Slow telescopes have a focal ratio of f/8 or higher. They have shorter focal lengths (the distance between the eyepiece and the lens), which also makes them lighter and easier to carry. These models are fast and have a wider field of view, making them more suited to deep-sky photography. A smaller focal ratio, those below f/5, indicates a faster telescope in that it gathers light at a faster rate than a model with a slower focal rate. The resulting number is the f/number, such as f/4 or f/11. The focal ratio is the telescope’s focal length divided by the aperture. Keep in mind that although a telescope may come with one kind of mount, you can buy a different mount separately.

Automatic equatorial mounts are more expensive, but they leave you free to change eyepieces or take photos.
In comparison, an alt-azimuth mount requires adjusting two axis while you’re trying to track the object. These mounts require only one axis adjustment to follow the object. One of the best options for astrophotography is the equatorial mount. Without the right mount, you can end up with blurred images or images with a visible trail. Mount importance comes down to the fact that the Earth is rotating, which alters the location of the object as you’re taking a photo. The mount is especially important if you want to take long exposure (slow) images. Things to Consider Before Buying a Telescope for Astrophotography Mount Typeīefore you invest in a telescope, consider what type of mount you already have or the mount that comes with the telescope. You can use this telescope for viewing deep-sky objects, but your chances of getting a good photo at those longer distances aren’t great with this model. The optical specs, including a 1.45 Dawes limit, 1.75 Rayleigh limit, and 12 limiting magnitude, squeeze every last ounce of optical quality, especially in a tube this size. At only 7.3 pounds, you can take it to the local mountaintop for a broader range of spectacular views as you escape light pollution. However, for advanced beginners, intermediate, and even some advanced astrophotographers, the EvoStar 80 provides the quality and ability to travel with the telescope. Consequently, this isn’t a model for beginners. However, attaining that quality may require the purchase of a few extra accessories. The Sky-Watcher EvoStar 80 APO Doublet Refractor offers an impressive array of optics that create vivid detail and image quality. Includes only the tube with a few accessories
CA stays controlled with the doublet and moderate focal ratio Lets you delve into professional-quality astrophotography We picked telescopes based on the quality of their build, their optics, field of view, and focal ratio. Best Overall: Sky-Watcher Skymax Maksutov-Cassegrain Reflector Telescope - Best for Deep Space: Explore Scientific ED127 Triplet Refractor Telescope - Best Portable: Sky-Watcher EvoStar 80 APO Doublet Refractor - Best for Beginners: Celestron 114LCM Computerized Newtonian Telescope - Best Budget: Celestron AstroMaster 130EQ-MD Newtonian Telescope How We Picked the Best Telescopes for Astrophotography Methodology Take a look at our list of the best telescopes for astrophotography for the models that fit different gazing and astrophotography goals, budgets, and portability needs. However, there are a few budget-friendly models worth considering as well. You can easily spend well over $1,000 and will probably spend at least that much for a model that results in high-quality images. It’s also important to start with a budget in mind. Interplanetary photos are a different ball game, too. A telescope that details the moon’s every last crevice is different from a model that lets you make the Andromeda Galaxy your next piece of wall art. Your choice of telescope comes, in part, down to what kind of astrophotography you want to do.
Some stargazers are happy to look, while others want to save far-off galaxies for the future with the best telescopes for astrophotography.
