Hi JG,

It looks like there is a lot of light lost by the grating. I see it is 217 l/mm. Is that the Baader grating ? I think they claimed a very high maximum efficiency (80% ?). Was the blaze in the right direction ?

Cheers

Hi Robin,

Yes, you're right, this 2" with 217 l/mm. transmission grating is from Baader. Really it was a pity that they discontinued it.

I don't find much difference of sensitivity between, the NOU_T, ( with prism F2, Nikon 85mm. and direct to telescope ), than the MUSSOL, ( with transmission grating, Ashai Pentax 85mm. and optical fiber ).

In that precedent comparation picture the NOU_T his been transformed in the NOU_58 with one Not-NIKKON 58mm. F1.2.

In the NOU_58 the theorical sensitivity, increasse more than 100%, but R, it's only 8500., you can choose..

Friendly, Joan.
