TeleGizmos solar radiant barrier material is a proprietary structure unlike any other scope cover material available. It is not Mylar. The internal aluminized radiant barrier is pure aluminum applied through a dispersion process that is accurately controlled for consistency. The fibrous webbing imbedded in our solar material creates a strong tear and stretch resistance foundation. All this is built into multiple layers of polyethylene.
The standard covers are for short term outside use and not intended for long term outside exposure. For long term outside exposure the 365 Series are required.
Cover sizes are inter-changeable. The correct cover size will depend on the scope set-up. For example, a fork mounted 8" SCT will use a TG08. A fork w/wedge mounted 8" SCT will require a TG12. To determine the best cover fit, measure the scope/mount set-up and compare with the stated cover sizes.

Truss Dob Covers for Horizontal Parking Position to 90 Degrees Down
Our 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.
We offer three standard sizes that where developed with the aid of several owners of large truss Dobs and the assistance of Roger Greenwood of AstroCrumb In most cases, our standard sizes will provide you with an excellent fit. However, because of modifications that many Dob owners perform, we can modify any of the standard size covers to meet a specific need. For example, we recently modified a TG5D cover for an owner who had added 10" of extra height to the base of his rocker. We added the extra 10" to a standard TGD5 and as a result was able to provide for his specific cover needs. We offer this service for very little extra cost, often at no charge if the modification is minor. Speak with your dealer or contact us direct for more information.
It is important that you check your scope dimensions to determine your specific size needs. Listed below are the standard cover specifications. Should you determine you need to measure, check the "What to Measure" page for a step by step guide with photos.

TGLB-12
TGLB-12 is specifically designed for the LightBridge 12" scope, dedicated horizontal park position.
TGLB-16H
The new TGLB-16H is specifically designed for the LightBridge 16" scope, dedicated horizontal park position.
Horizontal Park Position Cover for the Meade 10"-12" Light Bridge Dobs
We think the new Meade Light Bridge Dobsonian telescopes raise the bar to a new level in the small to mid-size Dob category. As such, we have developed a very unique dedicated cover design for the Light Bridge.
The TGLB-12 incorporates two main sections: A cylindrical truss section with adequate circumference to allow for clearance of the standard mounted finder. The rocker section is box shaped to provide full coverage and enough vertical height for total coverage around the rocker base. Double lap seams with micro stitching attach the these two main sections and provide high water penetration resistance. Combined with our solar material's water proof quality, you can be assured of complete rain protection.
Protection from rain is not the only key benefit of our covers. The radiant barrier effect of our material will protect the scope from harmful UV and heat build-up. This reduction of daytime temperature build in the scope will reduce scope cool down times. The TGLB-12: Outstanding protection for your scope. Currently available for the 12" model, covers for the 8" and 10" available soon.
TGTP Covers
The new TGTP tripod cover is a three panel cover that opens full length on one side. Once wrapped around your tripod, the open side of the cover seals shut with a full length Velcro fastening system. Heavy duty 1 inch welting is wrapped around the top and bottom of the cover. A 2" welting is used on the open seam and has the Velcro fastening system sewn on to it. Four 2 inch spring clamps are included for securing the cover to the lower part of the legs or elsewhere as needed. Used in conjunction with any TeleGizmos scope cover, you now can protect your entire system from top to bottom.
Additional uses:
Many users leave the cover on their tripod while observing or imaging if conditions are particularly dewy. The adjustable top opening allows the user to place the cover over the mount's motor drives and electronics, protecting these components from moisture. Accessory trays can still be accessed by opening the Velcro enough to reach inside the cover.
The TGTP fits all tripods with the following dimensions:
Leg spread up to 50 inches, leg height up to 52 inches. The maximum circumference of top opening with cover closed 27 inches (9 inch diameter). The top opening can be adjusted to a snug fit around the mount using a supplied 2 inch pony spring clamp. Three more 2" clamps are provided to aid in wrapping and securing the cover to the tripod legs.
Field Pack Covers
The new Field Pack Cover Series is designed to provide in-field dew control and protection for your scope's accessories. Their uses are numerous: Dew control for several styles of finders, temporary dew and dust protection for objectives, coverage of Telrad finder windows and more. Use the Field Pack system while observing, imaging or when you may have to step away from you scope. Pick a cover that best suits your needs. Or pick and choose any combination of covers. Developed with the assistance of noted visual observing expert David Elosser of North Carolina, these covers will prolong dew-free conditions for your equipment.
The TGBC will fit most binoviewers with eyepieces installed for prevention of dew and/or dust exposure. It includes a draw string closure. The TGRD slips easily on and off but remains in place during winding conditions. Using the TGRD will reduce dew build-up on red dot finders during observing or imaging sessions.
The TGFC Cover uses the same design as out TRG refractor cover series. It has a sloping top line with 2" end panels and a built in draw string to insure a proper fit. The TGDS Telrad Dew Shield is a boxed end design that is easily installed or removed over the Telrad window, but will stay in place in windy conditions. Both covers will effectively control dew build-up.
The TGQC will fit all refractors scopes up a 4" objective. Great for temporary, thermally stable coverage of the objective. The TGTR Telrad Cover is made out a highly water repellent canvas. Intended block dew build up on the entire Telrad finder it is also a great way to protect the sharp frame of a Telrad from coming in contact with other materials such as a full size TeleGizmos Cover.
If you're heading to the bush in search of dark skies, odds are you'll be taking a cooler along. The TGCC Cover will significantly increase the performance of your cooler by reducing the effects of day time heat on your cooler and by reducing the loss of cold air from the cooler. Field tested by several independent users, it does a great job of extending the life span of ice.
