M33 Triangulum Galaxy with a Dobson November 3.

Revision title: Color module and star mask

This is a live stack of 610 x 4 second subs (40 minutes) taken with a Dobson using a rotator and plenty of nudging to keep the image centered. The FITS file from the Live Stack was used to develop and process this image. With this longer integration I was able to use a softer Startools processing approach than the 10 minute capture from November 8. Mainly less photographic development, and less filter usage.

Final version tweeked further in Startools to bring out the core in more detail and distinct color, as well as accentuating HII and OIII colors.

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.
