Hi Dunk, As you may know, I 've been in this game a very long time, and
know my way around drift aligning, and I keep my cone error negligible
by checking it from time to time. It's the Go To era that has stumped me.
My problem is it seems to me that a star alignment followed by a drift alignment is doomed to failure. Any adjustment made to either axis
during a drift align immediately negates all the work put in to get a
decent star alignment. On top of that, if a single star align is attempted
at the end, and the target is found to be outside a low power EP F.O.V.
any adjustment made to bring it back into the field will also stuff up the
polar alignment.
I followed Billdan's suggestions to the letter last night three times.
Each time, after rebooting, a further 2star align ruined the polar alignment. I tried checking the 2 star alignment after doing a drift align, and it was a mile out, as I expected it would be.
On all three tests the target ended up way outside the F.O.V. of my
lowest power EP [40mm]. It's a bit like the uncertainty principle; I can
have great P.A. or great Go To, but not both.
