This is a veryuseful upgrade to the Skyguuder Pro. I have the SGP with ipolar and had been immediately frustrated with the original wedge when the circle of alignment jumped around when trying to match the cross on the ipolar screen. This product makes it a much more controlled process. It is also a rather more solid item. So Iím very happy with it. Iíve knocked a star off for two reasons. First at least in UK it comes bundled with an extender for the weight rod. Iíd rather buy a slightly larger weight that I can use nearer the axis to get a lower moment of inertia for a given balancing moment, and lower the risk of knocking a longer rod. Paying for the extender to get the wedge is annoying. Second the product is rather confusingly divided into a low latitude and high latitude version. They are the same ! It is just a matter of the shipping configuration which can be changed. If you live in the UK you may as well order the high version as I did. But both those gripes are irrelevant to the operation of the product, which is a worthwhile upgrade.

I have not yet had chance to use this item in the field due to cloudy skies but me impressions of it are excellent. The mount is engineered to the highest standards and is absolutely stable on my tripod. Adjustments are positive and accurate. It represents a quantum leap in stability over the conventional Sky Watcher Star Adventurer mount and I am so looking forward to using the mount on the next clear night. I would recommend this item to anyone who expects the highest standards of performance from their equipment.
