How to Buy the Best Telescope for Astrophotography
When in the market for the best telescopes for astrophotography, you will have to discern which elements are essential and which elements are just intended for marketing of a product. This will ensure that what you get is perfect for your needs, without being overwhelmed by too many specifications that have nothing to do with the effective use of the unit. Those vital considerations include the following.
Portability and Size
The best telescope for hobbyists is not always the largest on the market, although of course, the designers of the Hubble Space Telescope and the Keck twin telescopes will strongly disagree. However, if you intend to drive an hour or fly to a distant sky site, the weight and size of the unit can become extremely important.
This refers to the distance from the mirror or objective lens at which light is focused. Obtaining a larger image is possible with a longer focal length, signifying higher magnification as well. Spotting small objects such as double stars and planets is easier with increased magnification and longer focal lengths.
This denotes the relationship between the focal length and aperture. It is described as the focal length divided by the aperture, and defines the relative speed of the optical system. The faster the focal ratio, the faster the recording of an image.
Performance and Optical Design
A larger aperture allows collection of more light than an instrument with a smaller diameter. This enables the best telescopes for astrophotography to hone in on a larger number of objects with greater detail, and with adjustability to a higher viewing magnification.
Low-maintenance refractors deliver sharp, crisp images and are perfect for stargazing in moderately light polluted areas, the city or suburbs. Reflectors require periodic manual re-alignment of the optics. Cassegrains have a specialized or more advanced design combining refractors and reflectors to bend and reflect gathered light, giving them a long focal length.
Highest Rated Telescopes for Astrophotography in 2019
Prior to the purchase of an astrophotography telescope, you will have to do decent reading and research on such a highly technical piece of equipment. Don’t want to be bothered by reading too many product specifications and reviews? Take your cue from the three products described here to help you make an easier decision.
