I have decided to go down to one scope so I no longer need a dual mount.
This is an amazing mount that can take two decent-sized scopes. Includes power adapter.
I added the StarGPS to it and I'm including it with the sale.
The scope is a good Celestron 90mm f/14 focal ratio scope with a 25mm Plossl eyepoece. You can use it as your primary scope or as a secondary.
Here is info about the mount: https://agenaastro.com/meade-lx65-german-equatorial-mount-228000.html

Asking $700 (or best offer)
