![]() Would appreciate any suggestions for something halfway decent that can aim high into the sky and is easy to use? Thanks in advance, Steve Steve, There's a pattern forming in this thread. I agree with the consensus - provided you're interested in _visual_ observation. I think you would be quite pleased with the performance and value of the Orion Skyquest Dobsonians; either XT-6 or XT-8. I would highly recommend going with the XT-8 (8") since it's solidly in your price range. (See links below) The reason is that although the 8" is only two inches in diameter bigger (33%) than the 6 ", the surface area (important for light gathering) will be roughly 56% more. And the 8" is still very portable; an important aspect many times overlooked by most eager new comers to the hobby. What good is an awesome scope that you won't use because it too much trouble take out the closet? And now is a good time to buy one. Orion is running a special offer which makes it a really sweet deal. They are currently upgrading the finder scopes from the standard 6X30 (6 power by 30mm objective lens) to a right angled 9X50. Bigger finders make it easier to locate faint objects and the *right angle* will flip the image. This is good because the finder itself flips the image once (makes every thing look upside down) so adding the right angle (90 deg.) mirror flips the image again making it right-side up. In addition, they throw in a Deluxe laser collimator (handy tool to have for aligning the telescope's internal mirrors, but will not substitute for some good tools and plenty reading - but that's a whole nother subject you will ask about later) and a very nice star chart. Oh and as was already stated, you get two eye pieces (they are actually pretty good for starters). You also get Starry Night for the computer (very nice) and a nice DVD (for TV) to introduce newbies to what's out there. Nice extras I think. *NOTE - The scopes addressed here or the Dobsonian species. If you think that you will want to get into photography, let the group know so that folks here can recommend a different scope. Dobs are great for viewing. Very stable. But they do not track the object. You will have to follow it as it moves across the sky (actually, it doesn't move, but is the Earth that's turning - but you knew that). You will be able to hold a camera to the eye piece and snap a photo or two of the Moon, Saturn, or Jupiter, but for really nice pictures, you need a scope that tracks. (Dobs can be made to track (not easily), but if your true interest is in pictures, it would be best to avoid them and buy a scope more suited for photography) The links below will take you to two versions of the 8" scope mentioned above. The Classic model with shipping will cost you about $400. That gives $100 for accessories. The XT-8 Intelliscope is computer assisted (a hand held unit plugs into the scope base and directs the user to 14000 celestial objects and will run almost $600 w/ shipping. Handy to have, but amateur astronomers are encouraged not to be computer dependent, but to learn the sky. If you fork over the extra cash for the object locator and learn the sky, you'll be glad in the long run you did both. The first accessory that you will want (IMO need) is a 2X Barlow. A barlow will double the magnification achieved by any eye piece used with it; plus add eye relief. Orion offers the Shorty and Shorty Plus, both also on sale; $31 and $61 respectively. I am not affiliated with ORION beyond that of being a very satisfied customer. Below are four links to the equipment discussed above. Two are repeats of the ones posted by Yo' Momma.

There's always the Stargazer Steve Dobs too and as an owner of one I know
it's a good scope. -- There are those who believe that life here, began out there, far across the universe, with tribes of humans, who may have been the forefathers of the Egyptians, or the Toltecs, or the Mayans. Some believe that they may yet be brothers of man, who even now fight to survive, somewhere beyond the heavens.

How does the telescope know where in the sky it is pointing? I am assuming you have to enter your exact location and the the date and time and it uses the same database that some of the web sites have, but it also has to know where it is pointing somehow. Just curious. Thanks for the tips. Steve |

Yes - unless it has a built in GPS, which will nake the location and time entry superfluous. It will then point to a couple (or three) bright stars in succession and ask you to line them up exactly and press enter. Once you have done that it's ready to find anything in its database.

Should I buy this telescope online or might I find it at a dealer? We are in North Jersey not far from NYC. Thanks! Steve |

You might consider setting the scope aside and spending some time to simply
learn the sky. You should be able to recognize the major constellations and bright stars the moment you step outside. There are lots of good books for learning the sky. I particularly like "Discover the Stars" by Richard Berry. -- Curtis Croulet Temecula, California 33°27'59"N, 117°05'53"W |

![]() Should I buy this telescope online or might I find it at a dealer? We are in North Jersey not far from NYC. Steve Steve, You will fair well regardless how you decide to purchase. I apologize in advance for the lengthily explanation and diarrhea of the mouth. If you buy from Orion, you will likely get the best price and gain the experience of assembling the telescope (gain insight on how your new telescope works). The assembly process will take anywhere from an hour to a few. If you follow the directions in the manual, you should be able to assemble it without any heartache. I assembled both my XT-8 and XT-12 intelliscope without much trouble. I used my XT-8 with great enthusiasm for over a year. After about a year, I bought a nice set of alignment tools and discovered that my scope, although performing very good, could be improved. The focuser was not exactly square to the OTA (outer tuba assembly - the main body of the scope) and secondary was off by a hair. I didn't have to correct them, but I was starting to loose sleep, so I corrected. Of course during the process of correcting, I put finger prints on my secondary mirror - so see how this business is.... Now here's a tip for you: Never touch your mirrors. Never work over the openings with tools that might fall and crash into one of your mirrors. When working inside the OTA, turn it horizontal. Always use extreme caution when working around your mirrors. You know what I do? I do like Ted Kennedy; throw money at the problem (he said that there was no problem in America that he couldn't fix by taxing the rich). I give the kids money and ask my wife to take them to Wal-Mart. No distractions. Problem solved. If you buy through someone like Company 7 (linked in Davoud's earlier reply), you'll pay a little more, but for the extra money, you'll know that your scope has been assembled by experts in the field. The reps at Company 7 will do a little tweaking here and there to make sure that the scope is in tip top shape. If I remember correctly, they charge $90 over the retail cost (Orion's price) to assemble and collimate. If you are not suave with a ruler , patient and articulate (and being that Company 7 is not far from you (approx 75 mi - don't know you exact location)), this may be your best route. Of course, collimating a scope is the art of carefully adjusting mirrors, one of which is mounted in a floating cell. My point is that if they adjust it perfectly in their shop, chances are if will need to be tweaked a little by the time you get home (shock and vibe during the ride home). Nonetheless, you will need to learn this regardless of who sets your scope up initially; them or you. *It should be noted that they (assuming you buy from Company 7) will check the alignment of the focuser, secondary mirror assembly, and mount the encoders. These things are sturdy and would not likely need to be repositioned. They come installed from the factory but know that these scopes are mass produced and that if it was made on a Friday (just kidding, I don't know what day is the last day of the work week in the Chinese factories, or even if they get a day off), yadda, yadda, and then it gets bumped during shipping. It will probably not be perfect when it arrives. But it will be close. Close enough to satisfy you until you're confident/willing to tear it down, square things up, risk ruining your mirror.... Enough about that. The primary will definitely need adjustment (need to be collimated). And it's the easiest of all the components to align (collimate). With a little practice, you will be able to do it within a couple of minutes _ in the dark_. Also, *how to collimate* has been discussed in this group more times than you can count. Search the group archives when you get to that point. If you still have questions, post them and you will get prompt help, I assure you. From time to time, the kooks post here. But some of the smartest minds in astronomy also post here. You will see. One more thing. I was told by an s.a.a regular (Jan Owen) to slow down and and research all the areas of interest before making a purchase. Good advice it was. For example, do you think that by upgrading, buying this 8" scope, you will be able see the beautiful, colorful images seen on the internet and in magazines? You won't. Many folks buy telescopes thinking they're going to get these big beautiful views. They meet with disappointment. If big colorful views of planets and nebulas and galaxies you desire, try hubble.org or .com, whatever it is. And contrary to its outward appearance, I am not trying to discourage you from adopting astronomy as a hobby worthy of investment. Quite the opposite. It is my opinion that one who has realistic expectations from the beginning, and learns _how to look_, and learns the science behind the objects and their movements, will be much more fulfilled than he who seeks out pretty pictures. To gaze upon light millions of years in travel. And once you learn to look, you will see plenty, e.g. rings within the rings of Saturn, surface detail like cloud bands and some moons (although they will appear as dots of light). You will make out colorful cloud bands on Jupiter along with the big red spot and some moons. You will see the craters on the moon with striking clarity. You will see, depending on your level of light pollution, a few nebulas and many star clusters, even a few faint (and I mean faint) galaxies. The key will be finding dark skies and still you will need to learn to see. The practice of letting your eyes dark adapt and learning to use your averted vision will come with practice. Check out this link on the subject. The light pollution map half way down the page is for your area. http://www.astropix.com/HTML/H_OTHER/SATPOL1.HTM Errol www.pasnola.org |

Just curious. Thanks for the tips. Steve The Intelliscope works a bit differently. Here is my simple, amateurish description of how the Intelliscope works. http://www.schlatter.org/Dad/Astrono...ope%20page.htm Once you have aligned your Intelliscope as described on my page, if you want to find a planet, the computer will ask for the date -- enter the date and the Intelliscope computer will calculate where the planet you are looking for is and will tell you which way to push the scope to find that planet. The Intelliscope is no substitute for "knowing the sky." You'll want to be able to find objects in the sky without the computer and you must be able to identify at least the major stars without the computer because you align the scope using two stars that you select. I use my Intelliscope computer about 1/3 to 1/2 the time, mainly to locate faint, fuzzy deep sky objects that I probably would miss otherwise. Remember -- the Intelliscope scopes ARE NOT MOTORIZED. The Intelliscope controller tells you which direction to push the scope up/down, left/right and it tells you when you are pointed at the object you have selected. The motorized scopes -- such as the Meade ETX scopes -- require you to enter date, time, and location -- and the time and location must be exact, that's why more and more of the GO-TO scopes are using a built-in GPS receiver to tell the scope the date, time, and location. |
