A moonlit veil - reprocess if you like

[pete_l]

Here is an hour of the Veil nebula from last night. 60 x 1 min @ ISO3200, due to the nearly full Moon
This is through my ED80 + FR + modded Canon 1100d
The sample image here is cropped, has had flats applied, stacked and some basic levels and contrast enhancement.

If you'd like to have a bash at doing some work on the unexpurgated version (after flats and stacking, no more) it's on my Google drive and you can download a copy from here

Be aware it's a 10MPix compressed TIF that weighs in at 118MB.
I'd appreciate any results that people are willing to share.

Thanks for the data to play with!

This is my first attempt, but nothing very special in processing.

Was there something particular you were after?

Not really. I put it up to see what people could make of it.

Where the trade-offs between noise and colour/contrast were. What "undiscovered" stuff can be dragged out. If it's possible or desirable to make the stars smaller?
it's just for a bit of fun, really.

I seem to have ended up with slightly reduced stars, obviously different colour balance, and some smoothing of the nebula itself, but I don't think I uncovered anything you didn't.  Let's see if anyone else does something different.

Gave it a quick try. Ended up with some huge stars compared to you though...

A quick go at your image:

mainly star reduction on medium and small stars

increase contrast & colour boost

How do you reduce star size?  Everything looks a bit more in focus in the last two pics.

How much night do you get where you are?  Here in sunny West Sussex there are no full nights at all now, you can just see Jupiter for a little while, and the Moon, with a little more, briefly, if you can stay up until 1am.

So I'm taking an enforced two month sabbatical from the night sky!  Time to do some fixing up, new home-made Bahtinov (second try), converted tool-shed into Obsy (tools now in garage), complete Arduino automation etc etc etc.

Dunno in PS, but in PixInsight, you create a star mask which selects "donuts" round each star. Then you erode the image in these areas. This shrinks the stars, and fades small stars.

Here in deepest, darkest, Andalucia we get about 5 hours of astronomical darkness at this time of year. It's one of the advantages of being closer to the equator. The down side is that winter nights are shorter.

The other down side is the mosquitos.
