Have given me thsnks My preferred method is by partially stretching in Histogram Transformation, then removing the stars in Starnet. Complete the stretch in Histogram Transformation. After this extract a lum mask from the image, apply it, and with the use of curves, you will be able to bring out more detail, if it is there. You can introduce the stars back into the image later. 1 Quote Link to comment Share on other sites More sharing options...

MarkAR Posted November 12, 2021 Share Posted November 12, 2021 A good effort on Orion, getting more data will be a real bonus. Orion is a very tricky target by all accounts and really benefits from taking different length exposures (and more of them). You can try some 10 second, and 60 second sessions and combine using HDR Combination, some really good YouTube videos on the subject. Also you might be able to reveal a little more faint nebulosity by not making the background quite so dark. 1 Quote Link to comment Share on other sites More sharing options...

Depending what mount you have, I wouldn't go beyond 30s. Maybe even lower if your stars are egg shaped.

The stars on your 30s images look to be OK, so maybe you could try 45s exposures. 1 Quote Link to comment Share on other sites More sharing options...

TerryMcK Posted November 13, 2021 Share Posted November 13, 2021 When I use my modded DSLR I always have it set no higher than 800 ISO as that is good enough. In fact from memory I think 800 is the one I always use. Any higher and it introduces much more noise. 1 Quote Link to comment Share on other sites More sharing options...
