Unpectacular as the constellation of Camelopardalis (giraffe) appears to the unaided eye, so spectacular the surroundings of the galaxygroup around NGC 2634 look. It is full of swaths of IFN (Integrated Flux Nebula).
I am not sure wether the glow in the lower right corner is real signal or an artifact of unknown origin.
The image was created during the initial stages of the switch to the „dual rig“ and to N.I.N.A., with all experiments and findings coming along. And of course there was a lot to learn in the process of working with data of a colour astro-camera. The integration of the different data-sets of both cameras was comparatively staightforward due to some clever functions and scripts in Pixinsight.
In 2020 I imaged this group (then with the QSI) already:
