There are other types some that clamp to top of eyepiece but I find they dont grip enough. This type also available in other brands works fine.
Note you need a 40mm or 32mm eyepiece giving good exit pupil and eye relief. Can work with shorter focal length eyepieces but I tend to use lower power and zoom in with the phone.
This type of astrophotography is called digiscoping (also known as afocal projection). Best for the Moon since it requires short exposures.
