NGC7789 Caroline's Star Cluster - October 2021
Televue127is, ASI2600MC, A-P1100 AE Mount
IDAS LPS-2 Filter, Gain=0, B1x1
34*270s exposures - 2.55hrs
Pixinsight processed with Generalized Hyperbolic Stretching Script (part of testing parameter variation).
Stretching was done using a new Pixinsight script developed by Mike Cranfield employing my proposed generalized hyperbolic equations (still in development). Interesting trade offs between star halos, star size and star colour also star brightness vs background visibility - this was the result of trade-offs I made (ie. any poor choices were mine). Other than that, only background neutralization, noise reduction (MLT, ACDNR) and Photometric calibration performed.
Subject globular star cluster (yes, globular) was discovered by Caroline Herschel in 1783, who's husband also was an astronomer. Sometimes I see a rose, sometimes not - imagination and squinting helps.

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.
