This lens adaptor is designed to fit for CMOS or CCD cameras that has a C-mount thread. The adaptor provides 0.5X focus reduction which will increase the imaging area by a factor of 4. This adaptor is suitable for 1.25" focusers or visual backs.
Fits iOptron iE5100 (#5250) Planetarium Imager and other similar cameras that with a 1/2~1/3" imaging sensor..
Features
Fit a camera with 1/2 ~1/3" sensor
Fully coated optics
Telescope Adaptation - 1.25" barrel, threaded for 1.25" filters
Camera Adaptation - C Mount Male Thread (UNC 1"-32)
Antlia ALP-T Dual Narrowband Ha & OIII 5nm High Speed Filter - 2" Mounted
ALP-T Dual Band 5nm Highspeed Filters are further optimized to work with high-speed imaging systems by shifting slightly the passband and center wavelength. Using these highspeed filters between optics f/2.2 and f/3.6 shows much stronger and more contrasted in nebulae imaging compared to the standard version.
