   Date:    03062012

   Equipment:   LX200 GPS 8": various eyepieces, 2x Barlow, and a 2"UWF 24mm eyepiece.

Observations:   Mars: polar ice cap and how the planet laid on it's polar axis.

 Conclusions:   Need to calibrate the telescopes' sensors, even though, I had a successful alinement,
              (Mizar was hidden by a tree), and goto's were not that accurate, some being in the finder scope, and
              some not. None were in the telescopes FOV.

Hi Kip....more important than calibrating sensors will be the Train Drive function, which can - and should - be done in daylight on a very distant terrestrial landmakr (water tower, distant buildiing top, etc.) at very high power, making sure the target is dead center with each slew in each axis.

Takes only a few minutes and will improve your pointing accuracy greatly.

As one who has known and Doc and taken his advice for over a decade I can attest to it being akin to gold! I have never gotten one bit of advice from him that ever steered me wrong and I still rely on him a great deal.

Dear Dr. Clay and lindendave,

As one who has known and Doc and taken his advice for over a decade I can attest to it being akin to gold! I have never gotten one bit of advice from him that ever steered me wrong and I still rely on him a great deal.

Not hard to take when you realize it's born from one's passion.

Hi Kip....more important than calibrating sensors will be the Train Drive function, which can - and should - be done in daylight on a very distant terrestrial landmakr (water tower, distant buildiing top, etc.) at very high power, making sure the target is dead center with each slew in each axis.

I'll train the drives next opportunity.

Thanks for the feedback and your time too.
