Thought I'd re-do the polar alignment on the G11. Last time I used Pempro, it was easy as, and took maybe 45 minutes. Now over three nights and hours of frustration, I can't get my head around whats going on.
These graphs show the DEC drift plotted in 5 second intervals. They all start off erratic, then level out, then erratic again, in a very periodic way? I unplugged the DEC motor just in case, but no change. I have checked balance, binding, end play, cables, no wind, and the seeing was good.
Even the star image in Maxim was jumping up and down between exposures. Im not sure if I was imagining things or not, but I ended the Pempro session, and did a 5 second continuous exposure and watched the star movement, and it was very steady. As if the software was messing with something, but I don't know how as the DEC cable was unplugged! Thats crazy right
I think I was going insane at this point
It looks to me like really bad seeing with the up and down spikes, but it's strange how it has these nice and smooth periods.
Last time I used this method I got pretty smooth linear plots, nothing like this?
I popped in a reticle eye piece and a 2x barlow for a manual go at it.
Any thoughts?
