Looking for Alt-Az tracking mount
Posted 16 March 2011 - 02:56 PM
I do not really want the added complexity of a goto mount. I have several but I want something simple here. I don't really want DSC's either. I want to visually locate an object, lock down the scope and let it track (at least for a while) without having to constantly nudge the scope. I would like positive locks so that overeager viewers won't move the scope off target and slow motion controls would be a real plus.
I have tried various EQ mounts and dislike the extended setup times required for accurate alignment.
I would like to keep the cost of the mount plus tripod under $1000.

I thought that for an alt-az mount to track, it has to be goto.

I checked the Orion website and downloaded the manual. It sounds pretty good but it won't track objects above 60 degrees (above the horizon). Even if it could I don't think a long refractor would work without the tube hitting the mount. But we are definitely on the right track.

I have a couple of them so if you have any questions let me know.

The NexStar SE mounts to indeed track, but the thing to bear in mind with mounting refractors to this mount is the OTA length and balance point.
You'll then need to be sure you understand and set the slewing limits so that your OTA won't slam into the mount base when slewing to targets close to or at Zenith.
Another option would be to use something like the APT Astro Wedge in order to mitigate against this.

How about the Orion teletrack?
The OP wants this mount for an f6, 100mm scope focal length of 600mm).
The Teletrack (in addition to its 60 degree limit) is only intended for optical tubes up to 15" long and weighing 8.8 lbs or less. This limits its use to very short tube refractors or small Cassegrain type scopes (90mm Maks, etc).
It's a pretty limited use mount.

I will have to give them a call for more details. On the Portamount or Voyager it could do the trick. I will let you know if this works out.

I also went to JMI and ordered the Train-n-Track unit. I am not exactly convinced this will work as I want it but it seems pretty close.
The testing begins next week.

I am wondering if this would be an improvement over a Celestron SE6/SE8 mount?
