Telescope Review

• Meade Model #591 6" f/8 (Reflector)

This model has a newer version in Starfinder 6  which costs on the average, about $600.  Images appear smooth. This is highly recommended for general terrestrial viewing. Suitable for neophyte astronomers.  

• TeleVue Ranger , 70 mm f/6.8 (Refractor)

Highly flexible telescope;  the focuser allows you to fine-focus on an image, the draw tube elicits rough focus.

• Celestron Cometron 90 mm  (Reflector)

Introduced in the market in 1986 just in time for what many perceived as the monumental visit of the Halley’s Comet.  The optics are good and the unit comes with a tripod, but this is not recommended for amateur stargazers; for images to appear vivid, fine tuning is required.  Not the “shoot and focus” type.

 

• Meade DS-10, 9.25 mm  (Reflector)

     As far as optics are concerned, these are good but the instrument
     is built in such a way that you will not have much flexibility in
positioning it:  the mount is close to the ground and the tube does not rotate.

• Orion Short Tube 80 (Refractor)

Reasonably-priced for a telescope suitable for viewing nearby nebulae and other terrestrial objects.  It can give you a better vista of the Milky Way .

Sometimes a halo-effect appear on very bright objects but these are minor aberrations.  In the overall, the scopes are excellent, they can even be converted into a microscope, with slip-ons corrector type of lens, of course!
