Primaluce Lab Deluxe 2.5" Field Flattener for AIRY BLACK APO Refractor Telescopes
The "Deluxe 2.5" field flattener for AIRY BLACK" is specially designed for our AIRY BLACK apochromatic refractors, but it is also compatible with may APO telescopes, like the Sharpstar CF90.
It generates a very large flat field, to use with cameras with big sensors, up to Full Frame (24x36mm). In this way, the pictures will be perfect, with pinpoint stars up to the edge of the field!
This flattener is directly screwed to the thread back on the focuser's tube of the AIRY BLACK telescope: in this way you avoid the unwanted flexures! On the camera side, it has a M48 thread for connection to DSLRs (it requires M48 ring) or cooled CCD cameras.
Nikon DSLR connected (with Nikon M48 ring) to the Primaluce Lab 2.5" field flattener: everything is then threaded to the AIRY BLACK 90T focuser. Image is for demonstration purposes only. Telescope and camera are not included.
