Re: [APML] Guide scope alignment

[Alan Jones <ajonesmis@yahoo.com>]

Don,

I use the Megrez 80 piggyback on my 10" LX-200 for
wide-field imaging.  I use my ST-7 as the guider and
attach it to a Lumicon GEG to get a slightly shorter
focal length.  So far no problems.  One thing to watch
though is locking down the Megrez focusing tube. 
Towards the Zenith it will start to creep if you're
not careful.  And be generous with the counterweights
to keep the motors happy!
