Messier 33

The other night I managed to obtain the subs for this. The initial data for the red and green was tough going. The light pollution in the eastward direction was severe, and the stacks for red and green showed this clearly, with barely any real detail at all, and not much signal either. The blue stack was better. I managed 15 subs for red, green and blue each. I then took 132 subs in luminance, and every sub for LRGB was the same, at 3 minutes in length, which equates to an imaging time of 8 hours and 51 minutes. This is the best M33 I have taken and bearing in mind the conditions, I am pleased with the result. Have a good day everyone...

Description: I decided to present another version with a greater amount of LHE applied. I am never quite sure how much of this to use on this galaxy, because, for me, too much creates a sort of speckled appearance, which is not to my preference. Indeed, I would have added some Ha to it, as I would have done to my previous M31, but the nights do not permit, and I am always eager to move on. Hopefully this has created some more definition in the arms, without overdoing it. Thanks everyone...

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.
