M51 Whirlpool Galaxy

I found this tricky to process without getting too much noise in the background.

Scope: WO 81GTF; Camera Canon D & CLS Filter; Mount: iOptron iEQ45-Pro.

Exposure: 9 x 400s Lights, 4 x Darks & 10 x Bias calibration frames. No Flats though.

Processing: Stacked in DSS cropped and tweaked in PSE8 & PS. Guided using PHD2, sub arcsecond graph throughout. V. Pleased with the guiding.

Done
