  1. This is a decent 10mm to 22mm zoom. But not so good at the higher magnifications between 10mm and the 7.5mm maximum Zoom. I checked it out this morning on the moon in semi daylight, and compared it with 12mm / 10mm / 9mm Plossls on the 700/76 3"beginners scope - then on the 200p dob. You need to back the zoom off to gain focus, only using the bottom two thirds of the Zoom available. The story is the same if you use a Barlow. I used a 1.5x magnifier = bottom one third of the zoom was available = 10mm equivalent And a 2x Barlow = no zoom is available = 10mm equivalent It matches the Plossls for moon detail up to it's maximum limit of magnification. So it will make a very nice 22mm / 10mm dual role eyepiece. But it is never going to work at the 7.5mm quoted in the specification. And when you swap onto the next eyepiece - the target has moved due to a slack fit and misalignment in the focus tube. (maybe I got a bad-un) Advantages: Price / wide views / one size fits all / good construction - with black coated metal threads for the filter (not cheap painted threads) Disadvantages; You need to use the rubber eye cup for internal reflections / usable range = 10mm equivalent / there is misalignment when swapping onto the next eyepiece. So in summary - just keep the 25mm / 10mm EP's which come with the Skywatcher gear. Then get yourself a Barlow, or buy a decent Plossl like the 6mm Revelation to achieve your higher magnifications.
