You can always use a lot of artistic licence to deal with the issue.

Elephant Trunk close up from pier 1. Looks more like a pregnant eagle or penguin to me.

Alternatively, when available you can use the colour data from pier 14, in this instance the M16/17 job Florent submitted, with the luminance from the M17 image captured using pier 1.

Hi
Still in holidays with a very small laptop. I will try to correted the vignetting next week
But when I looked the fits keyword of flats , they have a strange 1700 focal length, different from light file.

Steve , the flats of pier1 are take with the same gain and offset of light ? Can you do flats dark of the same duration than flat ?
The overcoorect vignetting may be cause by different pedestral it seems

to the best of my Knowledge yes, however I will double check over the next few days

It may be down to the OAG light leek I mentioned ??

We are taking new darks this week just in case

flats we will re-do as soon as the small light leak is solved

Please ignore my dylexia wherever possible, just be thankful I can control my Tourettes ;)

Things to do, so little time!
