Takahashi Mewlon 250 Corrector

Takahashi Mewlon 250 Corrector MCR250

  • Takahashi Mewlon 250 Corrector is a three element ED corrector that eliminates coma and flattens the field.
  • Takahashi Mewlon 250 is part of the baffle tube assembly which is switched out by the user.
  • Takahashi Mewlon 250 Corrector goes well with wide field oculars and medium format CCD cameras.

Introducing three element ED correctors for the Mewlon-250 and 300, these proprietary correctors eliminate coma and flatten the field while also reducing the f-ratio slightly for each. Both the 250 and 300 Mewlon CR Correctors were designed to be a visual and imaging corrector. The corrector is part of the baffle tube assembly which is switched out by the user. A 1.5x and 0.73x reducer are also being introduced to compliment the usefulness of the Mewlon CR Corrector. The Mewlon can be viewed as a tri-focal device with the corrected fields at three different focal ratios.

Designed to work with every Mewlon-250 and Mewlon-300 ever made, the Mewlon CR design makes use of about 20 years of production. Performing excellence with the Mewlon CR Corrector would be the use of wide field oculars and medium format CCD cameras.

Celestron Reducer Lens .7x - EdgeHD™ 1100

Celestron’s new EdgeHD reducers feature a custom 5 element optical design engineered to maintain the flat-field performance of our award winning EdgeHD optical system. Unlike generic reducers, our premium reducers provide substantial back focus to accommodate an assortment of imaging accessories. EdgeHD reducers offer high index optical elements, including extra low dispersion, exotic Lanthanum elements, which provide high contrast viewing while minimizing chromatic aberration. All air to glass lens surfaces feature multiple layers of coating for maximum light transmission and color correction and contain blacken edges to minimize internal reflection and maximize image contrast. Large diameter lens elements, up to 60 mm clear aperture, ensure that the optimized image circle remains at a generous 42 mm for use with large CCD sensors. Incorporating computer assisted CNC machined aluminum housing, for precise spacing and alignment of optical elements, and threaded metal covers on the lens assembly to protect your investment from dust and scratches, our reducers offer you an outstanding mechanical design. With the fastar option on all EdgeHD optical systems, coupled with the .7x reducer, your telescope becomes the most complete imaging system available in its price range today.
