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 MallinCam VRC-8 optical tubes include a large deluxe 2" Crayford style focuser with 1.25" to 2" adapter included. This high precision dual speed focuser makes it easy to focus and lock the focuser in place. Variable friction adjustment and additional focuser spacer rings are included to allow you to reach focus with any CCD cameras or other optical accessories like diagonals, focal reducers, or Barlows.  The VRC-8 optical tube is fully light baffled, and has Quartz primary mirror and secondary mirrors.  Secondary and primary mirrors can both be collimated. Optics are Dielectric coated with 99% reflectivity! This scope comes complete with a bottom Losmandy mounting dovetail and Vixen style top dovetail for attaching to your mount.
