Stuf1978 Posted October 26, 2020 Share Posted October 26, 2020 (edited) Taken over the last three nights while dodging cloud and sorting out dithering issues. Stars are a little funky as focus on the sigma lens is really difficult to nail down.

mackiedlm Posted October 27, 2020 Share Posted October 27, 2020 I think thats really good. I like the colours and the trunk and other features are showing well. For me though the stars feel just a little too sharp and particularly near the centre. But its a nice image with good atmosphere. 1 Link to comment Share on other sites More sharing options...

I think one of the issues is that this lens shows some slight coma even when stopped down so you really need to sharpen up the stars in post to clear it up a bit 😃 Link to comment Share on other sites More sharing options...

On my MacBook there is a distinct albeit mild green cast so I applied SCNR in PI - I think Hasta La Vista Green does the same thing in PS (Windows only). Hope you don't mind me sharing the result: Adrian 1 Link to comment Share on other sites More sharing options...

Hope you don't mind me sharing the result: Adrian Thanks for the compliment Adrian, appreciated Yes I can see the slight green cast now you have pointed it out. Thank you for having a little play with the image and removing the cast, there's a definite improvement I think it's always worthwhile sitting on an image for a little while once you think you are done with the processing as I find there are always slight improvements you can make. 1 Link to comment Share on other sites More sharing options...
