This guidescope is a very versatile 60mm aperture 240mm focal, an f4 with a built-in helical focuser for precise focusing of potential guide stars.
It ensures that the main mirror accurately tracks the celestial body to be observed. I use this SV106 as a deluxe straight-through finder scope, but last nights of November, as I’m looking for the way I can realize a new idea, I tried it in astrophotography with an ASI120MC-S to understand in “pratical” how the camera is going to work with a field made by a 60/240 configuration.
So, in parallel with my usual set up made by EOS550d on WO Zenithstar 61, I added the ASI120 to the Svbony SV106 and made all guided by the super excellent mini guide scope ZWO 30/130mm with QHY5 camera.
All are useful results to better understand which gear I have to look at, thus I need to decide among WO Redcat/Astrocat or TS61EDPH.
