NGC 7640 deepfield

Revision title: Rotated

In keeping with our theme of less popular objects in the vicinity of well known DSOs, we did an LRGB set on NGC 7640 in Andromeda. This galaxy was first catalogued by William Herschel himself in 1786 but he probably never saw it like this without the benefit of a 14 inch Corrected Dall-Kirkham telescope and a cooled CCD camera, and some very sophisticated deconvolution, stretching and sharpening techniques that I barely understand but can marginally use courtesy of the help from Linda Thomas-Fowler and Chris Kagy. There is a tiny edge on galaxy just to the left of the upper part of the main galaxy.

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.
