What Adapter Do I Need for My Star Adventurer That Will Allow Scope to Point Southward?

I use a Sky-Watcher Star Adventurer with an AT60ED telescope. Since I added a ZWO EAF, the collision of the EAF bracket and declination knob disables the ability to rotate the telescope toward southern targets. In the following images, you can see that the golden pin prevents the bracket from rotating further.

The following two photos show the connections between the Star Adventurer and the AT60ED.

As of now, I simply thread the AT60ED's shoe onto the Star Adventurer. What I am hoping to do is use an adapter to raise the AT60ED higher above the Star Adventurer's mount so that the AT60ED can be rotated without hitting the rotation knob on the Star Adventurer. However, I don't know what I need.

 

Can you provide me with a possible solution?

 

Thank you!

I suppose you could try a tripod leveling base or panoramic base between the dec bracket and the dovetail to get a bit more space. They're both basically disks with 1/4" 20 threads and either level or spin, which you don't care about. Not sure if it'd be enough height; you'd want to measure first. That would also make balance harder and increase the moment arm, making the load harder for the mount, and it looks like you're already pretty close to the limits of the star adventurer.

The problem with this setup is that anything you add to increase the height will increase moment arm and introduce balance issues, as @whodidyouthink said.  Having said that, my personal suggestion would be a small quick release adapater which will still keep lots of tension on the new mount interface you're creating, and can add as little or as much clearance as you'd like, assuming that you can find one that's the height you're interested in.

 

Here's one such example:  https://smile.amazon...28168165&sr=8-5

Rotate the AT60 in its ring so the focuser faces "up" (away from the bottom of the mounting shoe).

I may not be getting this, but once it's mounted, the OTA won't rotate because of the connection between the EAF bracket and the ring mount.  I don't own one though, so maybe I'm mistaken.

Yes, you're correct.  So rotate it *before* mounting it.  Leave the focuser on top.

You can also turn the "foot" around (remove the scope ring, turn it 180-degrees, put it back on) so the foot doesn't interfere with the EAF.

Or do both!

Ah, simply removing the ring mount, turning it 180 degrees, and then replacing it allowed me to turn the mount without interference. Thanks for the suggestions! A simple solution to a simple problem that I completely overlooked. crazy.gif
