The Aurora Flatfield Panel is a new light source technology for taking flat field images for use in calibration with digital images.
Gerd Neumann's Ronchi Eyepiece employs a chrome-on-glass grating of 5 lines per millimetre, providing a high-contrast display of starlight that enables good analysis of the optical train.
Using this filter, you may use much longer exposure times to capture faint moons, rings or ring fragments as they do reflect sunlight and have no absorption band.
Camera Tilt Unit will solve most problems associated with tilted focal planes that result from subtle miss alignments between camera and scope.
The Photographic Ronchi has the same high-quality grating inside
Gerd Neumann's Ronchi Eyepiece employs a chrome-on-glass grating of 10 lines per millimetre, providing a high-contrast display of starlight that enables good analysis of the optical train.
