Great kit

Great kit. Seems to be pretty good value, well made. I bought it mainly to try and help eliminating light from the side entering the lens. It seems to help without causing any vignetting which is what I hoped.

I am always leery of any online purchase but it went off without a hitch, UK to Canada. Shipment was tracked along the way.

Quick delivery and brilliantly manufactured and comes in a nice little bag

Quick delivery and brilliantly manufactured and comes in a nice little bag. Yet to use as clouds inevitably come with every new astro purchase. I love how they properly flocked the inside with quality flocking material. If you have a dwarf mini, just buy one, you'll not find better elsewhere.

Fits perfectly, raises the dwarf high enough to clear the clamp screw

You’ll be glad you got it with the filter holder.

I paired this with my OakAstro filter holder to raise the Seestar S50 above the SkyWatcher Star Adventurer Wedge so the S50 rotates freely and the filter holder does not foul the wedge. It’s a simple device but quite important to the overall performance.

A great business to deal with.

Searching for something for my SeeStar I came across Oak Astro. I received fast responses to my questions and a very prompt despatch (and delivery) of goods I ordered. Just the sort of business I like to deal with!

Simple and very effective.

It is hard to fault this device! I bought it because I wanted to add different filters to my SeeStar S50 and because I wanted to reduce extraneous light getting in. It works on both counts. I recommend users read the manual as the mounting flap could easily be damaged by not following the publiushed guidance.

S50 OA -OAKv2

All arrived in good condition, a nice update from the original set,just waiting for dark enough skies to put them to use

Game changer

Great bit of kit, dew shield and filter holder all in one. Its a clever design and a game changer. Make sure you read the accompanying instructions to make the installation and removal easier.

Superior Quality

All of the accessories are very well made and top quality. My favorite one is the dew shield. It has a little more length than other competitors and the internal flocking really make a difference.
