There are a variety of options (as I am sure you will see) but if
Parallax rings are the preferred method, you would need the
DOVELM2:

DAP5:

and Parallax rings (drilled for a DAP):

I would recommend going with the Tak plate:

and the Tak rings:

Due to the increased rigidity.

Thanks Herb,

Can you and others go through the setup starting at the top of the
mount. For instance does the Tak dovetail plate attach directly to
the top of the mount or does it use a saddle plate? What about AP
plates? Parralax rings are less expensive than the Tak tube

rings.

Do they work fine? If people want to email me directly that would

be

great as well.

Thanks

Jeff

The 900 handles that fine.

Subject: [ap-gto] Follow Up on Attaching TOA 150 to AP900


Hello,
I own an new AP900 and am looking to add a TOA 150. Previous

post

were

talking about how to attach these two components and I was

hoping

someone might offer some follow-up on how the system is

working.

I do

almost exclusively imaging so I really want a stable system. I

would

need to have a TV 102 guidescope on top. Am I pushing the mount

to far?
