The Dumbbell Nebula

Optics: CPC1100 at f6 on a Milburn Wedge
Camera: QHY8
Exposure: 41 x 5 minutes
Image scale at capture: 0.9 arcsecs/pixel
Guiding: PHD Guiding, using a Meade DSI Pro II on a Taurus Tracker III off axis guider
Date: July 5, 2010
Location: Vienna, Virginia, from my heavily light polluted backyard about ten miles outside Washington, DC
Processing: Stacked with Deep Sky Stacker, post-processed with Photoshop CS2 with maximum entropy deconvolution using a PS plugin from AstraImage
Image scale presented: 50% downsize

RA tracking was less than perfect this night, so I had to work on the star trailing with an offset filter in Photoshop. I also downsized the image.

other sizes: small medium large original auto
