Artesky Doublet ED 90/500 mm f/5.5 Refractor OTA

Artesky apochromatic Refractor AP 90/500 ED OTA

The refractor is very compact with only 40 centimeters length and can be mounted on a medium-sized astronomical mount or a good photo tripod without any problems. A practical carrying handle makes the assembly easy.

The apochromatic duplet objective with air gap and the special ED glass FPL53 provides sharp and high-contrast images. Thanks to the multiple coating, the image is bright and rich in contrast. The fast focal ratio of f/5.5 also allows astrophotographic use with the appropriate corrector.

The twist-lock system of the ball-bearing 2" rack and pinion focuser enables perfect clamping on the axis. This is helpful for observation and essential for astrophotography. Correctors are precisely clamped, giving you a good star image across the entire field of view.
