Excellent support rings
The 115mm PrimaLuceLab support rings are very well made made and designed. They work perfectly with my Takahashi FSQ-106N refractor. Provides for a very solid connection to my Eagle 3 unit.
Nice Rings, has thickness to add threaded holes if needed in future.
They worked great! They fit my TAKFSQ106 perfectly. They also worked well with the PrimaLuceLab dovetail plate
Very good product
