Whether you are new to astro-imaging, or a seasoned expert, we have you covered. We carry high-end Takahashi imaging scopes, computerized Celestrons, affordable, quality Orion astrographs, and everything in between. Astrographs are typically designed as refractors, however, they can also be Ritchey-Chrétiens or larger Newtonians. The type of telescope you use depends on skill level and desired celestial objects.

With the popularity of DSLR cameras, astro-imaging is easier than ever before. Take long exposures of the night sky or enjoy shots of swooping star trails. Watch as the serene surface features of the Moon or planets like Saturn or Mars come into view. Not sure where to start? Our experts are here to help! Take a look at our guide to Imaging the Planets.
