M 15 w/ Inset

An RGB image of M 15, w/ a detail inset, so we see the larger environs, as well as some detail in the globular itself.

Taken w/ a BabyQ and its 1.01x flattener, Optolong R,G,B 2" filters, and an ASI 6200 MM Pro cooled to 0C (it's warm here in Houston). Full field of view is about 4 x 3 degrees. This image was drizzled 2x, w/ a drop shrink of 0.9 and all processing was done in PixInsight w/ WBPP for preprocessing. First time I've used UnSharpMask w/ a stretched mask to highlight better detail.

There was some problem w/ weird colors in the larger stars, so I masked them and did a slight convolution. This makes them fuzzy, but did remove the unfortunate color craziness.

This was built from 30 x 60 sec subs for each of R, G, & B and appropriate flats.

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.
