IC 342 (Hidden Galaxy in Camelopardalis)

The subs that go to make up this image are a right mixture of both different exposure times and also bin settings with the bulk being bin 2x2 and 4x4 so that I could get lots of data in a relative short period of time, if you count 31hrs as short!! A fairly quick image for me as this was only taken over 3 months Nov 2016 – Jan 2017.

A difficult galaxy to image and I have used two different NIR filters to capture most of the data. Ha was used to pick out the nebulosity in the arms.

The overall appearance of this galaxy is on the red side due to the dust in our galaxy preventing a lot of the blue light getting through.

This galaxy is the largest in the IC 342 / Maffei Group of galaxies, many of which are very faint and most hidden by dust. It’s my first in the group to complete, the rest, well, they will take a ‘little’ longer

There are ~ 24 galaxies in the group, but the list is not complete or set in stone as data from some is not good enough to be sure that they are in the group, again due to the intervening dust making the distances & size unclear.

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.
