Orion StarMax 90 Mak-Cass Telescope & Planetary Kit Feature

• This thorough telescope and accessory kit is outfitted for planetary viewing perfection at a vlaue price
• Long 1250mm focal length Maksutov-Cassegrain telescope with 90mm aperture provides plenty of magnification ability in a compact, tabletop package
• Included Color Filter Set enhances landscape details and cloudy features on the bright visible planets
• Included 7.5mm Sirius Plossl 1.25" eyepiece provides a high magnification view, with pleasing 52 degrees apparent field-of-view
• Included Shorty 2x Barlow Lens adds versatility by doubling the magnification of each eyepiece in your collection, also includes Starry Night astronomy software

Whoever coined the phrase "big things come in small packages", would have definitely applied that expression to our new StarMax 90 TableTop Refractor. This ultra-compact Mak-Cass gives surprisingly big views for an instrument of its modest size, making it an elegant first telescope or a great grab-and-go second telescope! The long, 1250mm (f/13.8) focal length gives the StarMax 90 TableTop some serious magnifying power - the included 25mm and 10mm 1.25-inch Super 3-element eyepieces yield powers of 50x and 125x, respectively. It collects over 25% more light than its GoScope 80 cousin, and up to 225% more light than a 60mm refractor telescope. So you'll be able to enjoy planetary delights such as lunar landscapes, Saturn's rings and Jupiter's moons. As you scan the Milky Way, you'll also be able to pull in some open and globular star clusters, as well as a nebula or two. The tube assembly of the StarMax 90mm TableTop Refractor Telescope is attached to a stable swivel base, via a quick-release dovetail mount with adjustable altitude tension. The tube can easily be removed from the base and mounted on an optional photo tripod. The small swivel base itself can also be mounted on a camera tripod with a 3/8-inch screw.

TMB Optical Planetary 4mm long eye relief 1.25" Eyepiece TMBP04

TMB Optical Planetary 4mm long eye relief 1.25" Eyepiece TMBP04 Reviews

Other Picture

This 4mm TMB Planetary eyepiece was designed to provide exceptional high power/comfortable eye relief observing with long focal length refractors, reflectors, or catadioptric scopes under average or better seeing conditions. It is optimized to view bright objects, both on and off axis, while showing maximum contrast, detail, and definition. It has very high light transmission, very high contrast, minimal lateral color, and minimal light scatter.

Combine the high resolution of the 4mm TMB planetary with its high contrast and you have an eyepiece that's unexcelled for lunar and planetary observing and binary star splitting. While the 4mm TMB eyepiece is optimized for observing subtle lunar and planetary detail and contrast, the eyepiece works equally well for splitting close binary stars, resolving compact globular clusters, etc. The 4mm focal length of this TMB provides very probably the maximum power possible with an f/10 Schmidt-Cassegrain, as it gives a very high 62.5x per inch of aperture with such a scope. That's more than the 50x-60x per inch of aperture considered the maximum possible under excellent seeing conditions. It provides the 0.5mm exit pupil recommended as the minimum usable for maximum detail with an f/8 focal ratio refractor or reflector.

Eye relief, at 10mm, is quite good for an eyepiece with such a short focal length. Vignetting will only be moderate for those who must wear eyeglasses while observing. This usually won't be a problem when using the TMB Planetary eyepiece on the kinds of objects for which it was optimized - planets, binary stars, etc. - as these small objects are generally kept in the center of the eyepiece field, where your eyesight is sharpest.

For Dobsonian users and others without tracking drives, the very low lateral color and other aberrations of the 4mm TMB allow a planet to drift across its entire 58 degree field while still being sharp and having high cont
