Works great, things just glow with wonder when used ! Like it a lot.
Orion H-beta Filter 2”
I am a pre-amateur semi-budding astronomer. I’m pleased with this filter performance. Gives detail as expected when examining dark nebulae, which was my intended use. My experience dealing with OPT has been exceptional. I’ve worked with other dealerships and I’ve found these bright people to be informative and expedient with product delivery. Reasonably priced too. I will be pruchasing product again from them in the near future. A happy consumer .
