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.
Similar to their Schmidt cousins, this VMC95L 95mm f/11.1 Maksutov-Cassegrain Telescope from Vixen Optics exchanges the Schmidt's 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 and imaging.
The scope is outfitted with a 1.25" eyepiece holder set on the top with a dedicated camera port in-line with the OTA that accepts an array of optional equipment to mount a variety of cameras and imaging systems. An internal 90° flip mirror allows you to observe your subject, then flip the mirror down to image it. This dual capacity eliminates the need to remove and install equipment which not only slows the imaging process down but also increases the chance of accidentally moving the OTA and losing your subject. The OTA is offered here without a mount or tripod for users that have a platform, or want to use it as part of a dual-OTA set up for star-parties. It is supplied with a 25mm Plossl eyepiece that yields 42x magnification, a red-dot finderscope, and a Vixen-style dovetail plate for compatible saddles. This OTA's compact form-factor belies its observation power and resolution and is not only a competent imaging scope, it is also ideally suited as a grab-and-go option for quick observation sessions or heading out to remote locations.

Porta II Altazimuth 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 35-51". The Porta II minimizes support-system oriented frustration when searching 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 OTA 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 35-51".
