Meade f/6.3 CCD Focal Reducer/Field Flattener Series 4000
Made in Japan - Free USA Shipping
The Meade 07049 f/6.3 Focal Reducer & Field Flattener is a
4-element multicoated 41mm lens in a metal cell which threads upon the
2.00"-18 rear cell thread of any 8.0-16.0" Meade Schmidt-Cassegrain or
Ritchey-Chrétien telescope. It also is compatible with Meade's lineup
of APO refractors and 7.0" Maksutov-Cassegrains(though not ideal for either, because they don't benefit from the field-flattening influence).
The Meade f/6.3 Focal Reducer & Field Flattener reduces the
telescope's effective focal ratio by a factor of 0.63. Thus an f/10.0
Schmidt-Cassegrain becomes an f/6.3, an older f/6.3 becomes a f/4.0 and
an f/8.0 Ritchey-Chrétien becomes an f/5.0 system. With these drastic
changes upon the telescope aperture, your exposure times will
significantly shorten, making astrophotography easier.
of the f/6.3 Focal Reducer & Field Flattener also improves the
edge-of-field resolution of the telescope by flattening its field.
2.00"-18 Female Threads On One End, 2.00"-18 Male Upon the Other
Duplicates telescope's rear cell thread, allowing attachment of standard rear cell accessories
Rubber grip ring allows easy installation when wearing gloves
Ideal for reduction of magnification with terrestrial viewing or for shortening exposure times in astrophotography
