Title: M106 in LRGB and HaLRGB, reprocessed
Description: I never was really happy with my M106, for whatever reasons had problems with artifacts in the stars (and made it worse in my previous version - I have to admit). Also Ha made the central regions of the galaxy to reddish. So I fully reprocessed. I find the result now more pleasing, in particular the Ha version (version D) with a much more subdued Ha.

Description: rather than somehow combining Ha and LRGB, I tried to more correctly only add the difference between Ha and the underlying continuum.

Title: reprocessed - without Ha (toogle Ha via mouseover)
Description:
completely reprocessed the data with a modified workflow (and a lighter hand on color saturation), in particular
1) added Ha data already in linear stage
2) new workflow including NoiseXterminator
3) stretching using the fabulous GHS script (thanks @Gunshy61 and @mike1485)
4) removing and re-adding stars with screen blend rather than simple addition (thanks Russell Croman)
5) have a reasonable workflow to correct chromatic error (in particular in blue) owing to Celestron's reducer
and many more little details/experiences

Title: M106 - next try
Description: M106 is a nice large and fairly bright galaxy to photograph, but somehow turned pout to be really hard to process. This holds in particular when Ha is added. So I did (another) full reprocess.

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. |
This image cannot be submitted for the IOTD/TP consideration.
