I read this wonderful thread and realized that I need a ZEISS DIASCOPE 20-75x zoom, 25.1mm to 6.9mm:
Upon checking, however, this dreaming eyepiece has long gone. I cannot find it anywhere. Meanwhile, I found ZEISS Victory Vario Eyepiece is readily available; focal length range unknown:
My question is how similar they are in terms of optics and specs. Is ZEISS Victory Vario Eyepiece is good replacement for ZEISS DIASCOPE 20-75x zoom?
Update: and what adapter/accessories I will need to fit ZEISS Victory Vario Eyepiece to a 1.25" diagonal if I purchase one?
