Size
The Saxon F25412 HEQ-10 telescope has a 254mm lens. The telescope weighs over 10 pounds and is 36 inches long. The MG-B-0099 telescope has a 50 mm lens, weighs just over six pounds and is 34 inches long. The Saxon telescope is much larger than the MG telescope and has higher telescoping power due to increased mirror size.
Power
The Saxon telescope is much stronger than the MG telescope. The MG telescope is more of a hobby telescope. The Saxon telescope has the ability to magnify stars and planets 508 times and has a 1200mm focal length. The MG telescope has a 600mm focal length and can only magnify images 250 times.
Use
The uses for both telescopes are essentially the same. The MG telescope has less power, which makes seeing far-away planets difficult. The image in the MG telescope is less clear and does not allow as wide of a viewing angle. The Saxon telescope has a larger viewing window and can show planets and stars clearer and larger. The MG telescope is best for hobbyist who want to inspect stars at home. The Saxon telescope is strong enough for some basic astronomy use.
Cost
The MG telescope is much less expensive than the Saxon model. As of 2011, The MG telescope costs between $50 and $100. The Saxon telescope costs between $800 and $1200. The MG price point makes it better for those new to astronomy, while the Saxon model is best for individuals who have a keen interest in studying space.
