A surprisingly dynamic region in Cepheus, the Cave nebula and surroundings. This image was taken during 4 nights with the little 76mm refractor at F4,5, with the ASI2600MC camera and an IR/UV cutoff filter. Total imaging time almost 18 hours, in subs of two minutes.
Imaged with the Maksutov 180mm F/15, at full focal lenght of 2700mm !
Imaging over two nights in April, 314 frames were colelcted, 101 frames 120″ and 212 frames 60″ at Gain 100.
This gain value did not raise up to expectations, I could see more noise in the end result easily. Compared to what I’m used to at Gain 0 with this camera.
