Here is the same PN taken with NB filters through my scope (5 years ago) using a Starlightxpress H694 CCD with 4.54 micron pixels, providing an image scale of 0.83"/pix

NGC 5129

Hardly any exposure as it was only a very quick first light test image for the new camera and off axis guider setup. It will be up to you if you think the difference is there ...personally I don't think there is that much

Mike

Thanks for that Mike. Good comparison. I thought there would be more difference. Gives me something to think about.

I am amazed that you can do so well with a DSLR....!!

Here is my version with an astro CCD setup for your comparison too. I think you are very similar, but my scope is quite different with a much longer focal length.....

Thanks for the comparison Tim. The longer focal length shows.

Well that's helped, I think. I suspect this object is DSLR friendly though. And I know some are very very hard, like Abell 35.
