2" compression ring adapter
Monday, 28 June 2021  | 

I nice little upgrade to my 130pds, the 2" adapter which is supplied with the telescope doesn't really aid you confidence with 800 worth of imaging train hanging upside down and held on by just two screws, what the compression ring does is that it not only keeps things nice and secure by means of the increased contact surface area, but also does a better job of keeping your image train nice and square in the focuser. Nice little purchase was this.
Big thanks to FLO for the speedy delivery as always.👍

First up, excellent and very timely service, as always website very current on stock levels. Thank you.

Easy to fit onto Skywatcher 250P-DS
Much more secure and reassuringly solid feel when changing eyepieces/Barlows.

A must accessory

At last an M54 adapter that has a compression ring. Now I can enjoy precise centering of eyepieces, adapters & camera's, great for collimation & all without marking the outside of the barrel or without making that slight adjustment as with the previous screw type. Excellent product really happy with it!

Best product for Skywatcher telescopes...
Sunday, 20 September 2020  | 

I honestly don't understand why Skywatcher puts such an inferior visual back on their ED scopes. This product is a perfect fit and you can rest assured your eyepieces and adaptors will not get scuffed or beaten up. Great machining and paint finish. I ordered this from Florida and received the item within a week. Great service and products from our friends across the pond.

Well made

With a compression ring rather than just two screws this doesn't mark the body of any push-fit flattener or star diagonal. Some people have said it has problems with a tapered nose piece such as the OVL flattener has, but I have had no trouble with obtaining a secure and snug fit.

Big improvement

This is a big improvement over what is the standard fitting on the SkyWatcher focuser. My camera feels far more secure without damaging the barrel.

Huge improvement over standard SkyWatcher focuser connection
Monday, 4 March 2019  | 

I've a pair of Skywatcher newtonians - an 8" Quattro and a 500p. Neither came with compression 2" fittings, and given that both of these scopes are F/4 or lower, a Paracorr or similar is a really good idea for visual use. Unfortunately the standard SkyWatcher 2" eyepiece connection will not allow a Paracorr through to the focuser tube, meaning one cannot reach focus with the standard interfaces as supplied.
This compression-ring adapter replaces the SkyWatcher screw-in adapter that has two thumbscrews only, with a fitting that has the brass compression ring. This means that the Paracorr can fit all of the way through into the focuser and can be tightly held without any possibility of marring the tube of the eyepieces or the Paracorr itself.
This replacement fitting does exactly what it says on the tin, and then just gets right out of the way, exactly like the best designs do.
I cannot recommend this fitting highly enough. If you have a Skywatcher newtonian and either you want to use a Paracorr or you want to have non-marred eyepieces, then this is the fitting for you.
