Still finding a use for the Tristand. I’ve missed out on a good nights observing tonight as the Q and everything were completely soaked with dew. Guess I’m gonna need the dreaded dew heater bands.

still incredibly impressed with the quality of the optics, especially with tight double stars. Such a pleasure to observe with.

Dew (actually, frost on the corrector) was a problem for me, especially since i like to observe in the cold.

 

This very old post of mine describes how I solved *my* problem -- it may give you some ideas:

And I thought the purpose of the white liquid hanging off the side of the Tristand was "antifreeze."  Doesn't that white liquid mess up your night vision??

I'm not sure I'm following . . . Are you liking it, or struggling to fit it into your routine?

It’s a very heavy piece of equipment but I’m loving it. If I had to reorder everything again I would definitely still include the Tristand.

Yeah, when the fog rolls in, it's time to go back inside and let the instrument dry off.  OR  stay outside,

 blow dry the dew shield with a hair dryer and keep an eyepiece in my pocket.  If the seeing is awesome, I will blow dry the meniscus with minimal heat in order to stay out longer.

 

I don't do all nighters anymore - 45 60 minutes so I don't need dew heaters, etc.

Yes I was thinking about the hair dryer treatment too. That or a handwarmer taped to the dewshield.

I also cover the scope with a small warm towel when I am not observing (the towel is inside my jacket otherwise) , 'would imagine there are better ways to reduce dew build up.
