24th Oct 2025 - Shipping to the USA resumed.

** NOTICE FOR CUSTOMERS IN THE USA **

* Please note figures below are illustrative and are affected by international exchange rates.

Royal Mail have now re-started service to the USA, however under new postal rules implemented by the current US administration, all orders, irrespective of value, will now incur a 10% customs duty, plus a fixed handling fee of $1. Royal Mails shipping charges to us automatically add this 10% charge and admin fee, however there is presently no other increase, so in most cases, where we were charging £11.70 for shipping (up to 250g) that will now look like the following:

Shipping method
Royal Mail International Tracked £11.70 (depending on location within US)

Customs and Duties charges
10% of order value ( e.g. order is £25.00) £2.50
Handling fee (irrespective of value of package) £0.50

Total postage costs (including customs and duties) - £14.70 ($19.59 at time of writing) (for this example)

Once again we would like to point out that these extra charges are being imposed by the current US administration and are beyond our control.

Seestar S50 OA-OAKv2

Seestar S50 accessories

I recently bought the Seestar S50 and as a seasoned astrophotographer wanted to use an EQ Wedge and dew filter. Online there were many suppliers of the latter but nearly all were asking 20-30€ postage, which I felt was too much. I stumbled across Oak Astro and was impressed by their continued development and fair prices. Also the equipment seemed very good quality. I had occasion on a number of times to communicate directly with Rob, who replied very quickly ( even on a Sunday ) ,and was very helpful. By pure bad luck, my order went missing and Rob tracked it down in less than an hour, the post office sent it to America instead of Austria. He immediately organised a replacement which arrived 3 days later. Despite Brexit problems, Rob has found a reliable way to send stuff to europe, it arrived at my door without me having to do anything other than pay the VAT due in Austria.
I was very happy with the quality, it was better than I had expected. I have tried most of the party out and they sork as expected. The only thing that could be better, would be if Oak Astro produced more similar products for astronomers and photographers, I would highly recommend them.

This is exactly what I expected and I am happy with it. Once the weather clears reliably I'll try it out - I'm mostly interested in the dew shield and filter holder.

A little pricey for what is 3D printed plastic bits…. But you’re paying for the R&D on a very niche product.

It does the job its designed to do excellently.

Just needs Dwarf 3 to add a setting that allows the user to tell it there is a dew shield on it, so it doesnt try to rotate the apertures towards the body of the D3 while there is attachments on.

Finally

Finally. A device that securely holds a filter and dew shield. The adapter for 1.25" filters is a very big bonus
