Set up in the field takes 5-10 minutes. You attach the OTA to the

was
the
bracket for mounting the OTA. The tube on my TV85 is smaller than

the
90
mm diameter tube on the Celestron OTA that came with the mount, so

it

made sense to use the existing bracket with a step-up adapter.

The celestron bracket is a clamshell design where one side is

hinged
so
it can open to accept the OTA. A single brass thumbscrew locks the
bracket around the tube, so it's fairly easy to do, even in the

dark.
I
made an adapter from a block of delrin to step up the diameter of

the

TV85 to 90 mm. You can also buy a slick, ready-made part from

Baader

It's adaptable to several different OTAs. If your Tak has a tube
diameter greater than 90 mm, you will have to buy the Baader

bracket
kit.

If all you need is a portable mount for visual use, consider

buying
a


Celestron Nexstar 80GT for $200. You can sell the OTA on eBay for
$80-$100, and you'll have a decent goto mount for the Tak. I did

this


with a TV85 and it works well.

"But existing is basically all I do!" - Phillip J. Fry



how long does it take to set up?



this is very intriguing, but how long do the other (non goto) mounts
take to set up?




An alt az mount with no electronics and a tak sky 90 takes at most ten
seconds to set up. For something that light you could leave it
assembled and take it out in one piece.
