Description: Aficionados of fine optics know how good a deal these no-longer-made Maksutov Newtonians were. The small 19.7% central obstruction produces refractor-like performance. It can handle both wide field coma-free views as well as high power planetary observation. This is the perfect scope for Mars. The optics are smooth and the scope star tests very well. I've attached the star test images.

Our 5.5" (140mm) Maksutov-Newtonian delivers high-contrast, aberration free images. Fast f/5.4 focal ratio (756mm focal length) excels for CCD and DSLR imaging. More affordable than apochromatic refractors of comparable aperture. Low-profile 2" Crayford-style focuser (with 1.25" adapter) minimizes vignetting. OTA includes tube rings, mounting plate, finder scope base, case, and one-year limited warranty.

JMI Focuser Model 3 for Newtonian Telescopes
Although the EV-3c can be plugged into the telescope's base allowing control from the Meade hand unit, you will have better control with the JMI hand unit. Our hand unit includes an electronic brake (not included in Meade systems), which stops the motor as soon as you quit pressing the keys, and linear voltage control for superior speed control. Also, older LX200 telescopes do not have enough power to properly run the motor on the low setting.

10" Primary Mirror Heater for Newtonian Telescopes. The heaters have been built to use only as much power as necessary and thereby not waste energy. They have sponge insulation on one side to prevent heat being lost into the atmosphere. The heat is directed into the optics instead and because of this, less energy is needed to keep your optics moisture free.

Lumicon 1.25" Newtonian Easy Guider One of the most powerful astrophotographic accessories on the market today for Newtonian Telescope photography - the low-profile 1.25" LUMICON® NEWTONIAN EASY-GUIDER. The easy-to-use Lumicon Newtonian Easy-Guider incorporates a unique, patented, radial adjustment for finding bright, off-axis photographic field guide stars. The Lumicon Newtonian Easy-Guider has not only radial, but rotational adjustments, along with a large off-axis pickoff prism that helps make bright guide star selection a breeze. The Lumicon Newtonian Easy-Guider uses your Newtonian telescope optics directly for superior pinpoint guiding accuracy. Never again will your guided photographs be ruined by differential flexure that leaves star trails. The filter compartment for the 1.25" Lumicon Newtonian Easy-Guider is located above the plane of the pick-off prism - that is, on the camera side of the Easy-Guider, thus allowing you to guide with unfiltered starlight. Only the camera light is filtered - a rea

Baader 2" Multi Purpose Coma Corrector for Newtonian Telescopes
The MPCC has been optimized for Newtonians with focal ratios from f/4 to f/6, and will deliver 12micron stars across a full 35mm frame size. Independent optical laboratory tests (by ITE) have confirmed that the MPCC is the sharpest wide-field coma corrector available for imaging, and provides the best edge of field illumination. Visual users have reported great results even down to f/3.7. The optics are anti-reflection coated with the finest 7 layer multi-coatings available. The MPCC is also priced...

Baader Planetarium has added a unique innovation to the laser collimator. The Laser Colli incorporates a viewable etched viewing plate which can be seen through the back of the laser collimator. This permits collimation of SCTs and small diameter closed tube Newtonians, instruments that were difficult or impossible to collimate using a conventional single beam laser collimator.

Newtonian Reflector Telescopes The Registry of Nature Habitats - Buy Conservation Credits
Freedom from most optical aberrations and delivery of very bright images. Reasonably compact and portable to focal lengths of 1000mm. Excellent performance observing faint deep-sky objects such as nebulae, remote galaxies and star clusters. Lowest cost per square inch of aperture due to use of mirrors rather than lenses. Generally fast focal ratios: f/4 to f/9.
