The "boys" over on CN in the Refractor forum sure would appreciate you doing that for them!  They surely would show a lot of gratitude. Hell one of them will even pay for your shipping and insurance....so I've read. In the mean time you can be busily working on your tube assembly. What do say? Are you game? :DMike |

Mike, For sure I am on game! it is an tempting Challenge, but for while I intend to enjoy the lens close to me  ,and build a great refractor, as it has to be done, for support this excellent objective. I prefer do optical tests on my own (as a professional astronomer/metrologist, why not?), doing beautiful astro-pics through this lens and showing the beautiful work lens that istar has been doing, Reading the posts here, its obvious that ISTAR is an excellent optical brand, I do not have doubts. Unfortunately, I do not understand a single word of german! And It is hard to have confidence in each site that supposedly show itself an expert... I should say only labs certified and people credentialed on optical fields can really attest. I recommed testing lenses in Institutes as NIST (or CALTECH), or kind of (it is expensive but worth your while, then you can shut mouth some people.. |
