Good quality

Good quality,shipped fast. Unfortunately i forgot about the fact UK isn't EU anymore, so i had to pay importduty and tax. But the product is really good.

OA-D3OAK Dwarf 3 Optical Accessory Kit

Very useful kit esp. in areas with nearby light pollution, e.g. street lights.

It does exactly what it's supposed to do, and does it well.

excellent build quality and fit

excellent build quality and fit. Have used with my filter set and it performed flawlessly. It has become a valuable part of my outdoor arsenal of tools when heading out for an evening of night sky shooting.

Great accessory.

If you want to upgrade the Dwarf3, then this is a must to have.

Filter adapters are easy to use and fits perfectly. The dewshield is also a great upgrade for blocking light pollution and shielding the filter.

Can recommend this product.

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.
