M106 (or NGC4258)

Is described here in Wikipedia.

M106 is a spiral galaxy in Canes Venatici, it is about 25 million light years distant. Another one that was really too big for the sensor on the camera and this was also a difficult one to process.

I imaged it with the 16" Meade and SBIG ST-2000XCM one shot colour CCD camera. 8 frames of 5 minutes exposure were captured using CCDOPS software. This was also used to calibrate the light frames and to stack them into a final image which I then further processed in Photoshop CS3.
