Sh2-142 - NGC 7380 - The Wizard Nebula in SHO - Hubble Palette

The first time that I took a shot at the Wizard was as far as I can remember with difficulties due to setup, filter wheel, bad weather, etc, you all know what I am talking about 😊. Hence I had to come back to it since I believe that this is one of the most wonderful nebula in the sky, it has a special flair that I cannot describe (maybe the name Wizard plays a role here ... just kidding 😊). One thing I learned over the last year is that filter wheels seem to be great since you can automate all the sequences. But it also leads to 2 major flaws: 1. Since the filters are not par-focal (at least not mine!) every change of the filter needs refocusing, which I usually did not do since I leave the scope out in the yard overnight a lot of time to gain more integration time, and I did not want to get up at all those times (there is still work to do during the week). Especially my last trials lead to badly focused SII data, which I always regretted. 2. It leads you to not take enough integration time, each filter 2-3 hours should be enough, or? Well, it makes life much easier if you have more integration time. Hence I do not use any filter wheels anymore, rather the Baader UFC in this case or my Starizona filter slider (which is pretty good as well) and leave it in for the whole night. Next night is then the next filter. Processing was a tick more difficult than I thought it would be, but this is part of the journey of fun!

I still will add to this image RGB data with the Z61 and some extra wide field with the RASA in Hα and OIII, was waiting for the moon to go away and well ... yes ... for better weather, still in tropical storms times ...

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.
