My experience from my observation site in the soyth east corner of Norway is that the seeing is quite often bad, makin collimation "on screen" quite difficult, because the airy disk pattern on screen is difficult to "read".

Ornulf, use metaguide with Peak stacking method, 20 frame stacking (10 is default, 20 allows better collimation in fair seeing). If bad seeing dont bother, but I can collimate on 50% of nights instead of only being able to do so on the so far non existant perfect seeing nights.
Infrared filter makes it even easier.
So far every time I have collimated except for a good seeing night, has been with the Airy disk destroyed by seeing. Metaguide works wonders!
