M33 - Triangulum Galaxy - RGB enhanced with OIII and Ha

Revision title: More OIII added to blend

I revisited this classic target after 4 years with new gear, new knowledge, and new processing techniques. Still from the same backyard!

The revisions show different 'strengths' of the narrowband enhancements, while the original image shows the RGB data before any noise reduction. This was only processed with deconvolution, DBE, PCC Sd galaxy, HistogramTransformation just to give an idea about the data quality.

H-alpha data was shot in 2019 with my 80mm TS apo refractor.
Both narrowband channels were processed with the continuum subtraction method and blended with the linear RGB data.

I was really happy to see so many unexpected nebulae in OIII, including the recently discovered likely planetary nebula PN-G 133.7-31.4 (Maa 2).

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.
