Quote:I read interested email exchanges on the refractor forum of my new China ED, beeing compared with others . I am wondering why nowhere in the world I can find a few reviews or open testst of such true apos. How can that european person compare something he has never seen and nobody knows how good it really is ?Anyway in a few days we have our first sample and in 4 weeks we shop it to the big new world in Tucson

Quote:the second sample was tested by a original twymann interferogram send to us.with all errors includet it turned out with 94.7 % strehl, not bad.Taking out a 1/5 wave astigmatism ( Mr. Rohr told me under sky its a invisible error ) the strehl would go up to 98.8% , wowMr. Rohr told me the optics in this condition we can sell without getting any complain :-)however I asked the manufacturer to tune a bit more on the astigmatism to come closer in result to the real quality of the glassee you this weekend in Tucson with the 152 ED live !!
"Considered as a collector of rare and precious things, the amateur astronomer has a great advantage over amateurs in other fields ... the amateur astronomer has access at all times to the original objects of his study; the masterworks of the heavens belong to him as much as to the great observatories of the world. And there is no privilege like that of being allowed to stand in the presence of the original." --Robert Burnham Jr, Burnham's Celestial Handbook

Quote:Lovely!Is that with the focuser rack all the way out?
Quote: He was very proud that, in his words, "The scope started as a discussion on Cloudy Nights in April, and here it is, in November, ready to buy. No one else in the industry does that."

Quote:Hi Guysafter a long flight I came back this morning to germany and did already a full day job :-), now reading here a bit and then its time for some hours sleep.The focuser on the pictures is not racked out much , but a 2" extension was addet to rich focuse on bright lights inside the big hall.To bad there was no good clear sky for a starparty to show its potential.Nobody took the chance to buy it, so its now on the way back to Germany and I will have it for showing at 24 november at our day of open house for european guys to look on it and through it.
