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.

Excellent Accessory Set for Dwarflab Mini Smartscope

I recently ordered Oak Astro's dew hood,bahtinov focus mask and star diffraction set.
Firstly, I live in New Zealand, about as far away as one could possibly be from Oak Astro, I was highly impressed with the fast delivery time.
Upon inspection, the items delivered are robust, of very high quality and precision manufacture. The threaded components mate perfectly. The dew hood is internally flocked and has absolutely no internal reflections.
Owing to poor viewing conditions (overcast, cloudy nights) I have not yet had the opportunity to test the items on any astro objects, however I have no reason to doubt that they will perform as advertised.
The accessory carry bag is a nice bonus.
In conclusion, I highly recommend this product to other Dwarf Mini users.
