That Power Supply For the Telescopes

I originally figured that whatever current that cute little LED voltmeter drew was not enough to worry about.  Voltage was dropping, although not very quickly.  Perhaps 0.1V per week?  So with a little help from my friend Willy, I added a push button in the circuit that feeds the LED.  Now it only shows voltage when I push the button.
