NGC 925 | The Seldom Seen Galaxy

While this is not as rare as some of the objects Gary Imm is imaging, I count only 25 NGC 925 images ever uploaded to Astrobin. At 10 arc-minutes in size it's small but not truly tiny - about half the size of M110. The galaxy covers about 450x700 of my pixels at .73" image scale.

I found a consistent gradient just below the galaxy which colored red initially. Since the gradient was consistent across nights and filters, I suspect/suspected that it could be an Ha emission field. But I could find no evidence of that in the few wider-field images I could find, so I removed it as a gradient.

Calibration, registration and rejection in CCDStack. HaRGB combine, color calibration, and ABE in Pixinsight. Ha added to Luminance in Photoshop via a masked screen layer. Sharpening via HighPass and Unsharp mask. Noise reduction in Topaz de-noise 5.1.

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.
