Hi Folks;

I finally got to use my scope last night after a month long "drought" where it wasn't worth taking off the cover.

I was hoping to capture Light curve data from CoRoT-2b first, but it was still in twilight when the exoplanet transit started, so I decided against it. That's the last time for imaging CoRoT-2b for this year as it's too far west and my next night time transit is in November.

So I imaged M27 and because the sky was still clear and fairly calm , I imaged M15 afterwards. Rain and or thunderstorms forecast for the rest of the week, so that will be it for a while.

I have only processed M27 (also helps generate more updated figures for the manual too) so far, but it looks pretty good:

C8 1125 mm focal length, Grasshopper cooled to 1°C, LPR filter, 10 minutes Luma binned 1x1, Red 4 min, Green 3 min and Blue 2 minutes binned 2x2. Captured, guided, stacked and image processing all done in Astro IIDC 4.06.00.

Thats 1.27 arc seconds per pixel and my measured FWHM is in the 4 to 5 arc second range, which is better than average.

TTYL..
