Hi Folks;

After another 5 week imaging drought, I finally got a clear night where the wind wasn't blowing 70+ kmph or smokey.

Here is M14 taken with the AT8RC scope (0.84 arc seconds per pixel) at 1625 mm focal length. Luma binned 1x1 10 minutes, Red binned 2x2 3 minutes, Green binned 2x2 2.5 minutes and blue binned 2x2 2.5 minutes. Grashopper 1384x1036 16 bit camera cooled to +5°C.

Turbulence wasn't great and started off at around 7 arc seconds FWHM when I shot my color images - but dropped down to about 4 arc seconds FWHM for my Luma. I only get about 1.5 hour of real darkness a night now.

TTYL..
