Are short imaging scopes better for binoviewing?Posted By nick munkenbeck |
Hello all,
I am told that some people shorten their refractor OTAs to achieve focus...
Would a short imaging APO OTA like the Televue 102iis or the Takahashi FSQ85 be a good choice for binoviewing with a 45 degree erecting prism?
I believe both are designed to bring the focuser closer to the objective than in the standard models for use with long imaging "trains" and come w/ extensions for visual observing.
It would be great to be able to binoview w/ a 45 degree erecting prism w/o having to use a 2x barlow for a wider FOV.
Thanks & clear skies,
_Nick
