Anyone know a good source for a dew shield for a newer C-90?
Thanks, Paul

Lowes. Get some of the plastic stuff used to help you dump leaves into a garbage bag. It curls naturally, and is perfect for making a dewshield. Want store bought or pretty? My ETX wears an Astrozap, and she is pretty happy with it. ;)

A 4 inch PCV pipe end cap with a large hole cut at the end works. Use a little sticky backed felt on the ID to provide a slip fit. This is what I did for a full aperture solar filter. It should work just as well as a dew shield without the solar film.

AStrozap maks one. It fits the Apex 90, sky-watcher mak 90, etc. search on Amazon or Scopestuff, or your optics dealer of choice.

I bought a dew shield from Kendrick years ago.

The selection is here:

IME, the best dew/light shields are made from black foam sheeting held together with strips of Velcro. Flock with vertical strips of ProtoStar to do it real good. Very light, very dark and will not drip dew like ABS plastic or metal.

I use heavy black hobby paper, folded in half and rolled into a tube, for my 14" SCT. It works great and should be just as good for a C90. And cheap to replace.

I have an expensive flocked Astrozap dew shield; but I can't use it. The 14" gets so nose-heavy that I can't balance it on a wedge. My paper dew shield has worked well for several years now.

Black foam sheeting will cost you about 50 cents more than black hobby paper and will last longer in dewy environments. :ubetcha: I guess not much dew out west?

Naw, not much.
Maybe I'll try the foam sheeting when the paper wears out.
