For sale is this beautiful doublet lens in excellent condition. The reason for selling is that I have another 5" telescope. This lens is exactly the same as advertised
here for $665 US plus postage (total about $800 AUD).
The price is $550 AUD including postage in Australia. I am in Perth if you want to pick it up in person ($25 discount if you pick it up).
Please send a PM if you are interested.
