I've been wanting to keep my ED80 setup in the obsy but the one thing stopping me was the worry about mould growing on the optics
One solution was to buy a desiccant cap for refractors, these look rather nice but are rather expensive for what they actually consist off which is simply a container with desiccant in which attaches to your scope via a 1.25-2" nose piece.
My solution isn't anything fancy but it costs peunuts and should work just as well, although yet to be tested
Basically I ordered 100x 1gram bags of Silica gel desiccant from Flea bay which cost me less than a pint of bear!
I then had a bit of a rummage around for any adaptor that fitted the focuser of my ED80.
I blanked off one end (Mine had a dust cap so I secured this in place with some double sided tape).
I placed about 10x 1 gram bags of the desiccant into the bottom of the 2" adaptor which was now blanked off, and secured them in place with a bit of tape so they wouldn't tip into the optics if the scope was turned upside down for some reason. Thats pretty much it!
I did go one step further and secured a desiccant bag inside the lens cap with double sided tape, so now either side of the lens cell should be protected from mould.
I think I'm now happy to leave the scope setup and see how it goes? I'll report back .
