HAHA ...
1. As far as I know, the APOgrade is available cos WO made/ordered/whatever a whole bunch of extra lens cell when they were producing the Anniversary scope so they're selling the same cells as an upgrade. With the focuser upgrade, it's pretty much the same other than the limited edition factor and the red tube.
2. HAHA .. Arief got me on this one, but I;m not gonna sign a contract!! HAHA .. But well, one of the things we talked about was that I will put this scope to good use, so I will. No point saying I will put it to good use and selling it before I even touch it .. HAHA ...
3. There has been a big debate over this one, and as far as I know and have read, Thomas Back has more than once asked William Yang to remove his name from this particular lens design in at least 2 forums. I do have imaging in mind so I guess the triplet will do well here.
4. The part about LiuMing's club is only a joke lah brother!!

But it's true that I spoke to Liuming before about APOs and just after a short while, he had me convinced about TMB refractors. I even told him TMB is now my dream scope .. HAHA ..

Look at it this way, from my very limited knowledge, in Singastro at least, there are quite a few Mewlons and perhaps a couple or more Zambutos. Not many TMBs though, especially DIY ones ... hee hee ..
HAHA, anyway, at the end of the day, all this is is all for fun eh ..

Let me know if the 4&5mm come loose from the set .. Hee hee ..
