NGC 891

This edge-on spiral galaxy in Andromeda is also known as Caldwell 20, as well as The Outer Limits Galaxy and the Silver Sliver Galaxy (Wikipedia). The wide field image was simply amazing showing so many small galaxies, but I thought the cropped view really was the best representation. This was an unexpectedly fun target given the new tools of SPCC and BXT. Other than some (new) issues with overcorrecting flats, the rest of the data was clean and the drizzle integration looked better than the non-DI image. For the first time in a long time, I did not touch color balance after SPCC (or PCC). Did not apply any SCNR. In addition, I resisted the temptation to oversaturate the galaxy, and the end result, I think, is cleaner. Finally, this is probably the first image where I really didn't add any impactful additional editing in Photoshop; this was pretty much the appearance straight out of PI. To paraphrase Adam Block, it is a lot of fun to process (and reprocess) with these powerful new tools, and as a relative newbie to AP and PI, I can't wait to see what is next!

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.
