So, a 100mm aperture is 56% brighter than a 80mm aperture in terms of the amount of light gathered.) (Remember, the aperture’s light collection ability is the function of the square of its diameter. The EvoStar 100mm APO refracting telescope (where APO is short for apochromatic) offers excellent brightness and image quality with a number of advanced optical features.įirst, the 100mm objective lens is large enough to gather a ton of light compared to most refracting telescopes – producing bright and clear images.

This equatorial mount can also be upgraded with the EQ-2M electronic motorized drive for automatic tracking. The equatorial mount includes slow-motion control and is ideal for tracking celestial objects. Second, it features a manual German equatorial mount and tripod which is heavier than the typical starter telescope. Due to its large aperture, it can also be used for deep-sky viewing in the right conditions. The 90mm aperture allows for stunning, high-contrast, detailed views of the moon, and it offers superb planetary viewing. and it’s almost 5′ tall when fully assembled. This 90mm refractor from Orion offers an excellent value, and it’s a huge step up from many of the beginner refractors you’ll see in 80mm range and below.įirst, this is not a starter telescope by any means – it weighs 25 lbs.
