Celestron Zoom Eyepiece 7-21mm, brand new and unused. (I have looked through it once with a Vixen R130Sf for inspection) These are imported from overseas, so I am offering them at a low price. Beginners and children, in particular, often struggle with the following aspects of astronomical observation, so please consider this as a solution. Even if you can introduce objects at low magnifications of around 20mm, if you are not used to it, you will lose sight of the target when switching to a high-magnification lens, and you will not be able to see it at high magnification no matter how long you wait, which often leads to a loss of interest in astronomical observation. In such cases, this zoom allows you to zoom to the equivalent of a default high-magnification lens without switching lenses while continuing to observe the target. This is a story from my own experience long ago; after all, astronomical observation is all about seeing. I am offering a zoom eyepiece that has a slightly higher magnification (over 14% increase) than the common Celestron Zoom Eyepiece 8-24mm. This is because I have adjusted it to the high-magnification side, and the 8-24mm costs about 10,000 yen, so the aim is to provide a lineup that is more affordable. Also, with a focal length slightly shorter than 70mm, you might want a little more magnification. This is for those people and those who wanted a higher magnification. For example, the Vixen Porta2 A80Mf has a relatively long focal length of 910mm. Even at 7mm, it becomes 130x magnification, and from 20mm at 46x magnification, children, in particular, will surely miss the target if they are not used to it. With the zoom, however, it is easy to introduce at 21mm, and by zooming while looking, even children can introduce it to the maximum magnification in one go. The last photo is of Saturn taken on 2023/9/9 with an A80Mf and this same zoom that I own. The sparkling eyes of the child who found Saturn's rings for the first time on their own are something that even a parent can be moved by. Telescope Vixen Vixen Constellation Eyepiece
