Helix Galaxy/NGC-2685

The data for these images was taken at SRO back in 2021-2022. The mirror was likely not in the best state of cleanliness at the time. The data was culled for best frames and processed in Pix Insight as are almost all are. Some slight enhancements were made using Photoshop CS5.

This galaxy lies in the constellation Ursa Major. It is also know as the Helix, Pancake, and Spindle galaxy.

This and the next images uploaded were all taken remotely from SRO. I lesson learned too late is to be sure frequent flats are taken and saved for later processing. The data from this scope ranges from 2016 to 2023 with this 12.5" RC. Over the years the flats have varied.

With the new 24" ASA600 all calibration frames will be acquired on each run. The download times of the new camera, AC4040BSI has a download rate of about .5 seconds per frame making sky flats much eassier and faster.

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.
