Vixen Optics 39957 overview

  • 1Description

Vixen Optics put their VMC95L 95mm f/11.1 Maksutov-Cassegrain Telescope together with the manual Porta II alt-az mount to give you a complete observational kit that is ideal for astrophotography or imagining near-space objects like the Moon and planets, or for terrestrial digiscoping. Similar to their Schmidt cousins, this Maksutov variation exchanges the front corrector plate with a convex meniscus lens which not only eliminates the need for periodic collimation, but the nature of the lens requires a smaller secondary mirror which limits obstruction and increases contrast. The Mak-Cass optical path results in a slower focal ratio and narrower field of view versus a similar Schmidt-Cass, but the optical benefits makes this an ideal scope for planetary and double-star observation with a resolution of 1.22 arc sec. Dual eyepiece holders and an internal 90° flip mirror make this OTA an easy choice for imaging as it allows a camera to be installed in one holder while an eyepiece in the other allows you to check the focus and position without having to remove your imaging system.

Complementing the scope is the Porta II alt-az mount. This innovative mount uses a friction control system that allows you to simply turn and aim the scope with your hand for fast adjustments and when you release it, it stays in place. For fine-tuning and tracking, there are two slow motion cables to make minute adjustments and to reduce vibrations. With a 15 lb payload capacity the mount can easily handle the VMC95L, and the included dovetail plate gives you the ability to mount other OTAs for astronomical viewing. An adjustable-height aluminum tripod rounds out this rig to give you a solid platform for making your astronomical and terrestrial observations.

  • VMC95L 95mm f/11 Maksutov-Cassegrain Telescope (OTA Only)

    Lightweight, portable, and powerful, the Vixen Optics VMC95L 95mm f/11 Maksutov-Cassegrain Telescope is an ideal choice for observation or imaging. It features an internal flip-mirror mechanism that allows the light path to be directed toward one of two points: 90° upward or straight through. This configuration supports the use of two eyepieces for quickly changing magnification without having to switch eyepieces, or of an eyepiece at the 90° position and an imaging system straight through. For imaging, simply flip the mirror up to check alignment and tracking accuracy between exposures and flip it back down to use the camera. The straight-through port has threads that accept most imaging and camera mounting rings for eyepiece projection, prime-focus, and afocal imaging techniques.

    Optically, the Maksutov design exchanges the conventional front corrector plate of a Schmidt with a convex meniscus lens, resulting in a smaller secondary mirror that limits obstruction and increases contrast while eliminating the need for periodic collimation. The Maksutov optical path results in a narrower field of view versus a similar Schmidt, but the optical benefits, when coupled with the VMC95L's larger aperture and multi-coated optics, make this an ideal scope for solar, lunar, and planetary observations, while being able to resolve bright deep-sky objects like stars, clusters, galaxies, and nebulae.

    This version of the VMC95L is offered here without a mount or tripod, for users who have a reliable support system, but a Vixen-style dovetail plate is included to accommodate a variety of mounts. For observations, a 25mm eyepiece is included, as is a red-dot finderscope and bracket.

    • Mounting bracket included
  • Porta II Alt-Azimuth Mount

    Built to support a 20 lb payload, and equipped with two fine adjustment handles for whole circle slow motion in both directions, the Porta II Mount from Vixen comes with a sturdy set of legs that adjust from 35 to 51". The Porta II minimizes support-system-oriented frustration when searching for and tracking celestial objects.

    The Porta II is solid, and its slow-motion flexible handles minimize vibrations to keep the view sharp. Precision tracking of planets and ships on the horizon becomes a simple event thanks to a fine-tooth geared drive that's activated by turning the elevation or azimuth control handles.

    The "World-Standard" dovetail system ensures that the Porta II can be used to support most dovetail-mounted optical tube assemblies (OTAs) and binoculars. The Porta II mount head is detachable and compatible with all other Vixen tripods. The tripod is constructed from rugged aluminum alloy, and the legs extend from 35 to 51".

    No locks or clutches
    Portable alt-azimuth mount with precision slow-motion control in both axes
    Slow-motion control with whole circle movement via 120-tooth wheel gears
    Tripod legs height adjustment: 35-51"
    Mount can be removed and used on heavier tripod if needed.
