellent, seeing moderate with constant boiling amplitude 2 to 3 arc sec. Wind calm, temp -1C.

Wonderful result Brian. The RRGB image is especially well detailed, although the IRGB is a little sharper.

Nice work.
