My Best Saturn Yet! - this morn 19 Dec 05

Hi All, struggled out of bed at 3.30am to see Saturn washed out by the Gibbous moon - and almost went back to bed, but thought what the hell, I'm up now

Was very glad I didn't pack it in as it quickly became clear that the seeing was very good, in the region of 8-9 out of 10, there was naught cloud and it was dry (no dew), cold even (it was warmer in my A/C bedroom).

I had the Mewlon 180 setup under a tarp all night so it was well cooled and ready to go. Got maybe 5 decent 200 sec (2000 frame sequences) - the pics below from 900 frames out of the second one. Still haven't quite got the hang of saturn in terms of gain... seem to have run a lot more gain and drop the exposure to 1/10th sec (at 10fps) to get decent brightness. Seems very grainy in raw mode, but comes up alright in the wavelets.

Anyway, the one of the left is Astra Image LR deconvoluted and on the right, just an Unsharp Mask in Photopaint. Same 900 frames.

I'm very pleased, only wished I had the C9.25 setup as well as I would have loved it's extra light grasp and resolution with the excellent seeing.

Cheers
