Guidance for telescope purchase
Good morning,
I’m looking for some guidance. I’m sure this question has been asked hundreds of times before however I suspect the technology changes. Right off let me say thank you for your patience. I’d like to buy a telescope for my son’s family. They would use it both in Ottawa and at our cottage. I’d like something that will be relevant for the foreseeable future, can be moved from one location to another easily and provides very good visuals. Not knowing about telescopes I’m not sure what to ask, what I can tell you is my son always says when at the cottage we should get a telescope and take advantage of this. The more specific the suggestions the better. Thanks to you all, best, Leslie |
The Rasc is having a star party at the Carp library parking lot on Friday eve ,a great place to view a variety of scopes and ask questions . The North frontenac observing park is having a festival all weekend it would also be a good place to check out scopes? Dave?

Hi Leslie, Depends on your Budget (as this hobby can get very pricy). But here are some options to consider that I often recommend to people. ZWO Seetar S50 (it’s new and I’m hoping to review on soon but on paper it looks good) or Dwarf II Smart Telescopes, small portable and automated plus they kick out a basis image of the target you were observing. This is Electrically Assisted Astronomy that works off your mobile device. 10 or 12” Dobsonian Telescope, best bang for buck for light gathering power for visual observation.? Celestron C8 (Visual Use) or EdgeHD8 (Astrophotography) are bigger but can be setup etc by a single person. On a Tracking mount so they can follow targets in the night sky. There are a host of other options, as mentioned before StarParties are a great way to see the setups and consider the accessories required.

Good morning,A really good and affordable option these days is the StarSense Explorer lineup from Celestron. These are "push-to" mounts rather than computerized go-to but use a smartphone to find objects and visually align and place objects within the telescope's view. Eg. Rather clever, and easier to use that full-on computerized go-to mounts. Cheers -- Mark Lord |

Hi Leslie. You can borrow my SW150p free. It's on equatorial mount with tracking.? 613 858 0244 ---------- Forwarded message --------- From: Andrei Osmolovski <dalikidoo@...> Date: Wed, Sept 13, 2023, 11:53 Subject: Re: [OAFs] Guidance for telescope purchase To: <[email protected]> Hi Leslie.

Hi Leslie,
The most commonly given advice for a first scope it to get solid-tube dobsonian telescope of 6 or 8 inches aperture. These are completely manual telescopes, But the collect enough light (enough aperture or large enough diamter) show enough things in the sky to occupy one for a lifetime. Examples are: <> <> If you find these prices shocking, note that there generally isn't any telescope worth buying that is available for less than several hundred dollars. Good binoculars are a better buy in the less that "several hundred dollars" range. But not everyone likes the way a manual dobsonian telescope moves. So some will recommend computer controlled, or guided telescopes. An example is: <> which looks great on paper/screen. But I actually have one that scope. I can say with certainty the mount on that scope is very jiggly and it's nearly impossible to see anything with it at anything but the lowest power. Also the computer/phone control can point the scope to thousands of objects that the scope is too small (doesnt collect enough light) to show. The computer guided scopes Mark Lord wrote about are large enough to show a great many objects. But they are quite expensive (several thousand dollars) and are not beginner scopes. Even Mark, who is a very intelligent and tech-saavy guy went through about 3 telescopes before he settled on his current computer controlled Celestron. They can also be complex to use. So you will get a variety of opinions on the best starting telescopes. Instead I think the best advice is to attend a public star party where you can see a variety of telescopes and talk to the owners about them. That's why some people suggested you attend the public star party at the Carp Library/Deifenbunker this weekend. Too bad you can't attend. The next best advice is to join the Ottawa Centre of the Royal Astronomical Society. Not just becuase there are lots of helpful and experience people there, but because that club has about a dozen different telescopes that they rent to their members for about $10 a month. It's a telescope lending library. That is definitly the cheapest way to try several different kinds of scopes at your home at your lesure. see: <> A final note: resist the urge to buy anything labeled "telescope" at wal-mart or any department store. Those are toys. The Ottawa RASC club held several "scope clinics" where we invited members of the public to bring their telescopes so we could help them tune them up and use them. A great many people brought "department store" or "bought in a hurry for Christmas" scopes that were largely unusable. Or some were so complicated that they were never unboxed before. Some clues that you should not buy a telescope in a retail store are: - the box has hubble pictures on it - the box lists magnifications (any telescope can be made to have any magnifcaiton by changing eyepieces. The best views are usually at the lowest magnification) - the box is under a sign that says "all sales final" :) - you read the instructions and you don't know what the words mean. Telscopes can be expensive. You may be advised that you can save a lot of money buying used (say on Kijii). That is true. But it takes a lot of experience to distinguish an unuable "deparment store" telescope from a good buy. I suggest you avoid buying used unless you have an experienced telescope-user check out the scope before you buy. If you're going to buy a new scope, buy from experienced and dedicated telescope stores. Two example are Astronomy Plus and La Maison de l'Astronomie which are both in Montreal (sadly the telescope store in Ottawa went out of business) or from store with excellent return policies. Surprisingly, Costco sell telescopes by mail order with a very good return policy. But don't be surprised if you return 2 or 3 of them before you get something that actually works for you. The best and briefest advice is "try it before you buy it". Which is actually hard to do unless you have access to a telescope-lending library like at the Ottawa RASC. best of luck. attilla danko, , danko@..., attilladanko@...

I second Adam's vote for binos to start. (I started with a 60 mm Tasco refractor, but let's call that half a binocular.)
With a pair of binoculars, they can spend many a pleasurable evening on a garden chair with maps learning the sky. There are plenty of sites online that list cool things you can actually see with binoculars and a little practice, like star clusters, galaxies and the odd nebula.? ?After a couple of months of using binoculars, they'll know the skies, they'll know how to find stuff, they'll have their expectations set, and their eyes will have learned how to see details at low light levels. And they'll know one more important thing: do they really love looking at the night sky--even when it's nasty cold or when the mosquitoes are out in force?
?
If you were to start them with a larger scope, they might have the same experience as people I sometimes meet at public observing sites.? They've got a new scope, but they're frustrated, because they don't know their skies, and they can't find anything to look at besides the moon and some of the brighter planets.? A computerized Go-To scope--one that can find things on its own--will alleviate some of this frustration, but they cost a lot more than $300.? Besides, I have a friend who has what he sometimes calls a "Go-Near" scope. "Go-Near" because, when it's not aligned properly, it can't find anything, even though I still can. Maybe I'm old fashioned, but I think it's best to learn the sky first, and then use the machines to help you later. (I also walked two miles to school through waist-deep snow uphill both ways when I was a kid.)Now, some would say that a pair of binoculars is not really a telescope.? However, for $300, you can get a good pair--a pair that will last a lifetime.? They'll need them for that long, too, because if they later decide to buy a scope, they'll still be using the binos to reconoiter the skies when they're seeking difficult quarry.
?
Not only that, they may find that their lifestyle does not readily admit a "family" telescope. My wife >hates< telescopes. They take up too much space and too much of my time, she says.? Their first telescope may be like my third--a Short-Tube 80mm f/5 refractor not much bigger than a pair of binoculars that I hide amongst my wife's shoes.? Binoculars (like my ST 80, but not including its tripod) will be easy to take back and forth between the cottage and home because binos don't take much space.
Finally, let's talk about the worst case scenario: suppose they decide after learning the sky that astronomy is not for them. I think they'll still find the binoculars useful -- particularly at the cottage for looking at birds and other things (or in the city for spying on neighbours, not that I've ever been known to do that obsessively).? But, if you're set on a scope, you can't beat a basic 6" or 8" Dob.? |
开云体育Wow, what a wonderful, knowledgeable, supportive community. ?Thank you! ?Lots to take in and understand. I’ll take some time to go through in detail all of this information before I make any decision. Again, thank you all, I really appreciate your guidance.?Best, Leslie On Sep 13, 2023, at 1:13 PM, yeldahtron <keith_hadley@...> wrote:
