thanks Mike, one more question how could I paralled a polar scope axis (which is off-axis) to RA axis, is that same process to a finderscope? thank you.
I would assume that as you rotate the RA axis a distant object (I think Polaris would work really well for this) should stay centered in your polar scope. This is how reticles are positioned in polarscopes built into the RA axis.

Point your mount at a distant object - like a clearly identifiable point on a distant radio tower, hill whatever. If you can't do this from your location during the day, align your mount roughly north at night. Look through your polarscope and center Polaris. Lock the DEC axis and rotate the RA axis. If Polaris stays centered in your polarscope, you are done. If not use those set screws on the polarscope holder and center it again - rotate and repeat till Polaris stays put.

If you can arrange for the RA axis to be made horizontal, then do so and place a level on the housing (assuming it is flat and parallel to the axis) and make it as level as you can. Then do the same with the the polarscope. This will make the two axes parallel in one orientation. You will have to do this in one more orientation preferably perpendicular to the first one. I don't have a good sense of the mount or the polarscope attachment. So this is the best I can offer at the moment.
