Hi Rastis. I have a sweet little setup for viewing with refractors. I use the 80ED and Celestron EQ102-HD in a side by side setup. I can view nice widefield with the 80 with say a 32mm eyepiece and if I spot something interesting I can simply move my head to the side and view it at higher mag in the 4" with say a 2X barlow and whatever eyepiece I need. Or mix and match as desired. I normally use a Losmandy GM-8 mount but I've had success using an EQ3 mount (in the over under position, not as user friendly though. Plus it gets the shakes a bit at times
)
