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.
Pictured below is the VRC-12, a Video Ritchey-Chretien optical tube of 12" diameter, shown mounted on a Losmandy Titan equatorial mount (not included). The images were taken from the former MallinCam Observatory in downtown Ottawa, Canada. The VRC-12 has an aluminum tube, and includes: an electronic finder, super stable 3" linear 2-speed Crayford style focuser, three focuser spacer rings (50mm + 2 x 25mm) and two Losmandy D type dovetails for attaching to your mount.
