NGC2903 with NGC2905

Revision title: Better Noise Control

Captured from my driveway. I had a little confusion about which designation was the right one for this object, 2903 or 2905, I guess the galaxy is listed as 2903 and a nebula associated with the galaxy has the designation 2905. Shot with my 82ED refractor with my 2x Barlow, yielding a focal length of 1098mm that was reported by my ASIAir. Still a very small object on my frame and the initial photo that I got after my stack was really unimpressive to say the least, and the Ha data was no where to be had. I didn't even know I had captured it. I used Siril for the initial photo, and even though I have had very good results from it in the past, it really let me down on this one. Anyway I decided I would rerun it through WBPP in PixInsight. Also I did do a drizzle of the data to see if that would make a difference, and man did it ever. It also yielded a 136megapixel 2.2gigabyte photo that my ancient computer really struggled with to process, but it did it, I use a full frame Nikon 810a which gives a 36megapixel image from the camera, drizzle it and that goes through the roof. I mean BlurXTerminator took over an hour to run, but as I've learned with this hobby, you need to have patience. I think the image could definitely profit from about 5hours more data, to really bring out the extended spiral arms. May have to look into that when the full moon isn't sitting 5 degrees away.

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.
