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

mount,
plug in the battery pack and hand control, enter the location, date

and
time, and do a two star alignment. One thing I forgot to mention 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
Planetarium:

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.

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?
