Tele Vue-60 60mm, f/6, APO (Doublet) Refractor
The compact, portable TeleVue TV-60 60mm f/6 apo body is perfectly designed for its objectives, and executes them in a quality, attractive package. The TV-60 has been updated to address a few imaging issues, and maintains all of the benefits of a great 66mm aperture scope. First and foremost, the TV-60 is an ideal on the go scope. Weighing in at a little under 2kg and a bit longer than 25cm, the smallest in the TeleVue line defines portability.
The sheer size of it alone is almost enough to add to your collection, as it can be taken just about anywhere for your observational and imaging needs. It also features a balancing bar with a dovetail mount and it fits all SCT brackets. This is an important part of the TV-60’s versatility, since it can be used for a wide range of uses. It feels perfectly comfortable as a spotting scope, guide scope, viewfinder, observational scope or telephoto lens.
All of this is possible because of the TV-60’s construction, as it doesn’t sacrifice performance for size. First of all, it is important to understand the limitations of a 66mm aperture, but in that class of scope, it offers surprisingly striking images. In fact, the most surprising aspect of the image is the wide field attributed to its doublet refractor, creating a 4.3 degree field of view.
Everything about the scope is tuned for its small size. The 360mm focal length perfectly compliments the 60mm aperture, creating a high-quality image in all of its many uses. The scope is completely capable of its higher end of magnification recommendation of 180x, which equals 75x to every inch of aperture. The dual-stage focuser leads to responsive focusing of a quality image from such a compact design.
The modified refractor represents an advance in the TV-60’s design. Where before it created problems when shooting with a large CCD chip, imaging has been improved with a rear lens group enlarged to accommodate these chips. The additional field flattener answers the issues that most seriously plagued the capability of the scope as an imaging device.
The only lingering sub-par quality elements are the carrying case and lens cap, but overall, the TeleVue TV-60 shines due to its go-anywhere versatility
Tele Vue-76 76mm, f/6.3, APO (Doublet) Refractor
The Tele Vue TV-76 3″ telescope is ideal for the amateur astronomer looking to easily bring his telescope along on stargazing outings. With a body of only 14.5 inches this telescope can easily fit in any backpack, and at 7 pounds it won’t put any undue strain on your back. It also comes with a five year warranty. For all it’s small size, the TV-76 packs a big punch: a 160x largest usable magnification. It can be used on a normal photo tripod for informal usage, or an equatorial mount.
The TV-76 comes with a two inch mirror diagonal, which allows for use of 2 inch or 1.25 inch eyepieces. The 20mmm 1.25″, 24x magnification TeleVue Plössl is standard equipment. The exit pupil is 3.2 mm, which is highly useful in deep space observation. It has a visual limiting magnitude of 11.9, a 480 mm focal length, a resolution of 1.52 arc seconds, and a three inch aperture.
Astronomy magazine highly recommended the TV-76 in its September 2002 article. The authors’ praise ran from such diverse subjects as the moon, which they found to be incredibly sharp at all levels of magnification, and free of glare or false colors, to planetary views. The magazine found that they could easily pick out small color differences between Jupiter and Saturn, and see the moons of each. In good conditions, the authors could even see Jupter’s atmospheric belts and the separation in Saturn’s rings caused by Cassini
The TV-76 is a wonderfully flexible instrument which will enable you to gaze in wonder at both distant nebulae and our own moon. You can even use the built in adapter to take pictures of your findings. The magnification power of the TV-76 is amazing- some users have even reported being able to clearly view the complete North America Nebula and the Cygnus group, for example. Nowhere else will you find such a powerful telescope in such a small package.
