Well made item. Perfect fit and saves damaging your equipment when attaching to your scope. As usual very helpful staff ( Martin ) when any queries or concerns when purchasing / aftersales of items. Fast responses and delivery.

FLO Compression-Ring adapter: excellent product

Excellent product, fit and finish, although a bit expensive. Take into account that it has a low profile and it will save some backfocus distance.

I had an expensive binoviewer almost drop off the back of my Orion 120ST because of the cheap and inadequate stock grub screws. This upgrade makes a world of difference and fits perfectly.

FLO Compression-Ring adapter for Skywatcher Refractors (M56 female thread) Asked FLO the question will this fit a Skywatcher Travel Star 102? FLO did not know well I took a chance and yes it screws on to the focuser drawtube. It hold the 2 star diagonal nice and firm much more secure than the standard two pinch screws and will not markup the nose piece. A touch expensive does the job well.

Great item

I really don't understand why Skywatcher don't provide these with their ED refractors as standard, as lets face it most people that buy the ED80, ED100 & ED120 generally image with them so to have your camera & reducer nice & secure is a must. I certainly feel a lot safer in the knowledge knowing my equipment is less likely to fall off. The same applies when using the scopes for observing as some eyepieces can be rather heavy too.
The item itself is well made & in my opinion a must have option to have as the 2 thumbscrews on the original just aren't up to the job.
I've brought one of these for the ED80 & ED100 I own & hopefully one day I'll get to own an ED120 & when I do I'll be doing the same thing.

Nice Item

Here we have a very nice and affordable low profile M56 to 2" holder. A good option to take advantage of the built in focuser.
