Hi Raymo, I may have a bit of a suggestion to get you up and imaging in a shorter time. This method works for me, I call it the "poor mans" pier.
I have 3 steel right angle brackets purchased at Bunnings
http://www.bunnings.com.au/angle-bra...g0100_p3961276
These have 2 holes drilled on each face which are large enoughfor the tips of the tripod legs to go through.
I did a fairly rough alignment of the mount, got it level and then bashed the angle brackets into the lawn so that the tripod tips sit securely in the holes in the bracket. You just have to mark which holes you are using. Setup your scope and using what ever method you are comfortable with, spend enough time drift aligning until you are satisfied that it is very close - I had never drift aligned before so it took me a couple of hours with the illuminated reticule eyepiece to get it right. Now all I do is keep the tripod and mount assembled and move it out to my brackets and plug the legs into the marked holes and I'm polar aligned.
Now if the tripod and mount together is too heavy ( I always remove the counterweights first), you can remove the mount from the tripod by marking the azimuth knobs with a line pointing straight up and undo then both 3 turns counterclockwise - remove the mount and when you reassemble it just remember to turn the knobs 3 turns clockwise and you're in business!
It really saves me time - I just set up the gear in the late afternoon and go out when its dark and i am imaging within a fairly short space of time.
Cheers,
Bruce.
