Quote:Ok, i am reading the instructions on using the Celestron Polar Axis finderscope and have a question. I dont have the part in my hands yet so i am just reading the manual.
After you rotate RA to get Big Dipper or Cassiopiea near their etchings you are supposed to use the AZ and ALT knobs to move polaris "inside the small circle".
Is polaris supposed to be dead in the middle of the circle? The illustration show polaris on the edge of the circle.
Quote:The older versions of the HC firmware had the Polar Align function. The newer firmware gives the CG5 / ASGT the ASPA feature. If you have the older firmware, you should update to one of more recent versions. Also, the latest version of the CGEM HC / MC firmware gives you the option to change the slew / goto RA / DEC speeds from the default 9 setting, allowing these mounts to operate quieter. One thing to keep in mind about the PA scope, it needs to be accurately collimated before it's of any use.
Quote:So the new HC is worth the $150? Can i not physically polar align with the Polar Axis Finder then use the older HC to three star align? I have the patience to use it and i dont see a huge advantage of ASPA when i have a perfectly good view of Polaris.I will be guiding with PHD so i want my MC to be up to date with the latest firmware. So that is one upside to the updated HC.I really don't care how quite the motors are.
Quote:So the little circle on the center circle is where i need to stick polaris?
