>>> is this amount of drift considered to be too much ? The scale is + 20 arc sec, so I estimate about 1 arc second per minute drift in both RA and Dec.
if you image for 10 minute subs, that would be 10 arcsec drift, or 10 pixels if you had an example image scale of 1"/pix
so your stars would smear by 10 pixels. I would say that's far too much
Doing unguided with just visual polar alignment would be really tough. Using APPM and a sky model would help considerably for tracking improvements that compensated for polar misalignment
