hmmm..... do you think they have the same thing at China? I am going to China at the end of the year .... maybe can get it from the source :D Many China amateurs tried and failed, including the chairman of an astronomy club in Suzhou where the Synta factory is.

As far as I know, there are several mainland China amateurs who are using the best quality APOs. What they did is to purchase the TMB triplet apo lens cell or a new "four element" super apo lens cell from Russia, then they sent them to a DIYer, an ex-staff from a machine gun factory for fi...

Are u refering to the 32mm PL ep? I bought it several months ago from harlequin at S$100, used only for few times. The invoice only indicates "super plossl (taiwan)", but the quality is good, you can test it on your scope before you buy.
I live in clementi, can accept cash or ATM transfer.

Review from an experienced amateur (quoted from yahoo group): "Color correction is obviously much better than the MII doublet was, looks like a solid ED-class performer. Not zero color like the much more expensive zero-color fluorite triplets, but at half the price, something of a bargain. Most...

My review on W/O yahoo group: “Kept my old Megrez 80II tube and bought the new ED triplet lens (F/7) from WO, a two inch extender tube is needed to provide enough back focus. The service of WO is quite good and speedy. 1. the lens coating is much better than my old megrez 80 II, the reflection is sa...
