Re: [ap-gto] 600E PE "Normal"???

Hi folks,



I'm wondering if the result I'm seeing is "normal" with my recently

acquired 600E (while I wait for a 900 or Mach1 g>). I've uploaded

an Excel file to the Files section for those who might be able to

help.



PEMPro gave a +/- 25" error--which stunned me... It does seem that

the worm is running slow(?) for the majority of the run. Any ideas

as to what I'm seeing here?



The mount's carrying an 8" M806, Pyxis rotator, and ST8. Probably

right around 27 pounds--so probably overloading a bit, but I believe

it's pretty well balanced. Other than the PE concern, though, the

mount ran great last night and guided fairly well after programming

(was able to get it down to +/- 8", but need to run a few more curves

to refine--maybe I can get better).



Any thoughts/advice would be greatly appreciated!





Thanks,

Bob

Are you sure your parameters (focal length...) were OK?



In any case, your curve is smooth, so PEM should work fine with your mount,

much better than a small PE that shows sudden jumps.

Thanks, Gilles. Yea, programming did bring it down pretty well and the guider kept up with it rather well.



The scale was right (1.45"/pixel), so the data, I believe, is pretty accurate.



Take care,

Bob
