A little bit of pier help......

[stampy10000]

Hi

Over the summer months I'm hoping to convert my Orion Optics 12" dob for use on a pier with a suitable EQ mount (not decided on the mount, currently leaning towards old and heavy duty).

Eventually I would like to house the whole set up in a roll off roof observatory of some kind but without knowing the final dimensions required, I'd prefer to build the pier, get the tube mounted, then work out how big the obs needs to be!

My question is, how tall should the pier be to be able to still put the eyepiece at a useable height (the tube is about 5.5 feet long).

Has anyone done this themselves with a 12" f5.3 OTA?

Thanks
