114mm f/4.4 or 125/130mm f/5 parabolic mirror

Hi all,

Having another go at finding a 114mm f/4.4 or a 125/130mm f/5 parabolic primary mirror.

So far everything I've seen here in Oz have been all spherical mirrors, despite the advertising spin from the manufacturer saying "parabolic". Only exception was a Vixen OTA that i came so close to buying, but I couldn't bring myself to cannibalize the mirror from that lovely OTA. I'm still hopeful someone does have a parabolic mirror in the size I'm after. May well have to resort to cannibalism otherwise...

May even consider a 150mm f/4 parabolic.

Thanks for looking,

Alex.

Ok, I'm prepared to go bad and cannibalize a Vixen 130sf OTA if I need to...

Oh the pain, the torture, the eternal damnation of tasting The Flesh... Don't look at me, I'm unclean...

How about an OTA of the size I'm after with a parabolic mirror since I'm willing to take a Vixen OTA?
