I liked Bill Greer's questions a lot and just thought Question number 9
should be added (see below). More suggestions are welcome! When we have 'consensus' on its contents, we should keep a copy of it somewhere. So if a regular S.A.A poster sees someone with the normal "Which telescope should I buy?" question, then he or she can reply with the questionnaire. Hopefully the original poster will go through the effort of answering it and send it back to the newsgroup. Then we can unleash our informed advice onto the poor soul! ;-) QUESTIONNAIRE Please answer the following questions to the best of your ability. Your answers will greatly assist us in directing you to the right telescope for your needs. 1) What price range are you considering? Would you be willing to spend more in order to get the performance you desire? 2) What would you like to be able to see? What specific details would you want to be able to see in those objects? 3) Would you eventually want to use this telescope for photography, CCD imaging, or any other specialized purpose? 4) What is the nearest city/town to the area in which you plan on using the telescope? How far from this city/town do you intend to set up and use your new telescope? 5) If size and weight are important factors, what are your approximate limitations? 6) Do you want the telescope now; or are you willing to wait for the right telescope? 7) Are there any specific features or capabilities you think you would want or not want in your new telescope? 8) Is there anything else that would be important for us to consider in order to direct you to the right telescope? 9) In which country do you stay? Some equipment manufacturers may not have distributors there. -- 25° 45' S 28° 12' E |

QUESTIONNAIRE Not a bad idea. However, I think most beginners will need help in interpreting and answering these questions. One way that we might be able to do this without requiring interaction (after all, we're trying to avoid some of that) is to put these questions on a web page, and hyperlink the questions to clarifications. 1) What price range are you considering? Would you be willing to spend more in order to get the performance you desire? I wouldn't be sure how to answer that second part. The problem is that I might not be sure what kind of performance I could get. We on SAA are familiar with the measurements of performance (light gathering, resolution, contrast, field flatness, etc), but a novice won't be. 2) What would you like to be able to see? What specific details would you want to be able to see in those objects? Again, what details are reasonable to expect? We should point out that lunar landers are unreasonable, but the rings of Saturn, and even some details in those rings, aren't. 3) Would you eventually want to use this telescope for photography, CCD imaging, or any other specialized purpose? 4) What is the nearest city/town to the area in which you plan on using the telescope? How far from this city/town do you intend to set up and use your new telescope? 5) If size and weight are important factors, what are your approximate limitations? I would point out that there are limits based on the person carrying the scope and parts, as well as being able to fit it into a car. 6) Do you want the telescope now; or are you willing to wait for the right telescope? 7) Are there any specific features or capabilities you think you would want or not want in your new telescope? What is there besides motorized tracking and GOTO? ![]() Actually, I'm not sure I could come up with very many that a beginner will be able to decide about. 8) Is there anything else that would be important for us to consider in order to direct you to the right telescope? 9) In which country do you stay? Some equipment manufacturers may not have distributors there. I'd ask a few more questions, such as: 10. Have you ever used a pair of binoculars before? Do you own a pair? 11. Have you ever used a telescope before? 12. Do you plan to observe primarily on your own, or with friends? [Tracking and GOTO take added importance if you're observing with friends.] 13. How many of the following objects can you find on your own? With a star map? a. Orion b. Big Dipper (or Southern Cross) c. Pleiades [M 45] d. Sirius e. The celestial pole f. Great Orion Nebula [M 42] g. Great Andromeda Galaxy [M 31] (or omega Centauri [NGC 5139]) h. Ring Nebula [M 57] (or Saturn Nebula [NGC 7009]) i. Whirlpool Galaxy [M 51] (or Southern Pinwheel [M 83]) j. Uranus k. Neptune l. Pluto 14. Which do you think you would enjoy more? a. The hunt for a celestial target b. The view once you find it Brian Tung The Astronomy Corner at http://astro.isi.edu/ Unofficial C5+ Home Page at http://astro.isi.edu/c5plus/ The PleiadAtlas Home Page at http://astro.isi.edu/pleiadatlas/ My Own Personal FAQ (SAA) at http://astro.isi.edu/reference/faq.txt |

Hi Brian,
Good points about beginners not being able to answer some of these questions. I remember quite vividly how I didn't know what I didn't know when I started. Fortunately, I read around in the newsgroups and found some good advice. Brian Tung wrote: 14. Which do you think you would enjoy more? a. The hunt for a celestial target b. The view once you find it This last is, to me, by far the most important question, one that I still have difficulty answering after 3 years in the hobby. --Ben |

Yes, good point:, I agree, and if you still have difficulty answering it,
probably it should not be in a questionnaire to beginners. Bill Meyers Ben Kolstad wrote: Hi Brian, Good points about beginners not being able to answer some of these questions.

Need to suggest price ranges here Would you be willing to spend more in order to get the performance you desire? Uninterpretable question. Leading question. Unclear referent: what performance you desire. (snip) 2) What would you like to be able to see? Respondent may not know. Need a list of possibilities. What specific details would you want to be able to see in those objects? See above. Presupposed knowledge respondent may not have, Again, what details are reasonable to expect? We should point out that lunar landers are unreasonable, but the rings of Saturn, and even some details in those rings, aren't. 3) Would you eventually want to use this telescope for photography, CCD imaging, or any other specialized purpose? 4) What is the nearest city/town to the area in which you plan on using the telescope? We don't need to know the name of the town. Need to zero in on the light pollution conditions How far from this city/town do you intend to set up and use your new telescope? Responses will be uninterpretable in terms of light pollution. And suppose respondent wants to set up in town? He or she may answer in feet or meters. 5) If size and weight are important factors, leading questions. what are your approximate limitations? Ambiguous. You may get some answers in terms of size and weight of respondent. Respondent I would point out that there are limits based on the person carrying the scope and parts, as well as being able to fit it into a car. 6) Do you want the telescope now; or are you willing to wait for the right telescope? Leading question. And double barreled. And The alternatives do not exclude each other. Non exhaustive and non-mutually exclusive alternatives are a big problem in poorly designed surveys. 7) Are there any specific features or capabilities you think you would want or not want in your new telescope? Vague question. Respondent may not know the alternatives. 8) Is there anything else that would be important for us to consider in order to direct you to the right telescope? 9) In which country do you stay? Some equipment manufacturers may not have distributors there. I'd ask a few more questions, such as: 10. Have you ever used a pair of binoculars before? Do you own a pair? Sexist question. :-) 11. Have you ever used a telescope before? For bird watching? Ambiguous. Awkward phrasing: before what? (Snip of a lot of good (mostly substantive) comments by Brian Tung throughout this post. I've confined myself to mostly methodological comments. Ciao, Bill Meyers |

As for me, I'm sticking with the three questions which have served well over
the years... 1. What's your budget? 2. Where will you use your telescope and how will you get it there? 3. What kind of observing would you like to do: lunar/planetary (Moon, Jupiter, etc.); deep-sky (star clusters and nebulae; or a little bit of both?

It's wonderful to see engineers and computer programmers design a
questionnaire. The results so far are a lot better than one might have predicted, probably because our posters know so much about the subject of the questionnaire This is a big help. Questionnaire design, though, is not only a common sense matter but also a fairly technical field in which one takes advantage of what has been learned from the mistakes and bitter experience of others in the past. Resort to a book on survey design would probably pay off here. I have seen many sad cases of questionnaires sent out to respondents at considerable cost of time, effort and money, that produced uninterpretable responses. This can be because of vagueness, or ambiguity, or double-barreled questions, or leading questions, or questions that presupposed some knowledge that the respondents didn't have, or questions that used language the respondents didn't understand, or where important questions that were not thought of in advance were unfortunately omitted. . Sometimes for example you want to tell the respondent what sort of answers you are looking for. Instead of asking, "Where will you use the telescope?" { some will answer, "near my house" or "outdoors" or "in Lafayette Indiana") You might ask instead: Will you be using the telescope (check as many as apply) in a large city where few stars can be seen with the naked eye in a suburb where you can see quite a few stars with the naked eye in a dark country sky (etc.) (These are just approximate suggestions.) And so forth. Bill Meyers |
