Frank Breslawski was so kind to let me use his Ha data for me to try out HaRGB / HaLRGB editing. Quite a task I have to say, to get the colors quite nice I had to a lot of fiddling with the channels. In the end I took 80% Lum of the Ha data, 20% of my own Lum data and the RGB. I had to significantly reduce the green channel to get the stars look more natural, still a lot to learn though

However the increase in details is awesome, even if it can't match the orginal image ;)

The FOV's were not all overlapping so I had to crop quite a bit. With the remaining resolution every bit of noise reduction killed a whole lot of details so I ended up to skip denoising, the data was great enough to get along without.

Thank's for this great opportunity to learn Frank

Description: Ok, gave it another go with a different approach. Just combined RGB saved as tiff. Saved the registered Ha and Lum as tiff as well. Used the HDR tool in Photoshop CS to merge the Ha and Luminance and used the result as Luminosity Layer for the RGB. Much more detail and less noise. A bit "dramatic" contrast here and there but overall a lot nicer looking

Description: Ok, ditched everything and started again. Just used the Ha data as Luminance and not my own L channel data. Way smoother now, I really need to get my Ha filter!

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.
