My previous guiding effort on M31 appeared good, so I tempted fate to move from 540mm up to 910mm for M33 and the Double Cluster. Using the Astrotech field flattener, which seems to do ok. Still struggling with color adjustments.

Title: M33 Revised

Description: This was my very second astro-image, and I really was new to the whole image editing game. The imaging run was late October 2021, five sessions ending on November 10th. At the time the first version was processed there was no way I was going to delete any of my hard-won subs!

Looking at it now, I see that much of the data was just not that good. What I ended up with was 5 hours 15 minutes in LHaRGB.

This image was also my test run for processing the Stars and the Target as separate layers. Using StarXterminator and NoiseXterminator as plugins necessitates converting to 16 bit. For this image, I just stayed in 16 bit the whole way. Also, I was able to try out some of James Ritson's revised Affinity Macros. This sparse data was probably not the best candidate, but they look promising.

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.
