M33 Triangulum "Pinwheel" Attempt 2 (learned more stuff)

This is another attempt after learning a lot of things since my last M33 pinwheel. This was taken on a full moon night with 10-15% cloud cover.

What I am doing now:

Guiding with PHD

Taking calibration frames (darks, flats)

Improving processing practice (deepskystacker, PIPP, photoshop, sharpcap)

Improved capture practice (not blowing out the gain, taking more subs)

This is 86 subs at 110sec each one-shot color. 15 dark frames, 15 flat frames. Captured in Sharpcap, debayered in PIPP and stacked in deepskystacker. Post-processing in photoshop (levels stretching and curves, cropping, gradient removal).

I have much more to learn but I am happy to see progress, hoping for dark clear skies soon. Although, this was a great opportunity to learn how to deal with sky/moon glow, heavy light pollution and cloud conditions.

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.
