Andromeda, I'm still very much in learning stage. But this attempt still made me happier then before. Tried with many 10s shots for R and G and 30s shots for Ha. 380*10s R, 260*10s G and 246*30s for Ha. All processed in PI and final touch in LR. Why no blue you might ask. Clouds fot that filter two nights in a row and the third night the automatic focuser failed to focus... Will be shooting B next opportunity. Also mixing with some longer exposures and masks in PI. Must learn more about masks and pixelmath.
Where is the sweet spot for exposure in Bortle 9. Core gets overexposed and background excessive at 120s even with the ASI294pro at -10 and 120 for gain. I'll continue to experiment with lots of short exposures. Maybe a mixture and pixel math will be my best way,
The short story is, how to best utilise the few hours of clear sky I have. How much difference will a bortle 2/3 in Hälsingland make. The plan is to go there in the early winter, hoping for clear skies....

Now doing the Adam Blocks fundamentals to get a grip on PI. Maybe that will squeeze some extra out of he data I allreahave.

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.
