Goodness, is there a mount under all that spaghetti?

So two straps - the blue one on the bottom end of the hood and the black one on the upper end of the tube?

Thanks!

Bill

That's right. On one night I had dew forming on the inside of the lens, that's why I have now two straps that gently heat up the areas in front and behind the lens, and use desiccant plug after each session.

I will one day tidy up the wires, (when I will build an obsy), but in spite of all the wires, it is actually very quick for setting up and packing up - it takes me only about 5 minutes to set up the telescope and perhaps 20 minutes to accurately polar align.

Sounds like a good idea - I had what looked like condensation inside the air gap last time I went out. I didn't like that!

little tip dont buy an expensive desiccant plug just find an old plastic film canister and put a couple holes in the end and grab some little desiccant packs off ebay for a couple bucks and put them in it and cap it off , it does exactly the same job
