How much power does your telescope use

[jnb]

How about 10 GWh a year?!

Probably about 100 calories, 200 on a particularly cold night

Our push to mount uses one 9 volt battery to operate the Sky Commander computer.

The 7" Mak fork mount uses one 9 volt battery, which operates it for about forty hours.

The 3.5" Mak fork mount draws 3 watts per hour.

The 60mm class EQ mount draws 4.5 watts per hour.

Our Telescopes use no power, and neither do our manual mounts.

Depending on the length of time,usually a flask of sweet tea and a bar of chocolate

Hate to admit it, but I actually did a calculation for this!   Yes, I'm the one LOL. As I use a 12v marine battery to power my gear and am charging it via solar panels, I was curious as to how much power an all nighter imaging session would drink from my battery. I may as well share my calcs in case anyone out there finds it useful {long silence..}...

Power consumption in Amps: (times by 12 for Watts)

EQ6 (Parked)  0.50A

EQ6 (Tracking)  0.76A

EQ6 (Slewing @ 800x)  1.90A

Both Heater Strips  0.37A

1 heater Strip  0.14A

Camera (Exposure)  0.36A

Camera (Idle)  0.14A

I'll leave out all the math gumph, but in short it worked out that an 8 hour imaging session used 17Ah of power (6ah of which was the EQ6 tracking). One day I hope to include the laptop (I use AC for that at the mo).

Cheers
