Quote:Glen,There's no polar alignment scope for either the CPCs or the older NexStar GPS scopes. Instead they rely on the software based polar alignment routines. You'll often hear folks referring to the ASPA (all star polar alignment), this is the software polar alignment routine.I have seen home brew wedge setups where a polar alignment scope was incorporated but for the Celestron scopes the firmware based polar alignment routines are very accurate and very convenient.
