1)The v700 gives the read-out in 5 degree increments. IMHO, this is not enough. I believe the v7000 unit has both critical components, namely the ability to correct for magnetic declination, as well as, giving read-outs in one (1) degree increments. There could be other units out there that have those same capabilites without the other bells and whistles for cheaper - I'm not sure.

2)I don't have the ability to post pictures right now.

Basically I screwed the compass into the swivel base board (toward the rear-end of the scope and directly opposite the front of the scope with the handle). If you can imagine placing the degree circle on the base board with zero (0) in the front - the compass would be screwed into EXACTLY where the 180 degree mark would be in the back. The compass should be screwed in tightly to the base. According to the instructions you can tilt the unit up or down within it's swivel bracket a maximum of 20 degrees but I found that not having a tilt at all is most accurate. Whatever angle you select for the tilt, the compass must stay that way (otherwise you'll have to recalibrate), thus I also tightened the side adjustment screw for the angle of the tilt so it doesn't accidently get bumped out of it's bracket.

3)The inclinometer was purchased at Home Depot (you won't find it on their website). It is an "EMPIRE magnetic polycast protractor" that can be purchased for a little less than $9.

I do not need to set North to Polaris - North is set magnetically by the compass and adjusted for magnetic declination. Once I turn on the compass and calibrate it (by pressing a button and spinning it in place one full revolution), I'm set to slew the scope to the coordinates I get from my planetarium software.
