damn dew (Union)

My eyepiece dewed up!

There's a good chance I would have been successful with tonight's asteroid occultation, 95 Arethusa. But the 18mm eyepiece started to dew up leading up to the 2:55 prediction. And I didn't know what to do...

Guy was successful. I phoned him on his mobile. I could tell by his tone that he had nailed it. He captured good video of an 8 second event.

He said that I fell victim to Murphy's Law. But again, I'm not as inclined to say that. My 2" Kendrick eyepiece dew heater failed some time ago. I've been trying to make a replacement. But I still don't have the correct bits. The new nichrome wire I most recently purchased is not the correct resistance.

This just shows that I should have escalated this job. I should have replaced, or bought new, the dew heater by now.

It's a critical piece of equipment in these activities.

Lessons learned:
  • have all dew prevention gear installed and ready
  • have an eyepiece in a pocket, warmed
  • have an eyeglasses microfiber cloth at the ready
  • have a completed, working "anti-dew pad" built, tested, plugged in!
  • if near an AC power source, have a hair dryer handy
  • have a medium-sized cloth that the radio and recorder can both sit on and be covered by
Man, there's a lot of stuff you have to do...
