I am trying to pick my first guidescope and have no real experience in connecting and operating one. After looking at several models I am leaning towards a 60mm to pair up with my first refractor (ES ED102 CF). After a few searches several brands pop up in comparison to the Orion 60mm. The links below are just a few examples. Looking at the photos they all look like the same scope IMHO and can't tell if there are quality issues with lower priced offerings.
Orion 60mm F4
Solomark F60 60mm F3.4
Another possible for a guidescope would be the ZWO 60mm
On a different note figuring out what I will need to mount it on the ES ED102 CF. A 7" Los Mandy dovetail bar to replace the top handle and a ZWO ASI290MM monochrome camera as a guide camera. Telescope, guidescope and camera will be ordered after I figure it all out. Comments welcomed.
