Ideal for lunar, planetary, and deep-sky viewing, the Advanced C6-R 150mm f/8 Refractor Optical Tube Assembly boasts a large aperture and long focal length that produce a high maximum useful magnification, so you can make detailed observations of your favorite extraterrestrial objects in the night sky. In addition to the optical tube, you get a dovetail mounting bar, a 60x eyepiece, and a star diagonal.
Optical Tube Assembly
- Refractor-style optical tube design is reliable, easy to clean, and requires none of the periodic collimation that reflectors do
- Large 150mm (6") aperture is ideal for lunar, planetary, and deep sky viewing
- f/8 focal ratio makes it a medium-fast optical tube that allows for reduced exposure times during astrophotography versus slower OTAs and provides a moderate field of view with eyepieces
- Long 1200mm focal length produces a high maximum magnification, allowing the use of shorter focal length eyepieces
- Anti-reflection fully multicoated optics maximize the light transmission through the system to ensure views are bright and crisp
- Resolutions of 0.93 arc seconds (Rayleigh) & 0.77 arc seconds (Dawes) will allow you to split close binary stars and see details of distant star clusters
- Rack-and-pinion focuser with a standard 1.25" holder
- Vixen-style CG-5 dovetail bar is compatible with many mount heads on the market
- Weight: 19 pounds
Included Accessories
Eyepiece:
- 1.25" diameter nosepiece
- 20mm focal length produces a relatively low 60x magnification
- 1.25" holder and nosepiece make it compatible with the most popular sizes of eyepieces and accessories
- 90° design places your head in a comfortable viewing position, especially when pointing the OTA high overhead
- Star configuration corrects the view horizontally, but not vertically
- Low 9x power produces a wide field of view to make alignment and star-hopping navigation fast and easy
- 50mm aperture ensures dimmer stars can be used for alignment procedures
- Includes mounting bracket
