The Explore Scientific ES HR Coma Corrector is one of the highest quality units available on the market today. Its four element design yields a superbly corrected field with coma correction right to the edge of the field.
The HD flattener kit for the Vixen FL55SS consists of a field flattener lens and a connecting tube ring, which is designed for the FL55SS optical tube.
The Explore Scientific 3in 0.7x Reducer - Corrector reduces the effective focal length of a particular instrument by the factor 0.7x (for f/8) and 0.8x (for f/10) respectively. The reducer/corrector not only reduces the focal length but also operates as a very effective field flattener.
The Takahashi TOA-35 Flattener corrects the field on TOA and TSA telescopes for visual use. The image circle produced by the flattener is 40 mm, with star images of 2 microns in the center and 8 microns at the edge of the field.
The William Optics 0.8x Reducer / Flattener is compatible with the Z126, GT153, GT102, GLT156 & FLT132 to provide a sharp flat field ideal for widefield imaging.
This revolutionary new WO FF68II Adjustable Flattener was made for 6 -7.5 F ratio refractors. This high-quality flattener has been engineered and CNC machined for usage with our FLT 132, 102GTS and other APO refractors.
The reducer HD kit for the Vixen FL55SS consists of a field flattener lens, a focal reducer and a connecting tube ring, which is designed for the FL55SS optical tube.
