Canon to Coronado PST

Hi:
I posted this in another forum also. I am having trouble connecting my Canon Rebel XT to a Coronado PST for solar pictures. I have used a t-ring and a 1.25 inch adapter for prime focusing. I have also tried a projection body adapter with a mead 15 mm eyepiece for eyepiece projection. I can't get it to focus. The focal point is to close to the scope. Has anyone done this and can provide me with how? Should I try a different eyepiece for the eyepiece projection? Thanks.

Jay,

You are either going to have to barlow your eyepiece (which inherently gives you magnification, perhaps unwanted) or obtain a new machined eyepiece holder which is shorter. There is a company around somewhere that was offering these. I will try to look them up. This is indeed a problem with the PST due to where the focal point sits. There may be others out there that have more solutions for you.

Hi Jay
I have a Lunt LS35 this has the same problem. I was able to achieve focus with a TV 2.5 Powermate and the powermate to t-ring adapter.
Hope this helps.
