RE: Atik-16200 I re-read the specs (its not full-frame, diagonal is 35mm, not 42mm) and according to Francois at Shelyak, its older CCD technology which is inferior to what Christian tested for the ASI6200MM CMOS camera. Guess I'll acquire the ASI6200MM at some point, but putting the rest of the eSh...

To: Ernst,

vielen Dank!

To: Tom RE:"James, it looks as if OPT sell the ASI 6200MM for only $250 more than the Atik." I have a friend who can sell me his used atik-16200 for almost 1/2 that price so I'm VERY interested to know if it a suitable replacement. If I cant answer him in the next few days the deal is off....

I wonder if this would be a good sensor for the eShel:

I think I can buy this for considerably less that the ASI6200MM Cmos.

To: Pete, RE:"James, you have replaced the window in the Atik 414 for your Alpy. Did you see a significant improvement in performance?" I posted the specifications for the glass here: http://spectro-aras.com/forum/viewtopic.php?f=45&t=2461 Its hard to tell the difference, though with t...

Peter Velez: "I had best place a pre-order Olivier - looks like quite an instrument" I had that idea too, but my sudden acquisition of an eShel may put this off financially for awhile! I may retrofit my lhiresIII for UV with the modified Atik414ex camera; modified with Quartz window for be...

To: Christian,

Excellent advice on the CDK telescope and thanks for clarifying the optical plug type!

To: Tonis, RE:"I found a description from PlaneWave website how to remove the lens group that sits inside the primary mirror hole. It is possible, but I don't know if it is possible to use telescope without it..." I got this .pdf from PW over the weekend....looks like a fairly easy procedu...

To: Christian, ENGLISH: I'm trying to order the fiber optics (50/200 micron) lines from Thorlabs. They got back with me quickly, but the interface ends might or might not be compatibly with eShel or injection unit; see: "....FC/PC connectors use a narrow key ("Type R", 2mm width) for ...

To: Christian, RE:"Thanks James for the translation. I'll put a link on my page (the only problem... is the translation of echelle spectrograph by scale-type sppectrograph ! ;-))." Yes Google/Microsoft not perfect translations!.....if I my dad was still alive I'd have him translate since h...
