I recently swapped some equipment for a used Orion Sirius EQ-G mount.
The mount's hand controller was missing
But I discovered the EQMOD project and with their help I had the mount responding to slew commands directly from a laptop - with Cartes du Ciel installed.
Firstly, I'm a visual observer and I found even with Cartes du Ciel in night mode - the laptop screen really messed up my night vision.
That is not going to be a workable solution!
Additionally I've been an AZ mount user for a couple of years - and I found myself making the wrong adjustments constantly trying to get the scope centered on an object. I think when I look at the sky - I'm going to have to imagine the celestial DEC and RA lines in the sky - and learn to move the mount axis in accordance to those lines.
I'm a visual observer only - so I'm wondering if an EQ mount is simply overkill and unnecessary complexity - and therefore I don't find it enjoyable to use.
