Manual Focusing Aids for Precision Focusing

◄ The Digital Focus Counter (DFC) is a low-

cost mechanical alternative to the electronic

Digital Readout (DRO). The three-digit

counter display allows 10 turns of the shaft be-

fore returning to zero for focusing repeatabil-

ity on SCT focusing knobs. DFC is also avail-

able as a piggyback unit integrated into some

MOTOFOCUS units (see our website).

MicroFocus is a push-on two-speed manual

focus mechanism that attaches to the shaft of an

SCT focuser (or the knob itself) for precise focus-

ing. It includes separate knobs for coarse and

fine adjustments with a numeric dial indicator

for improved accuracy and repeatability. Mount-

ing is easy, with no need to remove the original

focusing mechanism. ►

What is an Ampere-Hour?

The Ampere (amp) is a unit of

measure of electrical current

(or flow). Batteries are often

measured in ampere-hours to

show the total amount of

electrical current capacity.

The easiest way to understand this rating is to remember that a

device drawing 1 amp from a fully charged 7 amp-hr battery will

run 7 hours. If the same battery was drained at 7 amps, it would

last about 1 hour. (amperage x hours = total amp-hrs used)
