Why are refractors better for astrophotography?
Refractors are compact and lightweight compared to other telescope designs. The focusers are solid and easy to focus. They offer a similar experience to a high-end telephoto camera lens. The image quality potential for astrophotography is exceptional.
What does APO mean in telescopes?
An apochromat, or apochromatic lens (apo), is a photographic or other lens that has better correction of chromatic and spherical aberration than the much more common achromat lenses.
What can you see with a 80mm refractor?
The 80mm objective lens and short 400mm (f/5.0) focal length are perfect for taking in wide swaths of the heavens, making it ideal for larger deep-sky objects. You’ll see spectacular star clusters, wispy nebulas, and expansive galaxies with this telescope, but it also excels at viewing objects in our solar system.

What is a ED APO refractor?
Apochromatic (APO) lenses are designed to bring three wavelengths of light (red, green, and blue) into focus in the same plane. In contrast, achromatic lenses are corrected to bring two wavelengths into focus in the same plane.
What can you see with an 8 inch telescope?
This size scope, however, is a bit small for deep-sky objects such as nebulae, star clusters, and galaxies. An 8-inch telescope (it doesn’t matter what type) will move you into a new dimension of viewing. The objects you see with an 8-inch scope will reveal more detail.
Why do refractors have better contrast?
The overall contrast of refractors will tend to be higher. A refractor is likely to have an optical system of higher accuracy and so closer to optical perfection. The reason is very simple. It is actually four times easier to make a lens with a given optical precision than a mirror.
