18769 Car Battery Adapter by Celestron

The hobby of amateur astronomy frequently takes the observer away from sources of AC power. After all, we are always in pursuit of the darkest skies possible, and that often means going off the grid. The most common way to power your telescope in these situations is to use a portable 12V battery pack, like the Celestron PowerTank, or to use power from your car's battery via the cigarette lighter.

The Celestron Car Battery Adapter is the accessory required for connecting any Celestron computerized telescope to a DC power supply or car battery. Plug the round post into the 12V input jack on the drive base of your telescope*, and insert the power connector into the cigarette lighter outlet in your car or on your power supply. The cord is 25 feet long, giving you plenty of reach between your telescope and 12V power source.

The barrel connector can be sued with any telescope that uses a receptacle with an outside diameter of 5.5mm and an inner diameter of 2.1mm and a "tip positive" polarity.

• Power your Celestron computerized telescope from your car battery or a portable 12V DC power supply.
• Barrel connector plugs into the 12V input jack on the telescope drive base.
• Power connector fits standard automobile cigarette lighter receptacles, also found on portable 12V battery packs like the Celestron PowerTank.
• 25-foot cord for lots of reach.

For use with the following telescopes:

• NexStar SLT Series
• NexStar GT Series
• CGEM Series
• CGEM DX Series
• CGE Pro Series
• CPC Series
• CPC Deluxe Series
• Advanced GT Series
• Advanced VX Series

67441 GT-44 Portable Gas Detector c/w Case and Accessories - ppm / LEL / GAS by GMI

Designed for the gas industry, the GT Series are multi-application instruments, satisfying all the needs of service technicians within a single unit. With 7 modes of operation, the GT Series is the most versatile instrument available for working with gas.

The GT 40 series offers technicians and workers a single instrument that can be used throughout the gas distribution and transmission pipelines for all measurements needed for leak testing, and confined space entry. Bright LED alarm lights illuminate as gas levels increase, and audible alarms are activated at preset levels should they be programmed. Completely programmable, the GT is an industry standard throughout the Americas and Europe and allows companies to utilize only one instrument for all their monitoring needs. The GT series is available with an optional docking station for full calibration and testing capabilities, and printed cal certificates if needed.
