I understand its limited weight capacity but the portability factor is very appealing for me as i need to hike a bit for my viewing site. Would you be able for say 1 min tracking with 85 mm lens without polarscope?

[Re: ghataa]       #5608653 - 01/06/13 03:36 PM Edit   Reply   Quote Quick Reply   The Polarie manual states that pinpoint stars can be held for a 1 min. exposure at the celestial equator at 85 mm focal length with a 2 degree polar alignment error (assuming a .001 mm camera pixel size). If you think you can get less than a 2 degree error using their default finder window then yes, you can.
