I want to do Solor photography with my two systems, a Lunt LS60T Ha B1200, and a Celestron NS11 GPS, with Baader AstroSolar™ film Filter and a two inch Baader Solar Continuum Filter. Yesterday I set them both looking at the Sun, doing a comparison and I found something I did not expect. With the NS11 I needed a 56mm 2 inch eyepiece to optimize a whole view of the Sun. With the Lunt it was a 9mm 1.25 inch eyepiece. I just had not realized how different the focal lengths were. I thought I was done with 1.25 inch barrels, but the Lunt is expensive enough that I am not about to try to ask for more. These are just two very different optical systems.
How do I put a DSLR into the optical path to capture these views? One has a small lens, the other is very large. Yes, I can buy an Orion 5340 1.25 inch Universal Camera Adapter ($39.99), put in the Zhumell 9mm eyepiece and handle the Lunt, but what about the C-11? The Meade 4000 series 56mm eyepiece is just huge. I might buy ($119.00) a GSO 2" Camera Projection SuperView Photography Eyepiece - 42mm Superview, which allows the T threads to hide under the optical exit end.
Am I going in the right direction? Should I purchase these two items, or is there something better?
