Using the ioptron Dec Adapter was a pain as it had too much play to be really accurate, this part fits like a glove with no play meaning easier to adjust to gain the target.
Worth the upgrade.

Simply brillliant. I use a very heavy (and frankly expensive) lens mounted to the Ioptron dec adapter and the moment i loosen the knobs i have no confidence it will stay put! i also dont have great confidence that once retightened it is positioned 'flush' so there could be play in the adapter as the mount rotates. The WO version is a little less user friendly in the sense that i usually prefer leaving the adapter on the lens mount which means having a mini flat head screw driver to hand to loosen and tighten the 'grab nubs' that fixes the adapter to the IOptron but it is worth this slight extra faff. Once on, its only a single turn know needed to loosen/tighten the adapter to rotate it and it does so perfectly flush so its a smooth controlled movement. Makes minor adjustments on my 600mm lens alot easier and i have more confidence it is grabbing tightly. Its a no brainer this one. Dont tolerate the standard adapter, spent a small amount of money on this, you wont be disappointed.

The dec adapter on the skyguider pro is sub-optimal to say the least so I went for the upgrade using this adapter and the matching saddle plate. It’s a very snug fit and there are grub screws in 6 positions to make the fit perfect. That leaves you with a single bolt to clamp it tight. No discernible movement of the scope when tightened up which was a major issue with the ioptron stock adaptor. The saddle plate clamp is equally impressive and it’s transformed my experience with the mount.
