WR 134 in H-mix(HO)-O withRGB stars

I was sitting a long time on this project, mainly working on the star integration. I might have overdone it a bit, but came up with a mechanism to reduce the star sizes to a (my) minimum. They seem a bit too sharp, but I did not want to start the process again (I guess if it rains more here then I will do that). My idea was to create masks on different levels of stretch, and eliminate this way all the bloated stars. At the end I added up all different masks to one and used it as color mask for the RGB stars with a highly stretched RGB image. I should have done the star mask generation a bit fuzzier, not sure if that would have been better, the future will tell. At least I have now an idea hoe to integrate the stars in a better way, if anybody else has a better one please let me know! I also obtained a set of Hß data to see if this would make a difference, and it did not, hence I will stay with the recommended list of targets for this filter from now on. I used it as Luminance at least.

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.
