A Cepheus Jewel box: Cave Nebula

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.

Finally an acceptable M63

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.

M63 Canes Vanatici, Esprit120mm F7 & ASI ZWO 2600mc @ Gain 100, 6 hours and 55 minutes integration in 1 and 2-minute frames.
