TPO Camera Adapter - 1.25"

Want to take pictures of the moon and planets through your telescope? Our Camera Adapter is the simplest way to get started. It attaches to your telescope by sliding into either the focuser or eyepiece holder, and then your SLR camera attaches to the other end of the adapter via a T-Mount (sold separately) made specifically for your camera brand (Nikon, Canon, etc.). An eyepiece can be inserted into the barrel of the adapter and locked down snuggly by turning the thumbscrew, and the magnified image of the object is projected onto the camera film plane. This is called "eyepiece projection" photography, and it is lots of fun.

The picture above shows how you can unscrew the camera adapter for prime focus photography. The small piece can accept a T-ring on the larger end, and then slide directly into your telescope's focuser or eyepiece holder on the other. This set up is nice for the moon. You can also leave the camera adapter in one piece (click on the "Images" tab to see how that looks) for a bit more magnification (without the eyepiece), or finally, as I mentioned before, slide in a Plossl or Orthoscopic (to name a few) eyepiece for high power images of the planets, moon, etc.

Please note that not all 1.25" eyepieces will fit inside the barrel of the camera adapter. Some almost fit, and removal of the rubber eyeguard and/or rubber grip (in instances where the eyepiece design allows for removal) is all that is needed for success.

Finally, remember to buy a nice cable release for your camera if you don't have one...the more magnification, the more small vibrations and movements will affect the photo.
