IC 342, Spiral Galaxy in Camelopardalis

IC 342, also Caldwell 5, is a spiral galaxy in Camelopardalis. Only 7-10 million light years away, this should be a very bright galaxy in our night sky but it is difficult to observe due to the dust and stars in an intervening arm of our own galaxy. Thus is was given the nickname the "Hidden Galaxy".

I had not been very interested in pursuing this target due to the difficulty bringing out the galactic details without overwhelming the subject behind foreground stars. I finally felt up to the challenge so went digging in my library of unprocessed data. All I found was limited data from a system that is being infrequently operated lately. While there were 12 frames of 10 minutes each of luminance data, there were only 7, 3, & 4 frames of RGB respectively. So I had to alter several parts of my workflow to produce a satisfactory image. Most challenging was the imbalance in color noise due to the low number of green frames relative to the others. That required some off normal sequencing of noise removal in order to avoid color shifts at points where they weren't expected during processing.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
