Is that Svbony altaz mount adequate for the 102ED?
I don't know what you expect from an alt-az mount, so it's hard for me to answer that. For visual use for me, it's every bit as solid as it needs to be--I have no trouble using it even with high-power eyepieces, though with high-power eyepieces, you'll be nudging those slow motions pretty often. It's easily as solid as the old Mizar AR-1 mount. It's not as solid as the EXOS2-GT PMC-Eight I just bought for AP use, but that's in the HEQ5 class.
I did modify it to install a dovetail clamp that uses two wedged clamps with two screws, rather than using the screw-point itself as a clamp. That took about five minutes. And I moved the arm to tilt over so that my OTA could point straight up.
Now, the old Bogen tripod, which I've owned since 1977, has definitely seen better days. It's not at all as solid as it used to be, but it was in the surplus pile. As a large-format photographer, I have a number of hefty tripods.
