Messier 5

Optics: CPC1100 (at f6.3, with a Celestron reducer/corrector) on a Milburn Wedge
Camera: QHY8
Image scale: 0.89 arcsecs/pixel, reduced to 33%
Exposure: 28 x 5 minutes
Guiding: PHD Guiding, using a Meade DSI Pro II on a Taurus Tracker III off axis guider. Dithering performed with Nebulosity 2.
Date: March 4, 2011
Processing: Stacked with Deep Sky Stacker, post-processed with Photoshop CS2. I downsized this to 33 percent because focus seems to have been a bit off. I began the series when the target was low in the east, and that may have made for an inaccurate focus as it rose higher in the sky.

other sizes: small medium large original auto
