AstroSystems Primary Mirror Cell

---

AstroSystems computer designed Primary Mirror Cells are made from a frame of 1.4" thick, 26 layer aircraft plywood for strength and rigidity on 18" and larger cells and 1" thick, 22 layer on 16" and smaller cells.  These premium quality cells have a computer designed, 6061-T6 aluminum flotation system that utilizes 27 point flotation on 24" - 32" cells, 18 point flotation on 16" - 22" cells and 9 point flotation on the 10" - 15" cells.  The flotation points allow the primary to truly float, supporting it evenly and aiding in cooling.  This design approach thermally isolates the primary mirror and minimizes cool down time, especially on larger mirrors.  New to mirror cell design is our exclusive MTS (mirror transport system).  Just back down the collimation knobs and the mirror gently comes to rest on three cushioned transport pads.  All the collimation bolts are set in flush with the back of the mirror cell for a clean look.  Save 30-40% by assembling and finishing yourself.

While observing, your mirror stays accurately positioned from horizon to zenith with our fully adjustable, stainless steel sling, giving proper edge support with no sag or stretch.  Edge slings are the choice of opticians and professional observatories, giving the best resolution your optic is capable of producing.

All cells have precut mount positions for the fans and control plate to easily install the optional cooling system on the 10" - 22" cells.  The 24" - 32" cells have the cooling system as a standard feature.  It is highly recommended you purchase the cooling system if you observe from a site that has daytime to nighttime temperature changes of more than 20 degrees.

Assembly and finish is required

Cooling system is optional on 10" - 22" cells

AstroSystems computer designed Primary Mirror Cells are made from a frame of 1 inch thick, 22 ply aircraft plywood on the 10-16 inches and 1.4 inch thick, 26 layer aircraft plywood on 18 inches to 32 inches for strength and rigidity. These premium quality cells have a computer designed, 6061-T6 aluminum flotation system that utilizes 27 point flotation on 24inches to 32 inches cells, 18 point flotation on 16 inch to 22 inch cells and 9 point flotation on the 10 inch to 15 inch cells.
