Orion 120mm f/5.0 Refractor OTA

Are you looking for a refractor telescope body that's short on length and long on light grasp? The the Orion 120mm f/5.0 Refractor OTA is right for you.

This compact, large-aperture Orion 120mm F/5.0 Refractor Telescope Optical Tube is perfect for deep-sky pursuits. Its 120mm (4.7"), multi-coated achromatic telescope lens assembly and modest 600mm focal length combine to provide breathtaking wide-field views. With an optional 25mm Plossl telescope eyepiece, this telescope serves up a sprawling 2.1-deg swath of sky! The fast f/5.0 optical system also makes it an excellent telescope for astrophotography. The 26"-long optical tube is well baffled to ensure good contrast. The cast-metal 2" rack-and-pinion focuser accommodates either a 1.25" or 2" diagonal, so you can use 1.25" or 2" telescope eyepieces. Tube color is gunmetal gray metallic. A mounting base molded into the focuser casting to accept an optional Orion finder scope or EZ Finder II.

For those who already have the amenities like finderscope, eyepieces, mount and tripod - this is a dream come true. You don't pay extra for what you don't need. Perhaps you'd rather customize the way your scope is built from the ground up? Again, the Orion 120mm f/5.0 Refractor OTA is what you're looking for.

This small, high quality refractor is a winner all the way around!

120mm f/5.0 achromat
I'm using this fast achromat for deep sky imaging. I increased the focal length to 750 mm with a 1.5 x barlow and gave a nice image scale to the Dumbell Nebula (M27. The chromatic aberration effects present in achromats could largely be removed in post-processing of the image that I took. The image of M27 I took with this scope is here: http://revans_01420.webs.com/apps/photos/photo?photoid=54917719

Overall I would give this scope 5 stars because of its reasonable price and its potential capabilities. Good deep sky imaging is within reach with this scope, but some post-processing to remove violet halo's etc. will help a lot with an impressive final image.
