This deep sky object is so small, its only 3 x 3 arc min. However, its about 2000 ly from us. The image shows also, the spiral galaxy IC 1296 at top left. This distant galaxy is 200 million light years from us. Gear setup: Celestron 127 Mak @f/ 7.5, Meade 6.3 F/F, ZWO mini guide 30, ZWO ASI 120mm-s, ZWO 294MC pro cooled @ 0, Baader UHC-S, iOptron GEM45. Acquired by APT, PHD2, 38 x 5 min subs dithered, 20 Flats, 20Darks, 20 Bias. Total integration is 3 hrs & 10min. Stacked by DSS and processed by PS 2020 CC. Imaged from sky Bortle 4 and cropped.

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.
