M101
Object: M101
(NGC5457, Arp 26)
The Pinwheel Galaxy - Spiral Galaxy
 Const.: Ursa Major
Camera: QSI532 Scope: Tele Vue NP127is Mount: Losmandy Titan
Filter(s): IR block Exposure: 12x8m Blank
Galaxy M101 in Ursa Major. A stack of 12 eight minute exposures using a QSI532 CCD camera on a Tele Vue NP127is 5" f/5.2 refractor. The image was calibrated, stacked, deconvolved and a Sigmoid Scaling was performed using AIP4WINV2. This image was used for the luminance channel of the color image shown below. This image has been resampled down from its original size of 2029x1337.
