iOptron 300mm f/4 Imaging Newtonian Telescope Optical Tube Assembly

Ideal for deep-sky imaging with a DSLR or dedicated astronomy camera, the iOptron 300mm f/4 Imaging Newtonian Telescope Optical Tube Assembly features a fast focal ratio for photographing fascinating objects. The OTA's primary mirror is made of BK7 optical glass with a quartz protective layer. The tube has an 8x50mm finderscope and a 3.25' Crayford-style focuser with a 1.5" adapter, which is compatible with iOptron's Electronic Automatic Focuser. Mounting rings secure the tube to the 14" Losmandy-style dovetail plate for connecting the tube to a mount.
