TeleGizmos Standard Dobsonian Covers.
The TeleGizmos Cover is a multi-layer, polyethylene material with a fully aluminized surface. The heat reflective ability of the cover is extremely high with a material strength equal to a multi-layer light weight tarp.
The material was originally developed for NASA as an insulator in spacecraft. It is very strong, light, tear and puncture resistant and is highly superior to Mylar in durability.
The benefits of the covers are numerous:
TG1D - TG4D. For vertical to 60 degree down park position. These covers are capable of fitting several other scope sizes. Check your set-up dimensions and reference the stated cover measurements to determine if a cover will fit systems other than those listed.
TG5D - TG7D. For horizontal parking position to 90 degrees down. Large truss Dob Cover series offer large Dob owners the best possible protection available in a scope cover. They provide superior rain and moister protection; they are not just water resistant. They are extremely tough and can provide years of service under normal use.
The TeleGizmos material performance is unaffected by wind, sun, sub-freezing temperatures or UV. The fully aluminized/poly exterior surface will keep your scope significantly cooler on hot summer days translating into much faster cool down times once the sun sets.
Designed to give the best possible fit, these covers have two main connected components: The main tube section is four connected tapered panels, the narrowest point starting at the UTA and then gradually widening to the point of attachment at the rocker box. The rocker section of the cover is boxed shape to conform the general shape of the rocker. All connection seam points are double lapped and micro-stitched. The resulting seam is highly resistant to moister penetration to assure your scope will stay dry under even the hardest rains.
