Omegon 1.25″ Variable Projection Adapter
Want to start photographing the Moon, planets or nebulae - but without investing in complicated equipment? The Omegon 1.25″ variable projection adapter is an affordable and elegant solution that opens the door to astrophotography. It combines a projection adapter and a focal adapter in one compact aluminium body, adapting to both your telescope and your photographic goals.
Two shooting modes in one adapter
The adapter works in two modes, giving you real flexibility in the field.
Projection mode
Insert a standard 1.25″ eyepiece into the adapter - Plössl or Kellner eyepieces up to 38 mm in diameter work well here. This mode delivers significant magnification, making it ideal for detailed shots of lunar craters or planetary surface features.
Focal mode
Remove the eyepiece and use your telescope's own focal length directly. This mode suits wide-field shots of the full Moon, large nebulae or galaxies.
Variable focal length - no eyepiece swapping needed
The adapter offers a continuous zoom range from 90 to 125 mm - simply slide the rear section of the adapter body to adjust the focal length smoothly. You do not need to swap eyepieces. This is a real advantage when observing conditions or your composition changes quickly and you need to react without delay.
Universal compatibility
The adapter fits the standard 1.25″ focuser opening found on most refractors, reflectors and catadioptric telescopes. On the camera side, it uses the proven T2 thread. Simply add a T2 ring to match your camera's mount - Canon EF, Nikon F, Sony E and others are all supported - and you are ready to shoot.
Solid aluminium construction
The entire body is made from aluminium. It is lightweight, durable and comfortable to handle even on cold nights.
Who is this adapter for?
The Omegon 1.25″ adapter is a great choice for beginners looking for an accessible way to start photographing the night sky without buying expensive dedicated cameras. More experienced users will also appreciate the variable focal length and solid build quality. If you own a DSLR or mirrorless camera with a T2 ring and a telescope with a 1.25″ focuser opening, you have everything you need to take your first successful astrophotographs.
