I took this last night with the bright moon. FWHM 2.0.; 20 min exposures x 7

Astro-Physics 155 EDF f/7
STL-11000M
Ha 6nm 140min; bin 1x1

I'll have to wait for less of a moon to get the color data -- still a pretty interesting region in Ha.

I resized the image so it would fit the screen better.

Very smooth image Thomas. I've never seen all the nebulosity around the Triffid before. Excellent.

The Ha really brings out the detail.
