Hi Vanda! I do it by hand with a Canon 400D piggybacked on a cheap, 'home-built' 80mm refractor, using the slo-mo knob on an EQ1 mount. But I don't use a reticle - just a cheap webcam in the refractor so I can keep a star still on a laptop screen. The EQ1 is very flimsy and the 'guiding' has to be done with
extreme care or the star flies around everywhere. It does have one advantage in that you only need to turn the RA knob (excruciatingly slowly!). Any slight Dec drift over 3 or four minutes can be corrected with a gentle pull one way or another on the knob. Set-up is attached below - I brace myself on the ladder to reduce additional 'wobble'.
One problem is the limit of your wrist flexibility. 2 minutes is OK, but it gets harder from there - 5 mins is the maximum I've gone. Mind you, I can't change grip once I've started or the star goes ballistic. With a solid mount it mightn't be a problem.
If you have a solid mount, you won't have any problems guiding a widefield shot through either a webcam or reticle, but I'd suggest that it would be a good idea to do a decent polar alignment so that you don't have to tweak the Dec knob (or maybe it's just that I can't do two things at once!
)
