No. They put different CCD's in different Grasshopper models, just like the Scorpions, Fleas etc.. The one I have (GRAS-14S5M-C) is 6.45 microns and it's an EXHAD CCD not a HAD (use Google to find the difference). Basically it means the CCD is about 3 times as sensitive as your 4.4 micron Scorpion is.
As far as filters go, I don't have a preference, except that they should be parfocal. I got a good deal on the Astro Don E series as they were being cleared out and were basically the same price as a Baader.
HTH..

Hi Milton,
I thought I read that your Grasshopper is 4.4 microns too, is this the
case? I guess there maybe other versions? I told the guy from Adelaide
I`d get back to him with respect to the Astrodon`s but not at his
exhorbitant price! Kurt`s just written with qualified praise for the
Baader`s for their price. Do you think they`d be better than your run-
of the -mill types like perhaps the Astonomicks, or any good at all?
