Power Supplies

Depending on how much equipment you are carrying into the field, you may have several different power sources. Many small rechargeable batteries are of the nickel-cadmium type. Remember that to get the best endurance and voltage out of a ni-cad, you need to be a little nasty to it. Make certain that you run all your rechargeable nickel-cadmium batteries down to exhaustion. Remember that dirty or rusty contacts do not transmit electricity so keep them clean periodically. Cold temperatures can also cause voltage loss. To preserve the charge of the batteries, keep them in a warm place as much as possible. Sub-freezing temperatures can cause you as much as a full volt out of the battery's charge. Lead acid batteries in particular need to be kept out of the cold.

To get the best performance from your telescope,brain and eyes everything must always be kept in as close to pristine condition as possible. Keep all your lenses and eyepieces meticulously clean and scratch free. Make certain that your mountings are kept tight and secure so as to minimize vibrations. Make sure that your computer hardware and software are both properly maintained and that your batteries are ready to deliver the juice. Lets head out into the field and get to work.
