Mallincam VRC 8" Ritchey-Chretien OTA Telescope - Carbon Fiber Tube
The Mallincam VRC 8" Ritchey-Chretien Optical Tube comes complete with a Electronics 4 pattern finder with variable intensitity control, Super Large 3" Linear Focuser with 2" and 1.25" adapter and 10:1 reduction speed focuser, lock screw, tension adjustment screws. There are three fans on the Mallincam Telescope to cool down the 99% reflective dielectric coated Quartz mirror including the battery pack with DC plug (batteries not included), 3 spacers to mate between the focuser and optical tube to achieve perfect focus with any CCD Camera. Combine with a telescope mount and pair with a your choice of Mallincam Cameras for excellence in both still and video astrophotography!
The Mallincam VRC 8" Ritchey-Chretien Optical Tube comes complete with collimation screws and lock down screws to align the Mallincam Telescope optics perfectly. A feat not found on optical tubes of the same type. You also get collimation screws to align the 99% reflective dielectric coated secondary Quartz mirror for perfect collimation. There is also two Losmandy D type Dove tail on top and bottom of the Mallincam Telescope optical tube for solid rigid mounting.
The Mallincam VRC 8" Ritchey-Chretien Optical Tube comes complete with Carbon Fiber tube for zero expansion of the optical tube. Coupled with both mirrors made of Quartz, the Mallincam Telescope VRC 8 provide a temperature stable optical system that will keep its collimation and focus all night long.
Don'''t forget... We carry many fine Mallincam Accessories, too!
