I have what is probably an easy question for all you more experienced users about a dovetail bar.
I purchased this bar (see pic attached) second hand a few years ago and finally want to use it to mount a guide scope on my Celestron 8SE.
I've seen other similar bars say they come with radius blocks, but when I hold this bar against my OTA, it feels like it should mount snugly without them.
The problem is, the holes don't line up.
Im trying to identify the brand of this bar, and see if theres an accessory Im missing.
Any insight would be helpful. Thank you.
