Guidescope calculation?
I have an 8” 2032mm focal length SCT and wanted to ask if there was some sort of calculation to work out a suitable guidescope for it.
I have the Celesteon Guidescope pack but is quite heavy for my setup so looking for something smaller. Current guidescope specs below.
Celestron Guidescope
Ap: 80mm
FL: 600mm
ZWO guidescope
Ap: 60mm
FL: 280mm
Would smaller focal length be suitable?
