Hello all. I have a question regarding the structural strength of the Meade #932 45 deg erecting prism assembly. I searched so sorry if I missed a discussion on this.
I have a Meade ETX 90 on the way that I will set up for terrestrial spotting scope use with some of my existing eyepieces and what nots. I plan to use it with a 1.25" binoviewer and perhaps a DSLR. Though I know I can mount the DSLR directly without the prism, for various reasons I might want the correct orientation for the DSLR so it is possible I might use it with the diagonal.
I want to use a 45 deg prism, like the #932, since the angle will be nice for spotting scope use and I will get correct imaging (not inverted or mirrored). However I am not very certain about hanging my Canon 80D or binoviewer off of the end of something made from plastic. From what I understand the Meade #932 does not have an all-metal version, just versions with housings that are mostly or completely plastic.
I have two concerns here:
- Maintaining axial alignment for decent imaging (flex)
- Not worrying about the eyepiece breaking and dropping my binoviewer and eyepieces, or my camera, in the dirt.
So the question is, need I be concerned?
I know there are nicer, metal housing versions of 45 deg diagonals out there but I like the idea of the integrated telescope adapter with the Meade version, and the price of the Meade is lower though I know you get what you pay for in this hobby.
