Can anyone test a mounted secondary?
Hey guys,
I'm wondering if there's anyone local (I'm near Kilcoy, but greater Brisbane or Sunshine Coast would be ok) that has an optical flat that they could use (or lend to me so I could use it) to test a mounted (70mm) secondary? I'm a bit suspicious that my secondary has issues, perhaps in the mirror, perhaps due to its mounting (adhered to an aluminium stalk), but I'd really like to know for sure.
I'm considering buying a small flat myself, but they're a prohibitively expensive brand new and if I buy a second-hand one how would I know that it's actually flat?
The secondary was supposedly tested by the retailer (not the manufacturer) on their optical bench before I bought it, so I think it's likely that the mounting has deformed it. I may just re glue it myself, but I'd really prefer to (a) know that was the problem and (b) prove it's been corrected
Cheers,
Lee
