 M101 Supernova
 
This is 25 min. shot of M101 Supernova.  It was an interesting effort because I had clouds at the East, South and West, but just the little patch of M101 was clear for 25 min.  Obviously, there was a big tonight and give the amount of light left before sunset at 8:45pm, I decided that autoguiding was going to be futile, so I track the object on sidereal+PEC and I did 30 seconds shots before the clouds totally rolled in and took away this beautiful DSO.
 
Camera: QHY9M
Filter: Luminance
Focal Lenght = 380mm
Telescope = William Optics Lomo Super APO 480mm + TV0.85 reducer
Autoguiding = No
Sequence  50 x 30 seconds
Processing: Darks, Bias, Flats.  GradientXterminator and Photoshop CS4 for levels.
 
 
Enjoy it!
