StellaMira Reducer/Flattener for 90mm Triplet 15 June 2023 | Peter
Good service from FLO, despatched quickly but then delayed by Royal Mail for 48hrs.
The Reducer works well once the back focus is worked out, nice sharp stars right into the corners.
Perfect accessory for the 90ED Triplet 14 January 2022 | Nicholas
Solid, well-machined accessory. Used with my Canon 250D gave excellent round star results throughout the frame. Fits nice and securely by screwing into the telescope's focuser tube.

Got one attached to the Stellamira 90mm Triplet and a modded Canon 600D. It gives perfectly round stars in all corners right to the edges. What I like about it is there's no adjustment needed like the WO. You just screw it on and it works brilliantly.
FAQ

Q1. I can't find where to install a 2" filter on this flattener reducer?
The knurled rear adapter at the rear of the reducer unscrews revealing a M48 2" filter thread, I hope that helps.
