NGC7000 again

[MarkS]

I did NGC7000 earlier this year but it had problems caused by the Sony bulb-mode star eater problem and artifacts caused by reflections on the inside surface of the adaptor:

So here's another attempt - another of my September images.  Almost 3 hours of data in 340 x 30second subs.  Modified Sony A7S on Tak Epsilon 180ED.

This is the first image I have completely calibrated and stacked in PixInsight.  I have applied no sharpening or noise reduction but the quality is much superior to the previous image.  Whether that is PixInsight or the 30 second subs without star eating, I don't yet know.  There are still artifacts from Deneb at the top right of the image but the bright crescent artifacts have gone.

Oooo that's lovely Mark.

That is amazingly good. Is there an artifact at bottom right just above the blue-white star? Looks like a reflection nebula. So much detail.

Gorgeous image Mark, it's like looking into a jewel box all those sparkling coloured stars.
