Hi Folks;

After a week of rain, I had reasonably good skies last night and managed to image M92:

Measured FWHM was 3 to 4 arc seconds range (each pixel is 0.83 arc seconds). 10 minutes Luma, 3 minutes red, 2.5 minutes green and 2.5 minutes blue (RGB Binned 2x2) Hutech IDAS LPR. Sky background 8,000 ADU and there was light haze or possibly smoke in the air.

Compare the above M92 image to my previous attempt under poor conditions (4 to 7 arc seconds) here:
