So I am trying to figure out how to mount a ZWO guide camera/scope setup with a camera lens/zwo 1600 setup on this mount. I dont want to use a dovetail type where guide camera on one side and lens /camera on other side. Hoping there is some kind of mount situation for the lens or zwo 1600 which I can attach the guide scope. OAG is not an option either. Any thoughts? I can only come up with duct tape

Well my plan is to mount it on the other side of the of the dovetail across from the laser pointer. My ZWO mini scope will be here in a couple days.

Depends on your  lens.  This lens (150-600mm) has one of those single foot mounts (removable).  I found the mating of the foot mount ring that attaches to the lens had a really small amount of slop even when tightened to the max (actually, upon reflection, it may have been the lens draw tube that had some free play when it was extended outwards).  I saw someone did this with their lens (different) so I decided to try with my lens.  This is the only lens I can do this with, none of my others have the 'free space' to do this.

 

Mine requires dissimilar ring sizes (one is 1/2" smaller) hence the funky 1/4"  spacers top and bottom.  Scopestuff will sell you an unmatched (if necessary for your lens) set for 2x cost of the more expensive ring if your lens has the available space to do this.

Ideally, the forward ring should be mounted all the way back towards the rear, but as is I am able to use the standard mounting positions on the dovetail, all it does it limit my low FL to 300mm (the lens tube can't retract all the way in)

You can reverse the counterweight bar and camera mount on the DEC bracket and it will give you a longer moment arm.

I did this too. Works much better.

I am planning on getting similar set up with Skywatcher . One basic question though,  does the guide cam need to point the same direction as the main camera or just any bright star?

I am confused, I thought the SkyGuider pro couldn't act as a GoTo mount. Is the guide scope / cam only used to help frame the shots  and so manual movement of the camera is still necessary right?

The guidescope needs to point at approximately the same location as the imaging scope/lens, otherwise field rotation will occur with the guiding.

The Skyguider Pro is not a goto mount, as you note; only the RA axis is driven. The autoguider is used to improve the quality of long-duration exposures by tracking in RA more accurately than the mount's RA motor alone can provide. The guider also allows you to dither (in RA only), which helps reduce noise in stacked images.

Thank you Poochpa, that was very helpful and informative.
