I've lurked on the site ever since I started in the astrophotography hobby, but have never posted. This seemed like the type of niche issue that you all would have some great input on, and I would appreciate ideas.
I recently picked up an 8" Skywatcher Quattro with the Skywatcher coma corrector, and I also recently moved to New England. I quickly learned how big of a deal dew is once I got here. And when I say dew I mean heavy dew. Like dripping wet, "I hope my camera/computer works after tonight" dew. I picked up a Pocket Power Box and a couple dew heater straps - a 4" one for my refractor and an 8" one for my newtonian primary. Unfortunately, while the 8" band is doing a good job taking care of my primary, I'm finding that the secondary and even the coma corrector are collecting some really gnarly dew as well. I've seen some Kendrick Astro dew heaters that look like they'll do the trick for my secondary, but I'm not sure what exactly I need to do for the coma corrector.
I was thinking of picking up a small 2" heater band to go around the exposed optic of the corrector, but there are some very specific constraints on size. Check out the image I attached for my issue. The band needs fit around the outer diameter of the corrector (51mm), but within the inner diameter of the focuser opening (60mm) and not be wider than 15mm so as not to protrude past the end of the corrector. Is anyone aware of any solutions that might fit this envelope?
