PrimaluceLab Deluxe 2.5″ Field Flattener for AIRY BLACK
The PrimaluceLab Deluxe 2.5″ Field Flattener is specially designed for our AIRY BLACK apochromatic refractors and it generates a very large flat field, to use with cameras with big sensors, up to FullFrame (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 telescope: in this way you avoid the unwanted flexures! In the camera side, it has a M48 thread for connection to DSLRs (it requires M48 ring) or cooled CCD cameras. In order to obtain the best performances, you have to set sensor position at 55mm back focus distance from rear field flattener thread (for a DSLR camera, you simply connect the DSLR camera body to the field flattener using the M48 adapter).
