Hi Alex,
My question concerns the positioning of a small electric heater band wrapped around the front-end to prevent dew formation. Is this what you mean by "dew cover" or do you mean the hood that I also use as a shield over the front of the scope (ie a lens hood).
Also I don't understand what you mean by a "baffle". Could you explain further please?
With regard to lenses, if I use a cheap Barlow then I might as well get cheap eps. Surely the ep will only be as good as its poorest component?
Unfortunately, in Melbourne, water is scarce and we have to conserve it to retain our green gardens as opposed to dust-bowls. We just don't get the rainfall you experience in north-central NSW. I'll just have to put up with a sore back from time to time.
