There are five of us here with the ED72 - Nik, Rod, TrevorP, Martin_S and myself.
My next purchase is looking like the ZWO EAF, as I struggle to get the thing focused properly. (Have you noticed that the focus shifts slightly when you tighten the lock-screw?
Trying to focus incorrectly so the screw brings it back into focus is a nightmare.)
After that, maybe a dedicated OSC camera... After I rob a bank or something to pay for it.
Cheers,
V
