H-alpha nirvana achieved Dennis! The resolution is great, so much to inspect in each image.
Thanks!

Thanks Oleg.
Yes, im testing the Baader 0.4x RG reducer. Need to optimize the spacing of the camera.
I guess i have to do mosaics anyways in the future with this setup.

These are remarkable images, Dennis, especially at this image scale. For me this kind of result is still only a dream. I think these images rank in the top few of images of this type that I've ever seen.

You mention you used 2 x LS40 etalons in a rear mounted double stack. Did you use housings from RAF camera for each of these etalons or do you have custom made adapters? I have a couple of LS40 etalons each with RAF housings and one housing will screw into the other with their male/female T threads for a compact double stack but I've never tried that at this image scale.

Wonderful images, Dennis. Seeing makes all the difference. It sounds like your seeing is excellent currently which shows in these images.

Thanks Lou, yes its with the raf housings, they are great.
Well for me it is a dream system, also considering that it didnt cost me an arm and a leg and its just doing what i wanted: high light throughput imaging in h-alpha ds.
