The
Vixen VMC200L Telescope Optical Tube with 7x50 Finderscope and Accessories 2633OTA / 2633 is a unique
catadioptric telescope. It incorporates a primary

mirror and a
meniscus corrector just before a secondary mirror. By doing so, light is corrected twice in the
telescope tube.
The end result is that
spherical aberration and
field curvature are corrected to a high degree of optical performance. The
VMC200L 2633OTA 's by
Vixen primary mirror is f/2.5; the compound optical system is f/9.75. This makes the system much more compact
telescope and portable than its competition.
This
Vixen Telescope has the optical correction placed before the secondary mirror, the
Vixen VMC 200 L 200mm avoids the necessity of having a corrector plate and all the dewing problems associated with a closed
optical tube.
An additional key feature is the
rack and pinion focusing that is placed behind the primary mirror, the focuser accepts 2"
telescope eyepieces and accessories with an optional adapter. . The use of this
telescope focusing system eliminates the image shift associated with most other
SCT telescope systems. This is especially important when using high power magnification or
astro-photography. When focusing, the image is stable and easy to adjust. Dont have a
telescope mount? The
Vmc200L telescope also comes with
Vixen VMC200L Telescope with Vixen Sphinx Mount 2733,
Vixen VMC200L Telescope with Vixen GP2 Mount and
Vixen VMC200L Telescope with Vixen GPD2 Mount.
