Thanks to everyone for buying my spare stuff and helping me with the clean out. Here is another item that I'm not using.
For sale is a used GSO secondary mirror. I measure it as 87 mm x 123 mm.
Similar (perhaps identical?) to this, except they say 88mm. Perhaps they include the bevel?
could be useful for ATM project or if you want to upgrade to a bigger mirror. It's from my AT12IN
, I put in a slightly bigger one.
including postage in Australia.
No holder or anything else, just the actual mirror.

dated BEFORE Nov 2011 were taken with this mirror :-)
Edit: added a picture and dropped the price a bit
