The good first, but there isn’t much to list. This system will give good images of the moon and during daytime for nature watch. For the rest such as astronomical use it should be avoided. The stand is of very poor design. The smallest touch sends the tube into vibrations. It is almost impossible to focus since the moment one touches the focus wheel it starts to vibrate and you can never see whether the focus is working. The inccluded eyepieces are unusable. Used two of my own plossl, a 25 and a 10mm. The 25 is the only one that works giving a magnification of 36x, anything more than that will not focus simply because of the horrible wobbling of the whole thing. Attemting to change the eyepiece results in the found celestial object dissapearing. The flexible movement rods work only partially with jerky movements. I would strongly reccomend researching other models with a decent stand. I cannot comment on the actual optics since the totally inadequate stand prevents a serious assesment of the refractor itself.
