M42 - SHO/HSO/RGB combo (Uwe Deutermann)

M42 - SHO/HSO/RGB combo

I never actually had time and weather to get M42 into my collection, and I also wanted to see what the RASA will do with it. Hence I decided to go out in the front of the house on the street (cul de sac, hence not that busy) since the backyard is blocked by freaking pine trees to the south. Had actually neighbors joining me for a little party with some beer while the scope was busy ;-), that was nice! Next step a good set of OIII and SII, maybe I have to wait for the next Winter for that.

Notable item: After several trials I have to admit that the Baader Hα 7nm filter is not the best for the RASA. Waiting for the Highspeed filters!!

Description: VERY weak OIII addition, just got 30 minutes of data. Created a H-HO-O version out of it. Hopefully I can get some more data tonight, clouds just moved in :-(.

Description: The "natural " look.
R= 45% Ha + 55% SII
G = 10% SII + 20% Ha + 70% OIII
B = 10% Ha + 90% OIII

Description: 2 nights ago was much better seeing, and I tried out the combo imaging. At the same time I got my additional OIII subframes I took RGGB images with my "old" 183C through the Williams refractor. The wonderful thing: almost same FOV. I cannot guide then though (might need to attach another scope .... maybe ;-)). Took 60 seconds for the OIII and 30 seconds for the RGGB. Combined all images together with the Hα and SII that I already had. I still have to tweak a bit more, but in general I say that this experiment was successful 😊.

Description: Tried out suggestion by John to sharpen image via HiPass filter in PS. Definitely working, although with these data (especially the SII data) not really improving.

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.
