IC983/IC982 AKA Arp117

Deepest image I have taken so far with my new ASI294MC Pro camera. IC 983 is the large SBbc barred spiral with the much smaller S0 elliptical IC982 at the end of one of IC 983's arms, reminiscent of M51. Lots nebulous blue knots can be seen in the bigger spiral along with the short bar. Hundreds of faint galaxies most fainter the 22nd magnitude can be seen scattered behind the galaxy. In fact, the majority of the fuzzy dots in the image are galaxies, not stars. The fan shaped diffraction spikes around the star adjacent to IC983 are caused by field rotation as my dob tracked the target during the nearly 36 minutes of total integration time used to acquire this image while I took a coffee break at the star party I was attending. The image is cropped to about half the dimensions of the original image to zero in on the target of interest.

Description: Reworked with Fitswork and more know-how on my part to get better contrast and color balance. Uncropped it to show multiple background galaxy clusters. Left a corner lost to image rotation.

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.
