The 12" shortens over half a meter. If I remember correctly. mine is just under a meter collapsed. Its expanded length is about 1.5 meters. Personally opinion. I think the focuser was bad - the single speed one. I had to remove the focuser tube and grind the surface that contacts the crayford-style focuser wheel with an oil stone because it was rounded and making poor contact. I got a lot of slippage before that. It is also very high profile compared to other designs. I recently after 3.5 years replaced it with a GSO 2 speed focuser. With how cheap that GSO focuser is. I couldn't be happier with the results. No slippage even with nearly 2 kilo's in the focuser. Also, with an enlarged 10:1 microfocuser wheel, fine focus is as smooth as silk.
