365Astronomy Imaging Flip Mirror for Astrophotography and Precise Focusing

الوصف

Designed for convenient CCD imaging with telescopes. The device has a 1.25" nosepiece, threaded for standard filters on 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. 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 adapter to accept cameras with 1.25" nosepieces is available separately (prod.code 365596) Please note: Your focuser will require 80mm of additional inward focusing distance from the normal focusing position to compensate for the length of the unit. On the second image there 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 we could achieve parfocality. The eyepiece holder (that is part of the Imaging Flip Mirror) is also adjustable, so with these two adjustable 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.
