Binoviewer for Celestron CR-150-HD6" Refractor ?
Posted 15 May 2013 - 12:45 PM
I had tried to use my Celestron bino viewer in the scope and found there was not enough in travel with any of my eyepiece pairs. Would this be a problem with any bino viewer?
I was very disappointed that I would not be able to view with both eyes as I have gotten used to it with my SCT's. I am hoping to find a solution to this predicament without having to spend a bundle on it? Any and all suggestions will be appreciated.
I had the bino viewer setup with the 2" diagonal in place with the 1 1/4" redusing bushing in. The skies are not going to be cooperative for the next 5 nights or so ,so I thought I would see what ya all have to say about the subject. I was just thinking about something. Would the bino viewer work if I used my 1 1/4" diagonal on the scope instead of the 2" diagonal? Not enough in travel is the problem as I stated. Please, Help.

A Prism diagonal will work really well. I have the Baader T2 Prism.

If you have a Barlow try putting the binoviewer into it and then into the diagonal. You will most likely have a magnification of 3X to 4X but it should focus. I think you will be able to find a 1.9X OCA for your BV for under $50. You might want to contact Harry at Siebert Optics, he has many different solutions for binoviewers and he stands behind his products. I'm not positive but I don't think a standard 1.25" diagonal will give you the in-focus that you need.

I should add that to use the scope in mono requires one extension tube!!!
