below of planet Jupiter by YCAS member Mike Wenz on November 8,
2013 showing the Great Red Spot.

telescope. A DMK21af CCD camera was used with a Wratten #38A filter.

image above by YCAS member Butch Kimmel of Hanover, Pennsylvania
took this image with a new light pollution filter. It's a mosaic in four quadrants, 2 hours of light per quadrant.
Telescope was Meade 8-inch Schmidt-Newtonian, 812mm, f/4. 20 sub-frames per quadrant at six minutes exposure. Canon 600D (Astronomik full-spectrum modified by Gary Honis) with Astronomik CLS-CCD light pollution filter, ISO 3200. Dark and flat field frames applied. Pre-processed in Nebulosity and post-processed in Photoshop. Total project took six nights of shooting to complete.
Processed each quadrant individually before combining. It took three passes over all
the data to get it to this point. See larger photo here: M-31

observatory at John Rudy Park in York, PA using the York County's LX-200
telescope and his DMK21AF04 CCD camera. The images were stacked
using around 1000 exposures out of 1500 exposures and processed using
Registax. See: Lunar

and stared; the sky was lit,
The sky was stars all over it,
I stood, I knew not why,
Without a wish, without a will,
I stood upon that silent hill
And stared into the sky until
My eyes were blind with stars and still
I stared into the sky. --Ralph Hodgson (1913)
