Reviews & Ratings for Celestron Omni XLT 150mm Telescope — 7 reviews — Page 1

A great "catch-all" scope that delivers value in a solid, excellent package.

I do want to take issue with another reviewer who bemoans about severe coma at very low magnifications with this scope...ANY f/5 optical system used at magnifications below about 30x or so will have severe coma at the edge of the field of view. This is an optical characteristic, not a defect or flaw in the optics, as is implied. You can buy eyepieces at considerable extra cost to nearly eliminate the coma, or just use a higher magnification. When collimated, the images in this scope will amaze you. A high-quality scope with easily adjustable optics.

2017: The mount is very stable and stays with target at celestial speeds with motor drive upgrades, in my case I purchased two drive motors. I don't experience any play with the drive motors and if there is play, Celestron website under troubleshooting tells you how to fix tight or loosen mount movements. The CG4 mount with drive motors also supports my NexStar 8SE OTA and I have taken nice pictures of Orion Nebula, IF you have your mount polar aligned, if not you will only have 5 seconds of stills before you see star streaks. For the price of this unit displayed here, its a very good bargain to build on and learn how to use your german equatorial mount. I can tell you this, to the naked eye, the 6 inch OTA Newt is very wonderful. I have taken this Newt to the dark hills of West Virginia, West By God Virginia and the Omni XLT 150mm delivered and stayed dead on with the celestial objects; stars and nebulas, drive motors can't follow solar objects.

I ordered this scope on Sunday evening and it shipped Monday morning. It was delivered by Friday.

So far it's been pretty cloudy around here, but I have managed some great views of the moon and Saturn, despite iffy conditions.
Pros: a great value, high quality optics, impressive looking-scope,
Cons: expect to need accessories pretty quickly: some form of collimator, shorter focal legth eyepice

Strengths:Solid mount; lightweight portable scope; comes to thermal equilibrium quickly; OTA has extra features including mirror adjustment screws and a nice finderscope; OTA performs very well at higher mag (85 to 112x)
Weaknesses: Suffers from severe coma at mag below 37x, a disapointment for wide field scope;supplied 25mm lens is useless
Comments:This is my sixth telescope, and I have side by side compared this scope to others including refractor, SC, and Dob newtonians. It compares favorably, and is an excellent scope at higher power mag, but falls down at low power mag,reducing its utility.As shipped the scope was out of alignment, and I worked hard to max alignment. To use this scope you must have an alignment tool, and preferably experience aligning mirrors.To get the most from this scope a variety of lenses are required, so plan on spending the money you saved on the scope, on a set of lenses. No polar alignment scope is provided, which is the only missing piece in an otherwise excellent value package.
Pros: Solid mount, many nice features on OTA
Cons: Severe coma below 37x; requires many lenses

For this being my first real telescope I couldn't be more happy! I can see things I didn't even know were there and when coupled with the motorized clock drive I can track objects from rise to set.
