power and firmware

Nicole and I chatted, via Facebook, and then by phone, on a few telescope matters.

She reported an issue with her current 2-year-old battery pack. The Eliminator doesn't seem to charge. Charge lasts only an hour or two. I said it was probably cooked. Guessed that the wall wart or the charging circuitry was not smart. Suggested a charging regime to try to bring it back. If it didn't rejuvenate, Dave or I could have a go at it.


She said she was thinking about the Nautilus from Canadian Tire. I recommended it highly. Marine technology, so better for our purposes. Heavy though. Expensive. But it went up for sale often, usually with 40 points, or $100, off. On sale this week, in fact!

I clarified that a SLA battery would be able to handle the amps, no trouble. Mount, dew heaters, and more.

She also asked about firmware updates for her Celestron hand controller, so to resolve the codes she was getting. I didn't think that was the issue. I wondered if the faults were due to low power. Urged her to try with the AC adapter. She didn't have one. OK, try running off the car. Or borrow a battery.
