Medusa Nebula

This is a pretty faint nebula, an 8800 year-old planetary nebula, situated a little northeast of Procyon.

It’s surface brightness is very low. During the imaging session, the nebula was almost invisible on the monitor. I’m really surprised it came out so good. Obviously this is not a narrowband image, it’s created using a One Shot Color camera.

The Medusa Nebula in Gemini, NGC 2395 153x120seconds Gain 0, a bit more then 5 hours. The sky did not reach SQM 20 so it was not so good.

A little galaxy, far far away in a lonely universe

NGC2403 in Camelopardalis, image with SharpStar 76EDPH @ F4,4 Nikon D750 ISO 400 17×120″ SGP, PHD2, APP & PSCC (Click for a larger image) only 35 minutes. I imaged this galaxy to find out as a test how large it was (or how tiny!!)

The stars are a bit fuzzy as my automatic focusing did not work, I discovered in the morning why: it was jammed with the rotation know against the dovetail. Obviously, I tried everything apart from fysically checking, I re-installed about everything 😉 No Flats used so a dust bunny is visible here and there.
