Shouldn't matter. The absolute encoders always know where the mount is.I agree. I'll wait to hear from more knowledgeable persons but I have never unparked my Mach2 from any park position like I used to do with may AP900. I just set up the mount and initialize it in whatever position it happens to be in.
My setup routine is:
1. initialize the mount with APCC to one of my pre-set locations.
2. Do an initial alignment with the RAPAS.
3. Do another alignment with SharpCap.
4. Connect to TheSky and use TheSky to slew to a bright star. The star is always on the chip and pretty close to center.
5. Center the star with the crossharis in my image capture program and perform a Star Sync with TheSky.
That's it. A lot simpler that with my AP900 because the mount already has a good idea of where it is pointing. I just have to refine things a little after the polar alignment.
When I am done with the mount, I just turn it off. With the AP900 on multi night trips I would park the 900 in Park3 so the mount would know where it is on the next night. I don't have to do that with the Mach2. I just turn it off. I can loosen the clutches and re-balance when the mount is powered down and the Mach2 is dead-on when I start it back up.
