Hi Folks;

I've had two nights since September 27th when it wasn't cloudy, blowing 90+ kmph, snowing, raining or being blinded by dust storms.

On Nov 12 I managed to capture not bad Luma data for the Blue Snowball (NGC 7662) before it slid behind the roof here. Tonight I managed to capture the RGB data, right before it went cloudy again for who knows how long.

It doesn't look terribly blue to me, but neither do other images I've seen of it - more green blue than anything. I over estimated the brightness of it and the inner ring part has gone nearly white with 90 second exposures (need to re-shoot at 60 seconds). I had expected it to be closer to the ring nebula in brightness, but it's quite compact (about 40 arc seconds). Stacking it at 3x size brings out some of the small little nodes son the outer edge. I'd like to do it under better skies and st prime focus, assuming the skies ever settle down.

TTYL..
