Astro Essentials compression ring for Skywatcher Refractors M56
Tuesday, 20 April 2021  | 

This is a considerable upgrade to the 2” adapter supplied with my SW Startravel 120. Easy to fit and now anything connected to it is held securely. It is also worthy of note that this is slightly slimmer than that fitted as standard and therefore will not interfere with the amount of focus. (It actually gives a couple of mm extra in-focus.)
Before ordering the item I asked questions of FLO and their response was always prompt and informative.

Purchased for 100ED refractor. Excellent replacement for the supplied "excuse" of a 2" holder.
Holds accessories rock solid. Delivered super fast. Many thanks.

The past was as described. Quick response and delivery despite the Covid lockdown and delays in international shipping. The part was well wrapped and arrived in New Zealand in record time. Excellent service FLO.

Good tolerances. I use it on the ED80 and it fits well with good fitment of 2" pieces.

Purchased for my Sky-Watcher Evostar 100ED. Works great. Every Astro Essentials product I have purchased is top notch. No problem receiving stuff from FLO in the U.s. No import fees or delays. FLO has become my go to astronomy shop.

Little more to add to what has already been stated in the previous comments. Essential accessory. I don't understand how SkyWatcher continues to mount adapters without compression rings

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.

Very good much better and secure than the two grub screws to hold in the 2" barrel on the existing 2" mount
