How do I - Dew Solutions

Well, the night started well but the Telrad dewed up after only about
30 minutes, the Finder after about an hour, and, when I checked the
main scope after about 2 hours, I found the corrector plate dewed. I
always use a dew shield but it wasn't enough tonight. I was ready,
willing, and able to continue but the optics were done for the night.
I packed it in. The telescope is still air drying downstairs before I
put it away.

I had considered a Kendrick Dew Heater and am now considering it
again. Are there any other options other than a dew heater and a dew
shield? Any thoughts would be appreciated.

A dew heater is the best and most aggressive solution. One could use a
blower (like a hair drier) and this works well, but this is only a part-time
solution, as in 10 or 15 minutes the dew is back.

Some alternatives:

1. Dew heater (most reasonable)

2. Hair dryer (works on finders, eyepiecs, telrads can corrector plates and is
cheap)

3 Newtonian (Newts do dew up on occasion but it is rare in comparison.)

4. Head for the mountains. It is rare that there is a dew problem up in the
Lagunas and they were pretty amazing last night, what with the naked eye comet
and the clear dark skies. (This is the best soluton, most expensive time wise
but worth it.)

Being basically lazy, I'll probably go with this option. I think
there are options for eyepiece heaters as well. Of course, all this
eats power...

Next weekend I'm off to TDS.
