The PowerTank Lithium keeps the charge going for the astronomer on the go. The Lithium Phosphate (LiFePO4) battery chemistry has significant advantages over other battery chemistries. The LiFePO4 can be charged and discharged 2000 times compared to only 500 for a Lithium Iron battery and 300 for sealed lead-acid designs.
These economical single axis (R.A.) DC motor drives are designed to compensate for the earth's rotation. Their rotation speed matches the earth's rotation rate for stars to appear stationary in telescope eyepieces. With a 9-volt alkaline battery (not included) installed, it lasts up to 40 hours.
The new HM5 Polar axis finder scope is a very useful accessory for the EQ5 Equatorial Mount. It speeds up and refines the polar alignment procedure so you can spend more valuable time observing, rather than setting up.
