. It seems that there are few right-angle finders on the market. Why?
I think it is a cost issue, they will sell more if they can keep the cost down. It is easy to make it right angle by buying a star diagonal. Quality varies on these, I prefer to make my own choices on what quality to buy. On the Grim making the finders right-angle would render them useless, IE it all depends on your optical system. I have always found a device like a telrad reduces neck craning a great deal and you don't need to be old for this to be a problem. Greetings and Happy Saturday...
At age 62, my neck no longer supports standing on my head nor does it allow for greater than ninety degree rotations either direction of straight ahead. For that reason, I am looking to implement a right-angle finder scope for a Dobsonian that I have.
I am aware of two commercial products. These are: 1. Orion 9x50 Illuminated Right-Angle CI Finder Scope ($129 at Amazon) 2. Orion 9x50 Right-Angle Correct-Image Finder ($89.99 at Amazon)
There may be others.
My questions are:
1. It seems that there are few right-angle finders on the market. Why? 2. Could one use a "standard" finder scope and mount it at right anges with the use of a mirror? In other words, mount a mirror on the scope to direct the sky image away from the scope at a ninety degree angle and use a finder scope to look into that mirror. Could this not be a $10 solution to a $90 problem?
This is my first post here so, if there is a FAQ somewhere on this topic, please let me know.
