I was going back and forth between my wide angle 80mm flak binoculars, my Meade 10"f4 SN and the star map, and shifting views between the correct view bino's and the inverted Newt started driving me crazy. Does anybody know how to get a correct view out of a Newt and still keep a wide field? I'm using a 27mm Panoptic, which is about perfect or this scope.

Something like this might work. But it's only 1.25". sad

Hi David,
Sorry to get off the subject here, but where did you get that mount? I really like it. Did ya build it? I have a really heavy refractor and I could use something like that.

Hi David
The only company that I'm aware of that makes a 2" erect image diagonal is Williams Optics, however it is a 45*. If you can so with 1.25" eyepieces or want to keep it straight thru than there are several to chose from and I would also suggest the TV Porro 1.25.
Hope this helps

I am afraid it will be more complicated than just adding a porro or 45 to your newt. Those would work on the direct image, but you have already added a mirror (the diagonal) into your light path. If you added a 90 degree diagonal, however, I think you could get an image that was right side up, but switched left-right. Try it and see if it works any better for you.

BTW, I am also curious about your alt bearing.
