Interesting thread... I've gone from a GP-DX to a Titan. Considerable leap in both capacity and capabilities. Due the possibility of moving OS for a few years, I'll probably downsize to a G-11, AP600 or EM-200 for some portable imaging in the northern hemisphere. No intentions to sell the Titan yet - may set it up for robotic operations while OS. If I stay in AU, then will probably invest into some quality optics to match the Titan's abilities. The humble C11 seems a waste on such a mount.
