This data for M33 was taken by me about a decade ago. It features a relatively short RGB capture and a deep H-alpha exploration of the center of M33's disk. Included here is obviously the showpiece NGC 604 as well as many many others. I personally commissioned and optimized the telescope and instrumentation to try to acquire data like this and take advantage of the good seeing the mountaintop provides.

There is an older version of this astrophotograph I published in 2013 or so. This version is a significant improvement due to the fact it is a continuum subtracted version and the color mapping was controlled and blended in ways that were not available back then. Specifically the continuum subtraction and color mapping/blend were done using the new NB ColourMapper script.

I will be giving a presentation on 2023-11-19 at the 'Astro Imaging Channel' and demonstrate the script and techniques.
Of course, I demonstrate everything completely in my videos at my site at AdamBlockStudios.com .

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.
