    Hi, Welcome to the astronomy forum.

    An Orion 130 ST EQ or a Celestron 127 EQ. Franky, I would not want either of these two telescopes. Why? Several reasons.
    1. Both of these telescopes are on a very weak mount and tripod that is subject to loads of vibration
    2. They are on an equatorial mount which serves little purpose but to add complications and cost for features you don't need and that they really can't provide ... Complications acquiring objects and complications viewing. .. Equatorial mounts move in strange ways and the eyepiece of a newtonian telescope gets in wierd positions.

    The Orion telescope is a traditional Newtonian with a parabolic mirror. The Celestron is a Bird Jones design and is technically a catadioptric scope with a spherical mirror and a corrector lens built into the focuser. The Bird Jones design is cheaper to manufacture.

    Given the choice between these two telescopes, I'd take the Celestron as it's price is about $100 less than the Orion. I don't see any particular benefit from the more expensive Orion other than it being easier to colliminate.

    For less money that you are planing to spend for the Orion, you can get a 150 mm Newtonian on a Dobson mount; the Orion SkyQuest XT6 Classic Dobsonian Telescope. A 150 mm telescope has sufficient aperture to see details on deep space objects, especially in a dark site. Its aperture is large enough to serve you for years; in fact, many people never get scopes bigger than 150 mm. Its Dobson mount will be rock solid, vibration free and an order of magnitude easier to use than the shakey German equatorial mounts on the two telesopes you mentioned. .

    For a $100 more, you can get Orion SkyQuest XT6i computerized Dobsonian

    I agree with sxinias, both are BAD choiches. Not because of bad optics but they both have hideous mounts.

    The orion scope is f5 so it explains its price.

    a dob is really a good choiche.
