APO180FL Tube Rings

I was a little worried about the weight at first, but these rings are machined surprisingly smooth and the locking mechanism feels incredibly solid. They hold my OTA securely without any flex, which is exactly what I needed for astrophotography.

These rings fit my telescope perfectly, the knurled locking screws are easy to tighten by hand without tools. The inner padding feels secure enough for my heavy setup.

These rings mate perfectly with the scope's mounting plate, and the brass locking screws are a nice touch for preventing any slippage. Solidly built and exactly what I needed for a secure setup.
