Nice addon mount, makes any alt/az into eq
But beware the following
The bolt holding the supplied dovetail onto the az goto needs to be changed to something shotrer, maybe even grub screw as it will foul the goto while tracking
When using the goto do not set the inclination to your local value, it needs to be 90-your local value, you will not be able to polar align without doing this (mine needs to be set to 37 on the scale to align properly)
Once the alignment is complete tighten everything and remove the 2 az bolts, these can also foul the tracking

Dont be suprised when you try and goto if the whole lot spins round, even tho you are only moving sideways a bit, this is to allow full tracking (if you have ever used a manual eq mount before you will understand being a contortionust is a goid thing )

All in all a good product
Dont forget to buy the counterbalance weight and bar

It's good quality for little money
