Maarten Bloemen
Good product!

The guide scope was exactly as expected: good quality finish and worked right away. Shipping was fast. Still learning to work with the OAT, but the concept is awesome!

Makes Astrophotograhy better & easier

Got it up and running pretty quickly and it was definetly worth it! Via guiding Astrophotgraphy is now way more forgiving regarding manual polar alignment but also just better generally quality wise, allowing me to have longer exposure times.

Very well packaged and sent quickly

I only ordered the lens and it arrived in a reasonable amount of bubble wrap and protection. The Austrian Haribos were a welcomed surprise ;)

Everything fine

Parts were perfect.

Awesome and empowering tool. Took our astrophotography to a whole new level.

The OAT was easy to assemble, shows very good workmanship and design and is well documented and relatively easy to get up and running quickly.
With access to software features that every mount should have by default these days, and a demonstration of the awesome power of open source hardware, OAT has taken me and my partner's astrophotography exploration to a whole new level and brought us a great deal of good experiences in the short time we have been deploying it and using it.
Fabian and the whole community of OAT are very helpful and engaging and have provided clear instructions for assembly, setup and getting good results out of OAT as quickly as possible.

We love the project and are big time supporters of more to come.

Thanks OAT!
