Pls PM me ur offer. Thanks!

why? we already proved that TMB Supermonocentric is better, from A-B test on Jupiter through 203APO.

Yes, I know. As my refractors are short focal lengths, short focal length EPs are suitable for me. u only sold me the TMB 4mm, but not the 5mm. I need to find substitutes for that. Do u remember once u told me Markus got a Pentax XO 2.5mm in his EP box? It means that Pentax shouldn't be bad. Not the best, but should be excellent.

This one is ridiculously high!

He had different eyepieces for different reason, e.g., he had Televue Radians for casual viewing, especially when he is tired after work,

So he got Pentax XO in the box doesn't means he rated that higher than TMB Supermonocentric.

I know TMB Supermono is no doubt better than Pentax XO. But
1. TMB has no focal length shorter than 4mm. So it is appropriate to buy XO 2.5mm
2. You don't sell me the TMB 5mm. It is almost hopeless to get one. I know there were some people bought Pentax XO in HK during the Mars conjunction years ago. So the chance to get Pentax is higher.

Anyway, if u sell me the TMB 5mm, the problem is solved.....

I had been telling you to get some TMB Supermonocentrics since you took the 105APO from me, now I have only very last few ones, for big APO owners (8" and up), so don't blame me on this.

you can always look for used Mono 5 from used market overseas, definitely cheaper than the Pentax one on ebay as posted by Oldfield.

I am not blaming u. Anyway, to get TMB Supermono is kind of fate now. I don't expect much on getting a TMB 5mm. So Pentax XO 5mm is easier. The ultimately goal is to get two for bino-viewing. Luckily, I got one brand new Pentax XO 2.5 from Japan auction and one brand new TMB 1.8X from eBay recently. These two probably the last brand new antiques in the market. If I can get two of each, I can have ultimate binoview....

you think at f/6.2, your scope have enough light gathering power for splitting the light into binoviewer and observing through path corrector of at least 1.25x & 5mm eyepieces?

Ha! Ha! For moon, perhaps Jupiter
