365Astronomy Imaging Flip Mirror for Astrophotography and Precise Focusing 

Designed for convenient CCD imaging. The device has a 1.25" nosepiece, threaded for standard filters at one end, which is inserted into a telescope's focuser, and an M42x0.75 T-mount thread on the other end to connect a suitable CCD camera. A 1.25" helical focusing eyepiece tube is provided for visual observations. (If you unscrew the 1.25" nosepiece from the telescope side, there is also a M42x0.75 thread - T-thread)

In visual mode, the internal lever-operated mirror is angled at 45 degrees to channel the light path to the eyepiece in order to easily focus and frame the image.

In imaging mode, the mirror is taken out of the light path to direct the light path to the camera.

An adaptor to accept cameras with 1.25" nosepieces is available separately (prod.code 365596)

Please note: Your focuser will require appr. 74 - 78mm of additional inward focusing distance from the normal focusing position to compensate for the length of the unit. Whether 74 or 78mm, it would depend on how you'd use the reverse T-adapter. if you use it with the locking ring, the back focus would be 78mm, if you use it without the locking ring, it can be reduced to 74mm. The overall length of the enclosure is 72mm.

Below is an example of a planetary imaging setup with a Imaging Flip Mirror, ZWO Filter Wheel and ZWO ASI120MM monochrome camera. With the help of a Variable Locking T2 Extension (there are two slightly different versions, one from Lacerta and another one from TS Optics) we could achieve parfocality.  The eyepiece holder (that is part of the Imaging Flip Mirror) is also adjustable, so with these two adjastable items we can achieve various positions of the eyepiece thus parfocality can be achieved with eyepieces of various focal lengths. To see approximately the same field, you'd have to use an eyepiece with approximately 6mm focal length. Please note that this setup might not work for a Newtonian telescope due to the long back focus requirement.
