Premium 10" F/6 mirror - Obsidian Optics - price drop
This is an excellent 10" F/6.1 mirror from Obsidian Optics. The substrate is 1" Pyrex so it cools very quickly and does not require a fan (assuming it is in a fairly open cell). These now cost AU $1,200 new.
There are a few blemishes on the coating which don't affect the image. I've tried to show the main one in the photo. I have adjusted the price to reflect this. This would make a great replacement for a GSO mirror.
$550 + split shipping. I will pack it very carefully.

Reason: Price drop & corrected substrate information
