This is my first scope and it is awesome! It's very easy to use having the GoTo ability; image quality of the moon,Jupiter, Mars and stars is fantastic! The scope is simple to set up, light and easy to store if you're restricted for space.

Overall Score

Great first telescope, very detailed instructions. Allignment so easy with laser sight, quick setup & easy to use.

Only drawback has been the weather, it's been either raining or cloudy since I got it - so I haven't been able to play!

Extremely fast delivery and great service. Ordered another item from another ebay seller a few days before this telescope - telescope arrived 1 week earlier!

Thanks!

First telescope... - Review by
Overall Score
80
I chose this for my first scope, and so far have found it excellent for Jupiter, Saturn, the moon, star clusters and a handful of the brighter galaxies and nebulae. Aligning, finding and tracking objects is all very quick and straight-forward.

Keep in mind though that for the smaller size of the scope, some of the deep-sky objects in the database will simply be too dim to see without a very dark location. But for a first telescope that's easy to grab, set up and go take a look at the sky, highly recommended. :)

I was also very happy with the prompt, reliable dispatch and delivery.
