Pluto



 This was taken on 7.7.15 at 1:00am. from Austerfield. Pluto is marked and near the middle of the frame. It was done during a collimation session on the ODK12, just to finish off the evening. The camera used was a Canon DSLR 550D, set at ISO800 without filters, I should have added my usual IDAS filter but it wasn't needed for collimation and I didn't add it for this.
The 15 x 60sec frames were stacked by sigma-averaging in Astroart without calibration, then finally processed in Photoshop.
