NGC2403 LRGB full moon testing (John Favalessa)

NGC2403 LRGB full moon testing

My second attempt with my new ASI2600MM and LRGB filters. Data from my backyard bortle 6 with full moon. Prior attempts with LRGB in light polluted moonlit skies were failures. In this test I put my OSC Lpro filter on my flattener and then shot all LRGB mono filters. at least I'm able to process this data. couldn't get anywhere near correct color using Pixinsight's LRGB Combination, so I tried APP's Combine RGB tool. this gave me a usable file to process even though color is off a bit. With 2 filters at a time I probably need a lot more subs. The detail is good though, feel free to pixel peep. I keep non-cropped for wide field view/testing...lightness in bottom right quadrant is probably due to moonlit, I didn't want to push the dark point any further. Tonight I'll use my OSC camera with the Lpro for a comparison.

Description: a little decon to bring out detail in galaxy. don't think I can push it further. I'm fascinated by the number of distant galaxies that can be plate solved. This affirms that using a light pollution filter in front of LRGB filters in a full moon can produce a good image. With dual filters, I do need more RGB data to get proper color.

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.
