It would be nice to skip that spacing (as long as I'm not using the f/6.3 reducer) -- to make clearing the mount base much easier at high elevations. With a computerized scope, each time you start a new observation, you need to enter your current local time, the date, and your location. Bought the Celestron f/6.3 reducer. Made some attempts at DSOs with the asi120 which was awful obviously. The reducer itself is ok I guess. Alternative models: The Unistellar eQuinox 2 is up there amongst the best GoTo telescopes and is well worth your consideration. If you've got a tighter budget, give the Celestron NexStar 4SE a look: it uses the same SkyAlign software as the 6SE but comes in at a much lower price.

Mounted to the optical tube is also a red dot reflex sight for aiming in the sky. The build quality is not the greatest, but it suffices for simple star alignment before enabling the NexStar’s go-to. What Can You Observe Through The Celestron 6SE? At Rother Valley Optics, one thing we pride ourselves on is customer service and quality of our equipment. When we test your telescope, we will ensure that it is of the highest quality otherwise, we will reject the scope under our strict quality control and test another model for your peace of mind. One of the main values to look at when testing a refractor is the Strehl ratio. The higher this number, the higher quality lens you have. At Rother Valley Optics, we will guarantee the highest possible Strehl ratio for your telescope. We will aim to provide 0.95 Strehl or higher on Takahashi, RVO Horizon, William Optics and many more! Generally, the higher the Strehl ratio, the lower the Astigmatism and Coma meaning a better image quality from your instrument. Don't buy if: You're an absolute beginner looking for a cheap first telescope, or are a purist not wanting a GoTo scope. With your fingernail on either side of the battery, pry the battery up and out of the battery compartment.

Celestron Nexstar 6SE review

The NexStar 6SE is one of the more expensive amateur astronomy telescopes you can buy. It’s also one of the most advanced.

SkyAlign is advertised as being super easy to use. Still, whether it is a user error or a focusing issue, sometimes the program does not work as intended, which can delay or throw off your plans to have a computerized viewing session on a given night. I "think" at this point I understand well what is needed to create the image train when using the f/6.3 focal reducer (getting to the 105mm spacing). Thanks to its small size, the C6 doesn’t really suffer from the mirror flop problems that plague larger Schmidt-Cassegrains nor have a particularly narrow field of view. That being said, despite being physically compatible with a 2” diagonal, the C6 cannot actually illuminate the field of view of a 2” low-power eyepiece and will vignette quite badly with an f/6.3 reducer. Thus, the scope isn’t going to provide a field of view much larger than 1 degree (about 2 full moons)-which means it isn’t ideal for wide-field vistas of star clusters and nebulae, though a 1-degree field is still plenty big to satisfy most users. Despite its smaller aperture and somewhat narrow field of view, many deep sky objects can be seen in detail. Large globular clusters are an exciting view under dark skies, as well as some of the brighter galaxies like M51, M31, or M33. The long focal length of the 6SE also allows for the observation of small planetary nebulae, such as M57, Caldwell 39, or Caldwell 63. The 6SE comes with a single eyepiece – a 25mm E-Lux Plossl providing 60x. It’s a good starter eyepiece for low magnification, but as with any telescope, you’ll want at least a few extra eyepieces to provide a range of magnification options.

The Celestron NexStar 6SE is the 6-inch model, which obtains up to 44% more light than previous (5 inch) model.
