The new Flash 4 Sky Commander transforms your telescope into an efficient observing tool. Locate and identify objects within seconds, even in light polluted skies. Spend valuable observing hours at the eyepiece instead of hunting objects. "Zero-in" the telescope to celestial objects. Just move the scope until the "difference reading" of the object you selected is zero. It's just that easy! Identify unknown objects in a real time search and identify mode. Any object within 0.5 degrees is identified and displayed instantly. Other features include 32 character super twist LCD information display with backlight dimmer control, battery monitor, magnitude filter. Best of all, the Flash 4 uses the simple, time tested two star alignment.

Complete with computer, 10,000 step encoders, custom made cables and mounting hardware.

9V battery operation
AstroSystems amazing Dew Guard secondary mirror heating system automatically senses the air temperature and the mirror temperature, then maintains the secondary at a preset (adjustable) temperature above the ambient air temperature. Gently warms the secondary at 2-4 watts when on full. The DG-1 has 4 evenly spaced contact points for optimal thermal distribution. Uses any external 9-15 volt dc supply or you can run on a 9v battery mounted at the holder, eliminating the need for wires across the spider. Note: 9V rechargeable NiCd or NiMH batteries will not work, they are only 7.2-8.4V and have low capacity, rechargeable Lithium cells are 9V and will function properly.

Mirror Cell Springs
Set of 3 springs with double the stiffness. Easy to replace and makes aligning the primary mirror smooth and accurate.
Package of 3 springs $5.00
Secondary Collimation Thumbscrews
Set of 3 collimation screws with thumb knobs. These adjustment screw knobs eliminate the need for a Phillipís head screwdriver to collimate the secondary mirror (which means you donít have to worry about dropping a screwdriver on your beautiful new primary mirror!). These black, fully threaded screws replace the recessed factory screws and extend the grip-point with a 1/2 inch diameter head to allow you to quickly and easily adjust the secondary mirror during collimation. The secondary mirror is suspended on thin metal spider-vanes which can flex under the pressure of a screwdriver, but with these thumbscrew knobs you can use a more precise, lighter touch during alignment, increasing collimation accuracy.

Safely awaiting dark
Effectively cover your Scope at star parties and in storage. This white, 400 denier, polyurethane coated nylon fabric will reflect the sun, resists dust and moisture and is long-lasting. Our cover allows positioning in the horizontal when not being used so that high winds won't knock them over. It has a draw cord at the bottom to give a snug fit around the bottom of the rockerbox. A sturdy 1" nylon strap is provided to attach a weight to the top end, keeping the wind from standing the scope up or turning it into a cosmic weathervane. The water and dust resistant polyurethane inner coating rounds out a complete protection package for extended observing sessions in the bush. The cover exterior is sprayed with a water repellant to add further protection from the elements. The Newtonian cover comes with a storage bag and secondary mirror cover, both with draw pulls. Worth every penny in strength, longevity and protection. The AstroSystems cover is not intended for continuous outdoor exposure. To retain the maximum water repellency, it is necessary to respray the cover once a year with silicone water repellant. A 12 oz. aerosol can will coat a Z12 cover 4-5 times.
