Product Features
The Maksutov optical design is recognized for being a portable setup that is easy to use and has a variety of applications, making it an excellent choice for both terrestrial and astronomical usage. This C90 Mak has excellent optics with razor sharp images over a wide field. This spotting scope has a built in camera adaptor for SLR/DSLR cameras, requiring only a T-Ring (sold separately) to connect to the back of the C90 Mak. It has a waterproof body to protect it from getting caught in the rain or the spray from an ocean wave, but is not designed to be submersed in water. The C90 Mak allows you to swap out the eyepiece for any other 1.25″ barrel eyepiece. This spotting scope has a mounting shoe with two standard 1/4″-20 thread mounting holes so you can mount it on any appropriate heavy duty photo tripod. The front hole is for normal visual use, while the Therear hole on the mounting shoe better secures the spotting scope when a camera is attached.
The C90 is powerful enough to warrant an 8X21 Erect Image Finderscope that has a cross-hair view and is aligned with the spotting scope by with three collimating three screws. The eye relief for the finderscope is only 8mm, so users with eyeglasses will encounter vignetting of their view through the finderscope. The finderscope must be removed for storage in its case and has a quick release mechanism to ensure this can be done with ease.
