IC 2574 LRGB

IC 2574 is a beautiful mess of a small and dim galaxy. It is 12.8 MLYs away. I see the formation of spiral arms taking shade in my image. When first discovered it was thought to be a nebula.

from Wikipedia - IC 2574, also known as Coddington's Nebula, is a dwarf spiral galaxy discovered by American astronomer Edwin Foster Coddington in 1898. Located in Ursa Major, a constellation in the northern sky, it is an outlying member of the M81 Group. It is believed that 90% of its mass is in the form of dark matter. IC 2574 does not show evidence of interaction with other galaxies. It is currently forming stars; a UV analysis showed clumps of star formation 85 to 500 light-years (26 to 150 pc) in size.

Lots of blue young stars/dust, not much other color. I think I'll try to grab some Ha and see what it gives. I had fun with the processing as the data was week, but with the tools I was able to bring it out fairly well. I'm really enjoying this image. I see lots of star forming regions. Due to windy nights, my guiding never got below 0.75 RMS probably averages 0.9+ I threw out 50% of my subs.

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.
