Here is image that I took while experimenting with SNR calculations and viability of using planetary camera for deep sky photography (sensor is sensor thus was concluded :D )

Equipment:

Newton 200/1200 on HEQ5, unguided but PEC applied, QHY5IILc as imaging camera, GSO x0.5 focal reducer (effective reduction ~x0.65)

Data: ~ 520 x 10s light frames (540 taken, about 520 stacked), 64 dark frames, total integration time: ~ 1h 27min, FL 770, F/3.85, resolution ~1"/pixel
