Astrozap is pleased to announce something new to the astronomy community. Astro Caps!
It’s not just another round hole focusing cap; it’s a multifunctional wheel system with the following features:
Integrated wheel system which allows for quick “shutter” like operation. Simply turn the thumbscrew to open, and turn to close. No plastic plugs required!
Each AstroCap is shipped with one triangle wheel for quick focus. Triangles create diffraction spikes, which makes it easier to focus.
No more trying to focus three blobs from using a round hole focusing cap. Triangles are the answer!
Optional wheels for checking collimation & off axis viewing are available.
AstroCaps are made to fit both your telescope & AstroZap aluminum dew shield.
Caps are made from aluminum and powder coated to match your scope and or dew shield.
Wheels are made from ABS plastic and are designed for quick changeovers. No tools needed!
