Ring Of Compression.
04 November 2022  | 

This is a great little upgrade for the 72ED Pro refractor. The original fitting is made of plastic with 2 bolts that are in an annoying position with my setup. However, this compression ring is all metal and fits perfectly. Bolts are slightly bigger and they are not in an awkward position. Highly recommended, as is the usual top class service from FLO. Just great all round!

Astro Essentials 2-inch Compression-Ring adapter for Sky-Watcher Newtonians and 72ED Refractor (M54)

I had been looking every where for this Sky-Watcher focuser 2 inch drawtube adapter. I couldn't find any in the USA. I did find a listing in Germany but they were waiting for a shipment to come in after the first of the year. FLO got me one here in Virginia in less than 4 days. This is a great upgade to the original adapter ring that comes with focuser. I was a liittle worried about the fit because of the odd ball measurements but this ring fits perfectly. I couldn't be happier with my purchase and with FLO for getting it here so quickly.

Pricey, fiddly yet better than the one it replaces.
18 October 2022  | 

It is annoyingly secure as even when loosened my eyepieces either won't come out or don't slide back in as the ring seem to interfere with the eyepiece / adaptor barrel. Maybe the ring has less tension it should have so it does not spring back properly or the way I swap eyepieces I tend to tilt them ever so slightly and then the undercut gets stuck on the ring. On the other hand it seems well machined and fits perfectly in the place of the part it replaces and doesn't mark my eyepieces even if I clamp down strong, its just the hassle when swapping. It is still better than the original one that comes with the skywatcher/orion single speed Crayford however I don't feel I am getting my money's worth in this instance.

Good quality item
24 March 2022  | 

Fits my skywatcher 150P just fine. It does seem to be a little bit higher than the stock one, about 1.4mm. Not a big deal but if your back focus is already a problem you need to take this into account. I only wish flo would have a shop on the mainland because with Brexit I now paid almost the same amount again for customs handling and import tax.

2" compression ring adapter
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.👍

12 March 2021  | 

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
02 March 2021  | 

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...
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.
