Like many Celestron GoTo telescopes, the Astro-Fi 130 is powered by 8 AA batteries in a small pack attached to the side of the tripod. Powering the Wi-Fi network will drain these faster compared to a regular, controller-operated telescope, so I would definitely recommend using AC power or a rechargeable 12-volt DC power supply.
I find this to be an improvement over the usually useless metal or plastic spreaders provided with many scopes which do nothing besides serve as a slight structural support. Lastly, the spreader has completely changed in design, having a shelf (presumably for your phone) and some rubbery gripping substance on it.
Read why we prefer High Point Scientific to Amazon Slewing it is dead simple – the only complaint I have is that it takes a bit to move all the way around the sky even at maximum slewing speed.īuy From HighPointScientific Check Amazon Listing There is far less backlash compared to most Celestron mounts. However, it is a completely different beast.įor one, the gears in the mount head seem to have been improved compared to the NexStar SLT. About the Astro-Fi MountĪt first glance, the Celestron Astro-Fi mount outwardly resembles Celestron’s NexStar SLT and GT mounts. This adapter is rather crude, but it does function better than merely holding your phone to the eyepiece. I’d much rather have them than cheap, plastic Plossls.Īdditionally, the Astro-Fi 130 includes a StarPointer red dot finder for aligning the scope and newer models include a smartphone adapter built into the lens cap. While they do lack eyeguards and don’t work the greatest at f/5, they’re all-metal in construction and are decent for a sub-$350 telescope. The Astro-Fi 130 comes with 25mm (26x) and 10mm (65x) Kellner eyepieces. We recommend checking out our collimation guide to learn more about this process. Thus, if your scope doesn’t come with the aforementioned adapter and you wish to use 2” eyepieces with it, you may need to 3d-print or otherwise manufacture your own adapter to make this possible.Ĭollimating the Astro-Fi 130 might be a little difficult for a first-time user, especially since the telescope doesn’t include a collimation tool out of the box. When I called Celestron customer support about the lack of the 2” adapter on the latter, they told me they knew of no such part in existence. This focuser is a little confusing – it is technically capable of fitting a 2” eyepiece, but Celestron doesn’t seem to always supply an adapter to make this possible – one 130 I received had one while the other did not. The noticeable difference of the Astro-Fi 130 compared to many other 130mm Newtonians is its 2.5” rack-and-pinion focuser, which it only shares with Celestron’s other 130mm computerized telescopes – Celestron’s NexStar 130SLT and SkyProdigy 130. With good collimation and air seeing conditions, Celestron Astro Fi 130 can handle magnifications up to 260x, though you’ll probably want to use less than that on everything except perhaps the tightest double stars on the best of nights.

The f/5 focal ratio also enables a relatively wide field of view: 2.1 degrees (over 4 full Moons across) with the included 25mm Kellner eyepiece, over 2.5 degrees with a widest-field 1.25” eyepiece, and up to about 3.5 degrees if you can adapt a 2” eyepiece to it. These all tend to have good optics, and the 5.1” of aperture is enough to begin delving into serious deep-sky observation as well as lunar and planetary viewing. The Astro-Fi 130’s optical tube is identical to most 130mm f/5 Newtonians on the market.
