1.25" fit low-profile nose-piece with filter thread to fit Philips ToUcam Pro 840K webcam (and other "thin case" webcams).
The Astro Engineering webcam nosepieces are the original and still the best - they have many imitators but no other webcam nosepiece has the anti-reflection baffling used on all the AE models.
Simply unscrew the lens on the camera and screw in the nose-piece - and you're ready to start high resolution imaging.
Unique computer designed baffle system The AC624 nose-piece is precision turned from black Delrin and features a filter thread and a computer designed stepped baffle system to minimise reflections and improve contrast - the low-profile shape has been specifically designed to help imaging with telescopes with limited inward focusor movement. The design features a short nose-pieces extension and no rear flange - to allow the AC624 to fit as deeply as possible in to the eyepiece holder. And actually allow the body of the webcam to rest directly on the outermost edge of the eyepiece holder.
The AC624 is particularly useful for imaging with telescopes like some models of the Coronado PST (Personal Solar Telescope)- see lower picture.
We recommend the AC582 IR and UV blocking filter for use with this nosepiece (see botton left).
