NGC 278 A beautiful small galaxy in Cassiopeia

NGC 278 is a small bright spiral galaxy in Cassiopeia.

The interesting thing about NGC 278 is that it has a high rate of star formation which occurs in an inner ring. Such rings are seen almost exclusively in barred galaxies, but NGC 278 is a unbarred galaxy. Dusty outer regions of the galaxy are relatively dark. It is thought that the unusual structure is caused by a merger with a smaller gas-rich galaxy.

Brightness is 10.8m. Distance is about 40 million light years. Apparent size is about 2 arcmin.

The image has been taken during 3 nights and consists of 316x1 minute unguided exposures.

The seeing conditions varied, so I was able to use only about 60% of captured frames.

The re-processed revisions C and D use 423 light frames. PixInsight WBPP script used the Cluster preset.

Description: Reprocessed the old stacked image using the latest variant of my PixInsight workflow. It turned out to be quite difficult, because the data was much worse than the recent images. Fortunately the galaxy is very bright, so it was possible to make the background darker in order to hide the color blobs and gradients.

Description: I was able to find darks and flats for the light frames. So they have been calibrated and integrated again in PixInsight. I think that the resulting image shows more details than the original revision. Comparing to the NGC278 Hubble image, most features of the galaxy can be recognized :)

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.
