Hi to all
I've often played around with trying to produce starless images (nebulae with stars removed) but I've never been able to produce results that match the examples you occasionally see posted here. The current Astronomy Now magazine has information on a program called Straton that makes the process much easier. Anyway I had a go with one of my old Eta Carinae images and it looked quite encouraging. Not perfect as I had to manually clean up some stars that weren't removed properly but still a reasonable result. In any case the removal process would probably work better by tweaking the parameters - I just used the defaults for this image.
Anyway I thought this might be of interest
Cheers
Steve
