Hi Jim

Thanks for the kind words.

I also imaged M92 that night, but it won't be as sharp. After the first M92 luma frame was captured the turbulence went up to 6 arc seconds per pixel, which significantly blurs the stars. The difference between the first frame and the next 5 frames is pretty appalling, like you used a 15 pixel gaussian blur on the first frame.

The AT8RC scope has been really great to use, although I ams still looking for an affordable 0.75x reducer / flat field corrector for it. Most night the seeing isn't good enough to image at 1650 mm, and my old HEQ5 mount is showing it's limits as I'm on the ragged edge of weight limits too.

TTYL..

Hi Folks;

I had very good seeing on Thursday night and managed to image NGC 4565.

http://groups.yahoo.com/group/Astro_IIDC/files/DSO/NGC4565_20110429_MJA.jpg

Astro Tech 8" RC Scope, 1650 mm focal length (0.75 arc seconds per

pixel). Measured FWHM was 2.5 to 3.5 arc seconds, which is very good

for my area. !6 minutes Luma, 6 min Red, 4 minutes G and 2.5 minutes

blue.

TTYL..
