*New* Now supplied with a 110v float charger to allow continuous charging without fear of overcharge. Eliminates battery loss due to the batteries staying undercharged for long periods of time.
The Cooling Fan Power Supply can be used with any 12V dc cooling fan(s). The power control will operate the fan(s) with an on/off switch, charge the batteries with either 110V ac (household) or 12 V dc (auto) and indicate that the batteries are charging with an LED indicator. Complete with control panel and battery mounting hardware. The system uses two 6V batteries wired in series to obtain 12V. The 3 amp hour batteries have plenty of capacity to operate 2 fans for 2-3 days before recharging. A higher capacity 7 Ahr battery is available for more than 2 fans or to supply other devices such as digital setting circles, dew removal or illuminated finders. It is recommended that the total power needs in amps be 25%-50% of the battery rating.
Battery dimensions:
1.3 Ahr 2" tall, 5.25" wide and 1.3" thick 11 oz. each battery (fits 12.5" - 15")
3 Ahr 2.5" tall, 5.25" wide and 1.3" thick 1.5 pounds each battery (fits 15" - 25")

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. The Sky Commander has an extensive 15,000 object data base upgradeable to 30,000, including NGC, Messier, UGC, IC, planets and 60 programmable objects. Complete with computer, 10,000 step encoders, custom made cables and truss telescope mounting hardware, (drilled azimuth pivot is required).
The Flash 4 Sky Commander is supplied with a computer interface cable for free downloads from the Sky Comm web site.
