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..
