Pulsar Dome - degrees out after calibration
Hi Group,
Having complete the installation of my Pulsar Dome observatory and have the drive automation unit installed and program as well, I managed to calibrate the drive after changing magnet so that the encode could read it better and after a single rotation it was calibrated. I am using both Park and the Home position at the same angle of zero degrees (basically pointing polarize). The dome shutter window center points to Polaris (already done a polar alignment), so my mount is at zero degree before I started the calibration.
However when the calibration was completed the drive panel screen showed 358 degrees and is spot-on the center of the shutter window, if I instruct the dome to move at zero/360 degrees it will move away from the shutter center.
When I originally installed the Drive and the encode I am pretty sure that I place the encode wheel to zero degree and the shutter window was centered to the mount/telescope position.
So, the question is, does it matter being a few degree out when I eventually slew to a target, or I can compensate somehow when setting up the Slave parameters, say on the North offset.
Any suggestion will be appreciated.
