How good is a Bushnell 150×50mm Refractor Telescope?

First the 150 x is deceptive. Any telescope is limited to 50 x per inch of aperture. Beyond that, it just gets fuzzier.

50 mm is two inches (about) so 100 times is the most you can hope for. 30 times is a more realistic number because you want to enhance light gathering also. The higher the magnification, the dimmer the image. Stick to the 20 mm eyepiece and this scope will serve as a beginner instrument.

Yes you can see Jupiter as a visible disk and even the four biggest Jupiter moons, tho they will just look like points of light. Neptune is well within its reach BUT since Neptune is barely visible to the naked eye, it is much harder to find than Jupiter. Since this telescope has no directional aid Cheap VPXL Online Without Prescription or finder scope, Neptune will be difficult. Mercury, Generic viagra whithout prescription Venus and Mars and Saturn are all within reach of this telescope. Star clusters like the "Bee Hive" and M13 (a bright globular cluster in the constellation Hercules) are within the reach of this telescope.

A reflector telescope gives far more bang for the dollar than a refractor telescope. Reflector  of 110 mm diameter and 900 mm focal length will allow a solid 200 times magnification.
