IC 10

Deep in the heart of Cassiopeia lies the nearest starbust galaxy to us. IC 10 is a member of the local group and is only 4.5 MLy away from us. Because it is a dwarf galaxy and because we have to peer through dust clouds in our own galaxy to see it, it is not well known or much observed by amateurs. Not surprisingly it has a large number of very luminous stars and starforming regions which can just be seen in my image.

Dont expect to see much, if anything through the eyepiece - this is a very faint galaxy, about magnitude 13.5. Even worse, it's surface brightness is incredibly low at around 17.3 magnitudes per square arcminute, making it the faintest object I have ever tried to image.

My image, which was acquired and processed entirely in AstroArt3 on September 25th from Weymouth between 10pm and midnight, shows little detail except a few HII regions and an area of dark dust cloud towards the bottom of the image. There appears to be no resolvable structure to the galaxy and in that respect it is a typical irregular dwarf galaxy.

This image consists of 75 x 60 second unguided exposures colour converted, summed and noise reduced in AstroArt. It represents the limits of my patience and imaging ability with my present setup!

Hope you find it of some interest.

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.
