Back Saver - Right Angle Viewfinder for Polarscope
I have lower back issues, and crawling down to align my star tracker through the built-in scope was a real challenge at times. The MSM right angle view finder let me polar align my tracker so much more easily -- me and my back are much happier! The finder is easy to use and the focus works smoothly.
Works well, reasonable price. And a must for a polar scope when you are north of latitude 60 degrees.
I have not had many opportunities to use it yet but it works as described once you get it positioned right. I’m using it on Skywatcher mounts with internal polariscopes. For my backyard setup I don’t really need it, it’s easier to just sit down below the mount than fiddle with getting the angle finder positioned right, maybe a parallax issue and I wear glasses - but the 2x magnifier is very useful for more critical polar circle alignment. Perhaps in different environments where getting down on the ground would be a problem then the right angle will be more useful to me.
The polar scope has taken the hard work out of polar alignment for me. It’s easy to use and saves me getting neck and back pain from squatting down and looking up in awkward positions. The luminous component to light up the reticle works well too. An added bonus is that you can use the right angled viewer on your camera eyepiece too using one of the supplied eyepiece adaptors.
This right angle viewer is easy to use and is a real lower back saver. I highly recommend it.
Saves awkward neck and back pains. Definately recommended. :)
I bought this item as an addition to the laser pointer I attach to the polar-alignment scope on my new Ioptron Sky Guider Pro.
I used the camera tracker to image Comet C/2022 E3 (ZTF) with an unmodded Canon 6D (full frame DSLR) with a Canon 70-200mm L-series zoom lens set at f/2.8, 200mm ISO 1600 (images submitted to Spaceweather.com’s Gallery pages).
The laser pointer and the right-angle viewfinder are great MSM products that saved me a lot of time and frustration. One of my pics even landed on the front page of our local newspaper!

This viewfinder easily attaches to the polar scope and allows you to take a regular posture and look downward into the scope rather than having to crouch uncomfortably low and look upward.
The right angle viewer and nylon connecter is a long overdue product with multiple advantages. First, it saves the user from having to stoop to look through the polarscope during celestial alighment. Second, the height of the tripod can be lowered since the user is now looking down into the polorscope. This helps to further stabilize the tripod against wind. The viewer is a nice addition to the MSM package.
