FORNAX MOUNTS AMBASSADORS
OUR BRAND PARTNERS:
Fornax has been developing and producing astronomical equipment for 20 years now. Our main focus is manufacturing astronomical mounts, but our range includes other astronomical auxiliary products. In addition to private projects we have been involved in such prestigious projects as the HAT (Hungarian Automated Telescope) project, one of the most successful projects in exo-planet exploration, or the BlackGem project. Our customers include Harvard and Princeton universities. Our mounts are used by many famous astrophotographers, and their award winning pictures taken with the help of our products stand as testament to the quality.
QHYCCD designs and manufactures world-leading astronomical cameras, ranging from entry-level to professional, CMOS and CCD, front-illuminated and back-illuminated, specially crafted for amateur and professional astronomers worldwide.
In a relatively short time, William Optics has established itself and its products as one of the world leaders in short-tube, highly-portable refractors, and has achieved quality recognition for many accessories such as the well celebrated WO Diagonals.
We plan to keep producing fine instruments both for the entry-level and the top-end segments. In the coming year, you will have many pleasant surprises: on top of a whole new range of larger Apochromatic telescopes, we will begin marketing new accessories and binoculars for all pockets.
Far from limiting ourselves to astronomy, in accordance to the founders’ passion for nature in all its aspects, we will increase our efforts to produce superior products for the bird-watching enthusiast and the casual observer alike.
