If you have a room with a view over the sea or hills from your window or are looking for an affordable telescope for astronomy, this 90mm (3.5") f10 refractor on an alt-az mount is a good choice. 

“Great deep-space views…. Using the 25mm eyepiece, the star Altair was sharp across 90 percent of the field of view, with only slight distortion close to the edges. Using the 10mm eyepiece we just split Epsilon Lyrae into four stars and Albireo had lovely gold and blue component stars. All our test nebulae and galaxies were easily viewed. The Dumbbell Nebula showed strong mottling and the the Andromeda Galaxy filled the view at low magnification, with its two companion galaxies also visible."

An excellent budget refractor for visual use
Tuesday, 17 May 2011  | 

I would recommend this refractor for a young person just starting out in astronomy. It immediacy of use and ease of movement makes it ideal for that purpose, or if preferred, a good grab and go telescope to take out to darker locations.

The supplied eyepieces are very poor; once you have upgraded to skywatcher plossls for example, you will start to enjoy the potential of this telescope. The moon looks crisp and clear with very little chromatic aberration. Jupiter's cloud belts can be seen. Although this has the reputation of being a decent planetary and lunar telescope, I have seen a few deep-space objects such as the Crab Nebula, which can be seen as a smudge and the wonderful Andromeda Galaxy and her neighbouring galaxies - a real treat to discover.

Exploring the magnification of this item, I tried to view the Trapezium stars in the Orion Nebula and was just able to see them at 180 times magnification.

The mount is adequate - solid enough to not worry about unwanted movement - however it can get a little stiff in very cold temperatures - I'm talking minus 10 degrees celcius and colder!

I have rated this telescope four stars due to the poor eyepieces and the occasional stiffness in the mount, which I have already blamed on exceptionally cold weather!

This is no bargain basement telescope - anyone who is getting into astronomy should be guided to these type of scopes, and should NOT buy the "entry level" types seen sold in Argos or Tescos! The owner can expect to enjoy some serious astronomy. Getting decent astronomical gear to sustain an interest in the night sky is vital.
