20210908 - NGC 7380 / Sh2-142 (CEP) - The Wizard Nebula - Second light with the TS140 and finally bringing some magic
What was the experienceThe first light is always a difficult one (getting to know the rig, correcting mistakes in the setup), and on top, I had chosen a rather faint DSO: M33 😜. But it has helped, and learning from all the trouble, my 2nd DSO with the new rig was a bit easier: NGC 7380.
The overlap of the OAG has been corrected, 2 nights of data, a couple of issues with the EAF failing, but still had enough data to process a new image, although still a bit short to be ‘perfect’ 😉, but didn’t want to wait for the magic anymore.
I only used RGB on this first processing, I still have a data-set of L and H that I will combine in a second pass. Colour of the DSO looks so much more natural compared to my previous images up until now with the OSC and L-Extreme.
The wizard has finally brought some magic magic 🪄 into my images.
Happy with the result 🤩
What’s in the picture(s)
NGC 7380 (CEP) - The Wizard Nebula -
https://en.wikipedia.org/wiki/NGC_7380Quote: “NGC 7380 is a young[4]
open cluster of stars in the northern
circumpolar constellation of
Cepheus, discovered by
Caroline Herschel in 1787. The surrounding emission nebulosity is known colloquially as the Wizard Nebula, which spans an angle of 25
′. German-born astronomer
William Herschel included his sister's discovery in his catalog, and labelled it H VIII.77. The nebula is known as S 142 in the 1959
Sharpless catalog(Sh2-142).[2] It is extremely difficult to observe visually, usually requiring very dark skies and an O-III filter.”

What have I learned from this
I’m gradually getting to grips with LRGB processing and getting all my data organised to have an easy workflow 😎
I still have the L and Ha data-set, which I will process in a 2nd pass, or wait for a more additional data (RGB-SHO) 😎
It’s a magical sight to see the RGB colours popping up on the Nebula 😍
I have become a sorcerer’s apprentice 😂
Clear Skies everybody! 🤩✨🔭
