Fantastic news, Markus Great to see samples coming through!

Question - is it supposed to say "APO" on the dewshield?

Thanks for sharing the news with us

Regards,

Its now 15 minutes past midnight, clouds rolling in, seeing is lousy, so I have to give up.

Last view in Jupiter with Leica Zoom at 135 looks perfect white , no yellowish casting or whatever. With 4.7 mm ethos , I can see at low jupiter the atmosphäric dispersion , but still white jupiter disc with all belts and stuff, but not worth to continue now

Maybe tomorrow morning , will see

good night

A first Test was performed by Mr. Rohr and a problem in the cell was found. The problem was reported to the manufacturer and they going to fix it. This problem can introduce a astigmatism, therefore this objective need the new reworked cell, which should be ready soon.

The spherical correction of the las was tested with 1/5.7 wavefront p.t.v., 1/29 wavefront RMS and 95.4 % Strehl...in summarize better I promote and offer.
in Double Pass sheme at 666 power Mr. Rohr found a astigmatism, maybe invisible at real sky, but not accepted by me, therefore we going to improve something on the cell.

Mr. Rohr:
This is the number of secondary spectrum, this means a normal ED-APO
Focusshift :
from green to blue 0.031 mm
from green to yellow 0.011 mm
from green to red 0.0200 mm

W-blue 0.4864
W-yellow: 0.1574
W-red:2.8613
W-total: 1.6739



Mr. Rohr recomment to increase spacing by 0.1 mm

Please accept that we not going to publish such a report, because we do not accept it this way. If w epublish it, some special people will use the published report to state it as a reference, which it will not be, since w enot going to sell it with this problem.

Of course I could be silent and answere to asking customers Mr. Rohr need more time, but w ehave been very open on this project from beginning on and we continue to be open and if the very first testing smaple show a problem, which we do not accept, then we say it and fix it, till we have the level, we need for selling.

We have big hopes that the new cell arrive before departure to USA to the Show next month in Tucson.

First summarize: colorcorrection and optical quality is better then we expected, the cell problem we get fixed.

The manufacturer know we not going to work on each single telescope to fix a problem for the serial production, so we push him to get it done right for the serial production and he cooperates very well so far and quickly.
