This is obviously not a winner. It was taken in my driveway under bright street lights inside Orlando city limits. I used an Orion Starshoot Pro V2 Color camera mounted on a CGEM and using an AT72ED with ATFF. I autoguided with the Celestron NexGuide hooked up to a C5. There were 5 pictures each 5 minutes long and 3 darks. The image is cropped to 800x800 but not resized any. North is up.

Taken with the Full spectrum modified Pentax K10D camera.
Main scope: Stellarvue SV 4 with flattener and Baader Moon and Skyglow filter
Guided by SSAG on SV70ED with Maxim DL
Location: Montebello OSP, Los Trancos Woods, CA, USA
Lights taken on April 28, 2012

Stack of 13 lights: 10 minutes at 400 ISO
8 Matched Darks
Stacked with DSS 3.3.3 beta 45

Processed in PI with DBE, Masked stretch, Histograms, Curves. Exported to LR 3 for final touches before upload.

Difficult time removing amp noise at the edge of the frame. Tried using cold darks as Bias frames to help control the glow with marginal success.
