MALLINCAM VRC-10T Truss Tube

What is the difference between our optical tubes and all others from various vendors? Each and every MallinCam VRC line optical tubes are shipped via Air Freight to our warehouse from the manufacturer to avoid sea salt contamination that can shorten the life of your optical tube reflective coatings. Other vendors  use sea  containers to ship their optical tubes from the manufacturer which exposure optical elements to sea salt for months of traveling by boat.  We also check collimation on every optical tube prior to ship them to clients ensuring top quality. That's the MallinCam difference.



The fit and finishes are simply unsurpassed by any companies
offering similar Ritchey-Chretien Truss tube optical system.
We test and inspect every optical tubes before we ship them.
If you are looking for high quality affordable large-aperture, large format
DSLR and CCD and Video CCD camera imaging for the dedicated
astrophotographer and educational institution, look no further.
The VRC-10T is the professional choice at an affordable price class.

Central collimating circle is included with every MALLINCAM Ritchey-Chretien.
Exclusive to MallinCam VRC line of Ritchey-Chretien optical tubes,  the super large size focuser
is well suited to support full size ccd cameras. Easy smooth dual speed focuser allow precision focusing and a lock screw hold the focuser in place night after night of imaging.


Every VRC RC models include  the MALLINCAM brand laser etched  proof of these instruments are truly custom made to our specifications of the highest quality. A standard Losmandy type 2" Dove tail is included on the bottom and top portion of the VRC-10T Front secondary collimation is possible through three holes mounted at the front of the central secondary mirror.
