Congrats Bruce, were you guiding for your subs? The stars look good, maybe a little oversharpened inside the nebula in just a couple of areas but overall a nice image.

I was thinking the same in respect to the stars. If they were more like the ones around the outer parts of the nebula, I think you would hit perfection. Still though it's a great shot. I really hope I can find a position in my yard to image it this season.

In addition to the comments I made to Warren I'm wondering if these stars were a little overexposed to begin with??? Perhaps I need to try imaging this target as I would for M42 - take shorter exposures of the middle/brighter part and longer exposures for the rest of the image and combine them???? Just thinking out loud here... But thanks for your remarks Chris - I appreciate them.

Congrats on the nice M16 image and getting you obs running !! The way it looks I am curious about if the flats worked. The center seems a bit washed compared to outer area?

Yes, I was autoguiding and taking 200 sec subexposures. I believe the artifacts you mention may have resulted from my use of the minimum filter in photoshop. I tried to reduce the stars slighly so they weren't so overpowering. Perhaps I can come up with a different method to improve these stars a little.

Something you might try is once you have your image where you want it, and you feel the stars are just a little too much, do a Select/Color Range and Highlights. You'll have to deselect some parts of the nebula that this will pick up. When you see that only stars are selected, do a Select/Modify/Expand and try 3 pixels, then feather about 2 pixels, and then do a very mild (.5 - .7) gaussian blur on them. You might have to play with them a couple of times to see what looks best, but I have found that just blurring them a little bit brings the nebula out a bit more. I also use the Carboni Tool for reducing stars which I think works better than the minimum filter alone for reducing stars.

Hi Warren; I think that those suggestions are well worth trying on version 2. I have used these methods on other images but I did not use them on this one. Out of habit I scroll for the minimum filter - I need to use more of Carboni tools - obviously in conjuction with PS tools.

Thanks for the input.

Thanks

Always take some shorter exposures than 200 seconds -
say 30 s, & 60 s.
You can then put that frame as a hide all layer in Photoshop
& paint the inherent smaller stars - with their better colour
through using the paint brush tool.

This works great for the big bright stars.
