Anyone owns a 12" or larger DOB?

Here is the place to talk about all those equipment(Telescope, Mounts, Eyepieces, etc...) you have. Not sure which scope/eyepiece is best for you? Trash it out here!

Hi,

Arief indicate it as 63" f/4. So focal length will be 63*4= 252" or 640cm. So the scope should be at least 5.5m tall.

Have a nice day.

Look at the size of that eyepiece holder! Either he uses a 6" eyepiece, or this photo is a blown up from a smaller version. And why bother with the tiny stool? There should be a ladder somewhere!

I think he use the stool, so that he don't look too short among the taller guys in the picture... ha ha ha :P :P :P
