![]() You’ll notice that each of these so-called sentences is not a complete sentence. Because they are hairy and frightening with large, pointed fangs and shiny, yellow eyes.The haunting of the house on the craggy hill just outside of town.Sometimes, a fragment is simply a dependent clause punctuated like a complete sentence. ![]() Sometimes, fragments are missing a subject. To put it simply, a sentence fragment is an incomplete sentence that you have punctuated as if it is a complete sentence. Sentence fragments always make the list of the most common errors, and they are among the most seriously stigmatizing errors we can make. You just have to recognize the error and figure out if you need to add a subject or a predicate, add it, and voila, it is fixed!įor the practice questions, no. Sometimes, they’re careless during the proofreading and editing process.īut, similar to run-on sentences, the good thing is that sentence fragments are easy to fix (well, they’re a tad more difficult, but not complex). Sometimes, they don’t realize that their sentence is incomplete. Sentence fragments are common grammar mistakes that many people make. ![]() If you found these questions helpful, you can find more of them (and ones with more detail and complexity) in workbooks, which you can find at my store here.

![]() ![]() You can replace the provided extension tube with one that uses a compression ring to provide a more secure, non-marring connection for 2” eyepieces, but for a $1000+ telescope, this is really inexcusable to have to do. Most well-made focusers and extension tubes use compression rings to grip your eyepieces, and the 1.25” adapter provided uses one and also has threads to install 2” filters on your 1.25” eyepieces-a nice touch. You should expect to have to collimate pretty frequently, though maybe not every time you set up the scope, but it’s not a particularly difficult process.Īs with the 8” model, the focuser on the StarSense Explorer 10” Dob is a basic 2” single-speed Crayford, which uses thumb screws to grip an extension tube (required for most eyepieces to reach focus) that also uses thumb screws. However, since no collimation tools are provided, you’ll need to make or purchase one separately. Unlike the 8” model, the StarSense Explorer 10” doesn’t require a screwdriver to adjust the primary mirror. This is important to keep in mind when shopping for eyepieces the cheap, poorly corrected wide-angle eyepieces practically thrown in for free with similarly fast scopes are better than nothing, but paying large sums for them to use with the StarSense Explorer 10” Dobsonian isn’t as logical, especially for a scope that already costs several hundred dollars more than the more well-equipped competition.Ĭollimating a faster telescope like an f/4.7 is slightly more difficult than a slower instrument. At f/4.7 focal ratio, “SuperView” or “SWA” eyepieces derived from the Erfle design have edge-of-field astigmatism and field curvature (making it look like you’re viewing at warp speed or from inside a fishbowl), and any low-power eyepiece with a true field much wider than the included 25mm Plossl eyepiece has obvious coma around the edges of the field of view.Ĭoma is easily ignored and often masked by other eyepiece aberrations edge-of-field astigmatism and field curvature are less so. The StarSense Explorer 10” Dobsonian is optically a 10” (254mm) f/4.7 Newtonian reflector with a focal length of 1200mm. In the case of the 10” model, whether this is an agreeable trade-off to you depends on how much you have in your total budget for a telescope/accessories, and whether you’re able to handle either the price and complexity of a 10”/12” truss tube telescope or the inconveniences of a massive solid-tubed 12” in lieu of purchasing the 10” StarSense Explorer. However, as with the 8” model, the StarSense Explorer 10” occupies the same price bracket as some scopes belonging to the next step up in aperture – a 12” – and lacks any of the features of “deluxe” or truss tube scopes at equal or lower prices.Ĭelestron is, in essence, charging hundreds of dollars for the privilege of a plastic bracket and an access code for a phone app with the StarSense Explorer telescopes. The StarSense Explorer technology makes locating “faint fuzzy” deep-sky objects a lot easier, without the complicated setup, power requirements, or price of a fully motorized GoTo system. The StarSense Explorer 10” reuses most of the components of the Sky-Watcher 10” Classic Dobsonian, which is essentially the same telescope but with a slightly different accessory package, a heavier base, and no StarSense Explorer bracket. Celestron’s StarSense Explorer 10” Dobsonian is the largest of the telescopes offered as part of the StarSense Explorer lineup, which also includes an 8” Dobsonian and various tripod-mounted telescopes of dubious usefulness and quality. ![]() |
