Lunt 0.8x Reducer/Field Flattener for 80MT, 100MT, and 130MT Telescopes. This reducer/field flattener is designed for f/7 telescopes between 80 mm and 130 mm. Designed for nighttime imaging, the 0.8x reducer/field flattener features a 2-inch nose tube and multiple thread types, making it compatible with most cameras, focuser types, and T-thread adapters.The left image shows a typical setup of the field flattener with f/6 to f/7.5 refractors and a digital SLR camera.-- The flattener is on the far left. It disappears completely inside the focuser.-- Next to the flattener is an M48 extension tube to get the proper distance. The extension tube is available in several different lengths.The Megrez 90 is an f6.9 APO doublet using an FLP53 glass element. The Megrez 110 is an f5.9 APO doublet using an FLP51 glass element. The slightly longer focal length and the FLP53 glass would seem to give the 90 a slight edge in color correction for visual use. A call to William Optics (by the enabler) confirmed that the 110 was really ... Add Equipment To The Astronomy.tools Database. Help us to grow by adding additional equipment to the database.

Stable and precise 2" RAP focuser holds heavy photographic accessories safe, 360° rotation. The 1:10 micro-reduction is ideal for astrophotography and allows precise focusing.The PrimaLuceLab 2" Field Flattener for AIRY BLACK is designed to produce a very large flat field and is best used with cameras with large sensors up to APS-C. This ensures pinpoint stars even at the edge of the field! The flattener directly screws on to the thread back of the focuser's tube to avoid unwanted flexures.Inside the tube, behind the lens there are a series of rings, or baffles, that increase in thickness towards the focuser. These add stability to the tube, but their primary role is to reduce the amount of stray or unwanted light inside the tube that can reduce contrast at the eyepiece or camera.
