A fine telescope

After aligning the mirror,this scope performed great. I had it out the night I received it,and even tho it was not a good night,I observed M13.Epsilon Lyra,and Jupiter. Jupiter was too low,and over houses,but in moments of better seeing,there was good detail. The scope star-tested very good. The mount is heavy,and works well,and is easy to use. I highly recommend this scope. It is a very good value.

Great value

I've used my Omni 150 for about 3 years. It's a sturdy well build product with good optics. I only wish I had the extra budget at the time of purchase to find a motorized goto mount.

Great value solid all-around performer

We researched telescopes very thoroughly before settling on the XLT 150, and couldn't be more pleased. It offers an outstanding value in the market right now, balancing light grasp, very high quality optics, versatility and ease of use in an affordable and still-portable package. The build quality and attention to detail is quite high, and it offers enough expandability to satisfy growing interests for many years. While no one scope can literally do it all, the XLT 150 comes as close as is reasonably possible. This is a scope that a beginner can use and grow into for many, many years, and is suitable for all ages pre-teen to adult. Younger children will need adult supervision, as with virtually all scopes in this performance class in our opinion. OPT has been outstanding with their level of service and expertise as well. We have been very pleased with our purchase experience. Disclaimer: We have no relationship with either Celestron or OPT other than being very satisfied customers. Clear skies!

Omni Potent

BIG BANG for the buck. Great low price at a profesional level telescope with high quality opticals and equipment mechanism. Very durable and very stable flatform. A good first telescope that you will not outgrow anytime soon.
