NGC 7640 - Edge-on Galaxy in Andromeda.

This is a pretty faint edge-on galaxy in Andromeda, that you don't see many images of - you probably won't see it through the eyepiece unless you've got a big telescope, great optics and superb skies. Well, I certainly couldn't see it through my Orion Optics DX250. It has a magnitude of 10.8 and a surface brightness of 14.1 mag/square arcmin.

It actually looks like a disturbed galaxy to me, which is what attracted it to me, but on close examination I could find no evidence for the presence of an interacting companion. No quasars within a radius of 60 arcmin from ngc 7640.

It measures about 11' x 2.5', is classified SBc and lies at the relatively close distance of 19MLy.

My image comprised 50 x 2 minute exposures through my 10" f4.8 reflector. Camera was a SX H9C OSC ccd. Guided with my KWIQ guider using PHD software. Acquired and processed in AstroArt3 with some assistance from PixInsight and NEAT.

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.
