The JMC-425TT MiniDob is a fully functional Dobsonian truss tube telescope kit that was designed around 4.25” f/5 optics. It will hold a primary mirror up to 5.4” in diameter with a focal length of 21” or less (vignette will occur on mirrors over 4.25” in diameter).

The MiniDob was modeled after the large aperture truss tube telescopes that are so popular today with amateur astronomers. The design criteria for the MiniDob was that it had to look good and work great. We went through dozens of prototypes in an attempt to balance appearance and function. Folks tell us we achieved our goal.

All of the MiniDob plywood components are cut from birch plywood using a CO2 laser in our own shop. The laser leaves a very clean, almost polished, edge with an attractive brown patina and the parts fit is excellent. If you enjoy kit building, you’ll find assembling the MiniDob a pleasure.

The MiniDob kit includes all the components required to take your optics and turn them into a fully functional Dobsonian truss tube telescope.* With the exception of the truss rods, all parts are precut with only minor fitting required. The kit can be assembled with gap filling cyanoacrylate (super glue), epoxy, or wood glue (aliphatic resin). The basic kit includes: Crayford style 1.25” focuser, spider, fully adjustable diagonal mirror holder, polypropylene baffle, Teflon and Ebony Star Formica bearing surfaces, adjustable primary mirror cell, mirror cover, all stainless steel hardware, and even a peep sight style finder. Not into kit building? Send us your optics and we’ll build a MiniDob for you.
