Testimonials

Real good folks who know and sell a thing or two about various scientific implements.

Jer Bear

Great company from the top down. Astrophotography is hard and they really helped me improve. Saving up for the 140mm refractor.

Ross Ferguson

Excellent source of astronomy equipment with knowledgeable folks working there. Highly recommended.
