Tracking and guiding are worlds apart... with my setup I can push 4 minute exposures unguided provided I spend a good 2 or 3 hours drift aligning first, with guiding, I drift align for maybe 30 minutes, then take 25~30 min exposures...
Thats a great first shot, you wont know yourself when you get guiding going... When I finally got it working the first time I didnt stop smiling for a couple of days!
