telescope eyepieces?
Can some one please tell me why telescope manufactuers include 4mm or stronger eyepieces with their scopes smaller than a 6inch scope.I,ve got a 90mm meade with 1000mm f/l and when I use the 4mm eye piece I can't get a good clear image because the little 3 1/2 inch lense doesn't gather enough light to support it...Sorry for the rant but it just makes me mad that they add the higher powered eyepiece so they can promote a higher magnification rate.....
The maximum usable magnification for a given Telescope is approximately 50 times the aperture diameter in inches.
Your 90mm (~3 1/2") telescope has a maximum usable magnification of around 175X. Under Excellent conditions!!!. ( which in my neck of the woods happens about a handful of times a year) The 4mm eyepiece produces a magnification of 250X !!, way over the max limit. As a consequence, the image is very blurry and gets worse as magnification increases. These high mag eyepieces are pure Hype and are included solely for the purpose of advertising." 675 Power Telescope" sounds good, but is truly nonsense.
I always tell folks: " whenever you see a telescope advertised by it's magnification, run the other way"
Most folks get the best views around 20X to 40X times the aperture in inches. For your telescope, get a good quality eyepiec of around 10 to 12mm focal length, it will be the one you use most often.
Also, get a decent eyepiece of around 30 to 32mm focal length for wide field views and to use when trying to find stuff in the sky. It's wide field of view make it much easier to locate things.

Orion SpaceProbe 3 Altazimuth Reflector Telescope
Sale Price: $99.99 |
DescriptionOrion's surprising little Spaceprobe 3 has been picked by independent reviewers as one of the best telescopes in its price class. Unlike similar telescopes seen in discount stores, Orion has refined the Spaceprobe 3 by paying attention to the little details, and that make this telescope a great value. The Spaceprobe 3 comes with an unusually complete set of accessories. The package includes two very good Explorer II eyepieces (25mm and 10mm), an adjustable altazimuth tripod, a good red-dot finder, a student edition of "The Sky" planetarium program, and a well written manual. The package even includes the tools you'll need to assemble the telescope and align the optics. The Spaceprobe 3 is a Newtonian reflector. That means it uses mirrors instead of lenses. Newtonians are primarily used for astronomy because the images are upside-down. Orion includes a collimation tool and good directions for aligning the mirrors. The reward for aligning the mirrors is seen in images that snap into sharp focus. My Spaceprobe 3 arrived properly aligned right out of the box. With its Explorer II eyepieces, this telescope consistently delivers fine views. Using the 25mm eyepiece (28x magnification) the Pleiades cluster is simply wonderful, showing dozens of stars. From a rural location with a dark sky, the Orion Nebula is a big ghostly glow, and when I zoom in with the 10mm eyepiece, the Trapezium resolves into four tiny pinpoints. The double star Gamma Andromeda becomes two beads of light, one gold, the other one pale blue. Moon and planet images are crisp, with none of the false color I see in low cost refractors. When I look at the Moon I see mountains and terraced walls inside the larger craters. With the 10mm eyepiece (about 70x), Saturn's rings are sharply separated from the planet, and I can even pick out the planet's shadow on the rings. The Altazimuth mount included with this telescope is light and easy to use; it may be the best choice for a young astronomer. If you want motorized tracking of the stars and planets, Orion's Spaceprobe 3 EQ is available with an equatorial mount, and Celestron sells essentially the same optical system with the computerized NexStar 76GT. -Jeff Phillips Pros: Best in class optical performance Two good Explorer II eyepieces Complete accessory package Cons: Small 76mm aperture Upside-down terrestrial images If you're looking for an affordable entry-level telescope for that beginning astronomy enthusiast, our SpaceProbe 3 Altaz is the perfect choice. Great for all-around stargazing, this highly portable, uncomplicated scope is just the right size and weight for the entire family, and just the right price for parents. This is a quality telescope, with a 3" (76mm) glass primary mirror mounted in a sturdy Neptune Blue Metallic aluminum tube. The rack-and-pinion focuser accepts standard 1.25" eyepieces. Two Explorer II eyepieces, a low-power 25mm (28x) and a high-power 10mm (70x), are included. An EZ Finder II finder scope mounted on the tube helps zero-in on the sky target. The altazimuth mount is lightweight and easy to use. To aim it, simply move it up or down or left or right. An adjustable, aluminum tripod with accessory tray is also included. One-year limited warranty. Features

Orion Observer 70mm Equatorial Refractor Telescope
Sale Price: $169.99 |
DescriptionOrion’s Observer 70 EQ combines the solid optical performance of a classic achromatic refractor with a German style equatorial mount. The Observer 70 features very good optics and 36 percent more light gathering power than 60mm beginner scopes. The complete accessory package includes high and low power eyepieces, a 90 degree star diagonal, a red-dot finder, illustrated instructions, and Orionâs Starry Night Special Edition astronomy software. The Observer 70 EQ features very good optical performance. Achromatic refractors have a two piece objective lens, the second lens element compensates for “chromatic aberration”, the false color or blue fringes seen in low cost telescopes. In daylight tests I see very little blue fringing with the standard equipment 10mm eyepiece (70X magnification), and none at all with the 25mm eyepiece (28X). Stars and planets show up very nicely with the Observer 70. The quadruple star in the Orion Nebula known as the Trapezium is cleanly split into four components with the 10mm eyepiece (70X magnification). When I combine the 10mm eyepiece with a 2X Barlow lens for 140X magnification, I’m treated to lovely views of Saturn’s rings and the little orange disk of Mars. My view of the Moon is delightfully crisp and clear; the 25mm eyepiece nicely frames the Lunar disk, and using the 10mm eyepiece I can easily see mountain peaks and terraced walls inside the crater Copernicus. The Observer 70 EQ also features an aluminum tripod and an EQ-1 equatorial mount. The equatorial mount is a little more complicated to balance and align than the Observer 70 AZ , but the reward is better slow motion control and tracking at magnifications over 100X. Simply point the equatorial axis at Polaris, the North Star, and the telescope tracks celestial objects by turning one slow motion knob. This makes it much easier to use a high power eyepiece while viewing the Moon and Planets. The “EZ Finder II” works by shining a red LED on a small window; just look through the window and line up the red spot with your target. This works OK for bright objects like the Moon and planets but not so well for finding galaxies and deep space objects. Orion’s Observer 70 EQ is simply a very good entry level telescope for a student or family. The good quality 70mm optics produce an image that is significantly sharper and brighter than 60mm beginner scopes, and the package includes a solid mount, two good eyepieces, and fully illustrated instructions. --Jeff Phillips Pros: Reliable refractor design Good views of the Moon and planets Complete accessory package Starry Night software included Cons: Finder only works for bright objects This tried-and-true refractor goes the extra distance in introducing the novice to the wonders of the night sky. The Observer 70 features a 70mm fully anti-reflection coated achromatic objective lens, which provides 36% more light-gathering ability than a 60mm. Its 700mm focal length (f/10) will show you the stark beauty of the lunar surface, Saturn's rings, Jupiter's atmospheric belts, or the billowy clouds of the Orion Nebula. The included EQ-1 equatorial mount comes equipped with dual slow-motion controls for manual star tracking and adjustable aluminum tripod. Includes an EZ Finder II finder scope to help you zero in on your celestial targets, two eyepieces - 25mm (1.25") and 10mm (1.25") - and 90-deg star diagonal. One year limited warranty. Features
