Cheers Mark, and yes, I can tell you about focusing, no worries, & beleive it or not, I just focused on a bright star before hand and locked it
Though I feel thats not all that needs to be applied for a sharpísh capture , , Its very much like capturing a bird in flight, or a racing car Etc, whereas you need to be able to follow the ISS smoothly enough for a crisp result, I think this is as much critical as focus, if not more
please read my other replys below for further details
cheers .

Hi Dave, and thanx mate , , ! well, I just chased it by hand hey, better control I think, interesting about the clutches, yes, I did release them as did last months effort, but actually found it a bit too free, so to speak, I did actually practice a few times on the mount and found if the clutches had a small amount of tension on them, then this resulted with better hand controll, I mean, one can apply a firmer steadier hand to swinging the scope around and once have the ISS in the cross hairs, then would find it wouldnt just slip out of sight as easily, therfor the following motion was steadier when in the sights, anyway, thats what I found
hope this is helpful, cheers !

Hi Ed & Thanx for your comment. I must say, it not all easy, as mentioned above, I actually practice the physical motion a half doz times before hand, Lol, bit like dancing with the wifey
Like in the ol' days, when you had to support the girl
funny thing tho, Im no John Travolta
All the best . .
