Very impressive eyepiece box heater Rajah 235!
In relation to your comments about power packs, Louie, I found that when I checked my two new 17ah SuperCheap Auto packs the day after the April Starparty the batteries were only half empty. Pretty weird given that the battery powering the Orion dewzapper had an empty reading at the end of the night. I wonder if maybe the meter is just unreliable, and they are didn't drain nearly as much as it seemed.
What did your battery read the next day before you recharged it?
