Title: Monkey Head Nebula during the Supermoon NGC2175
Post by: Carole on 15:00:52, 04 February, 2018
I have resisted imaging this target up until now as I thought it was rather boring, but faced with a clear night, on the night of a full Supermoon, I didn't have a lot of choice of targets.  Also since I live in SE London.
It was due to cloud up at around 11.30, so this was as much as I could get.

Very nice Carole. Is there some noise reduction used? it looks a little over smoothed if so. If not it would take a bit of unsharp mask or suchlike.

Thanks every-one.

Very little Chris, just a couple of iterations of despeckle in photoshop which does very little at all.  I am not a fan of doing lots of noise reduction. 

I will see what unsharp mark does to it.

Actually having thought about it, I did a high pass filter on the image, so I think that is probably the most sharpening it will take.

As suggested by Chris, duly sharpened.

I would try not using the de-speckle filter as I find it quite destructive to fine detail. Just my 2pth  ;)

I am surprised to hear that as I find it the least destructive of those available in PS.
