Coronado PST solar telescope, Canon T-3 & BYE combo


Question

Dear Guylain, or anyone at all, has anyone in the Forum had any exposure to the Coronado 40mm PST double stacked 0.5 Ha telescope coupled with a T-3 (1100) or similar Canon camera? My real concern is the focus travel of the scope. Whether or not one can obtain adequate focus with this lash-up. I currently use the T-3 Rebel with a Tele-vue powermate 2.5X on my Celestron 11" fork mounted SCT and a white light filter for solar observation. Along with capture in BYE. This works very well for the most part, but I am trying to go to Hydrogen/alpha for more resolution and detail. I've read reviews of the scope itself, and most of them are very favorable, but none have shown the line-up of scope and camera combo. I would piggyback the PST on my 11" SCT for tracking the Sun and attach the camera to the receiver for the eyepiece using the proper adaptor and T-ring. This would work for mounting, but I worry about focus travel length? If anyone has used this or similar combinations, please let me know if it works or not, perhaps even post a photo or two? Thanks, clear skies, and regards, Dirty Harris Co.USA.

DH, Any Luck?  I was able to get my PST couple with my T3 using a basic 2xBarlow.  I think I had to direct screw it into the Canon t-adapter to shorten up the focal length but I did get some dece

There are numerous Images posted on AstroBin which list the Coronado PST as the Imaging Optics (just do a simple Search on the site). This would be a very good indicator of your ability to reach Focu

Thanks s3igell, I'll check out that web site and review some of their photos. And yes the Field of View will be quite different from what I've been using, but I believe I can get along with it  for now. My biggest concern was the back focus ability with my set-up, or being able to reach prime focus. The dog gone solar scopes are so expensive and understandably so, but a fella hates to put out that kind of $$ and then discover that it won't work on your equipment. Thanks again for the info, and if you know of anyone who has had some hands on exposure to the Coronado PST let me know. Clear skies your way, regards, Dirty Harris, Colo. USA.

One of the easiest ways to "touch and feel" a Solar Scope is to check in with your local Astronomy Club.  Any Club that does Public Outreach usually has 1-2 Solar Scopes for their Daytime Sidewalk Astronomy  setups.

That is some sound wisdom s3igell, I'll check into our local astronomy club and see what they have. I am trying to get my ducks in a row and be well ahead of the game before the Aug 2017 total eclipse. Thanks again to you and Guylain and all here in this Forum. Clear skies and regards, Dirty Harris.

Yes Aaron, we did get the lash-up to come together, and we got some pretty good solar flares/prominences and sun spots, similar to what you have shown. Also worked surprisingly well for the eclipse. We were fortune here in Grand Junction Co. with clear skies and 88% totality. The advantage of the Hydrogen/alpha filtering was evident. Thanks again to one and all for the info and guidance on this subject. D.H.

DH,

Glad to hear it.  I too was able to get some decent images from the eclipse although I didn't have nearly the weather you had.  The Ha filter does provide some amazing clarity.  I had done some solar viewing with an old glass filter many moons ago and that was alright.  I thought I had finally gone professional when I made a Baader astrosolar filter before the Venus Transit.  That gave amazing images and the detail was fantastic.  Never thought I would be able to see prominences with my setup.  Coronado hit it out of the park with the PST.  Brings a whole new aspect to the hobby.  Send us some images sometime.
