Swoop1 Posted January 4, 2017 Share Posted January 4, 2017 OK gang, so after listening to your advice on a previous topic (basically spend a bit more if I can afford it) I have upped the budget a bit from around £150- £175 to about £200 (can't afford any more). At this sort of price point, what are the merits of a refractor or a reflector? My goals are studying the moon, looking at the planets and hunting for galaxies etc. I would like to image eventually, not now sure if this would be by way of DSLR or a webcam. Back yard set up with occasional trips to rural common land to escape the light pollution. Thanks folks. Link to comment Share on other sites More sharing options...
MattJenko Posted January 4, 2017 Share Posted January 4, 2017 I would go manual reflector and worry about imaging later. The quality of the reflector is going to be better (not to mention bigger) than an equivalent cost refractor/tripod/mount. A decent sized Dobsonian at this price point every time for me.

LukeSkywatcher Posted January 4, 2017 Share Posted January 4, 2017 On that budget you can have a nice big aperture reflector. Refractors are/can be expensive, and for the same budget you would get a lot less aperture. Link to comment Share on other sites More sharing options...
triton1 Posted January 4, 2017 Share Posted January 4, 2017 It's a no brainer reflector on a dob base. Link to comment Share on other sites More sharing options...
johnfosteruk Posted January 4, 2017 Share Posted January 4, 2017 I don't know if you can go the extra £9 or not but if you can https://www.firstlightoptics.com/dobsonians/skywatcher-skyliner-150p-dobsonian.html is the kiddie you're looking for. Easy to use mount on a dob and 6 inches of lovely reflector aperture. You'll get good sharp comfortable views. 3 Link to comment Share on other sites More sharing options...
Moonshane Posted January 4, 2017 Share Posted January 4, 2017 Seek out a used 150mm f5 skywatcher Newtonian and AZ4 You cannot go wrong and would have some left for sundries 2 Link to comment Share on other sites More sharing options...
Mr Spock Posted January 4, 2017 Share Posted January 4, 2017 Yep, for that budget a Dob is the most scope for your money. 1 Link to comment Share on other sites More sharing options...
brantuk Posted January 4, 2017 Share Posted January 4, 2017 (edited) Useful refractors start around £350 for an appo doublet of about 70mm to 80mm and that is "scope only" I.e. no mount. Achros are a little cheaper but you will get spherical abberation and fringing. So really it's academic that a reflector would be the choice for your budget. Get the largest aperture you can and the most appropriate mounting - for me that would either be a brand new 150P on a dobsonian base - or a second hand 200P Dobsonian. If you can find a good second hand 8" dob you wouldn't regret it. (Check SGL classifieds or UK Astro buy/sell - probably the best two places to look).

laudropb Posted January 4, 2017 Share Posted January 4, 2017 I think that the message is clear. For your budget a Dob will give the best value for money. 2 Link to comment Share on other sites More sharing options...

ronin Posted January 4, 2017 Share Posted January 4, 2017 Ignoring everyone, Which do you actually want? Which one in your mind do you see yourself looking through. A post some time back coverd this and said to get the one you want as there is a greater chance of you using it the most. 1 Link to comment Share on other sites More sharing options...

Cosmic Geoff Posted January 5, 2017 Share Posted January 5, 2017 Tricky choices - from experience I'd say that it's a good idea to have a general purpose scope. Your budget will restrict you to something fairly simple - or a lucky second-hand purchase. For the Moon and planets you can get away with a scope of modest size on a fairly basic mounting. At high resolutions the blurring effect of the atmosphere dominates which means that the actual performance of larger apertures compared with their theoretical performance is usually disappointing (unless you are on a mountain top.) I've noted that some experienced planetary observers recommend an expensive ED or APO refractor of modest aperture. The rest of us just use what we've got. Unless you become a planet specialist, looking at them will not take up much of your observing time, so it would be desirable to have a telescope that works for deep-space objects as well. For galaxies, star clusters, nebulae and globular clusters, large aperture is a decided advantage. It is also a decided advantage to have GoTo, otherwise you may suffer the frustration of knowing that your telescope will show you many fine objects if you could only find the damn things. On the planetary front, GoTo is also a massive time-saver for looking at Uranus and Neptune which can be tricky to locate otherwise, given that they are faint and look star-like at low magnification. With GoTo you can also locate the brighter planets in daytime. Reflector or refractor? Refractors don't have a central obstruction and should out-perform a reflector of the same aperture. But they become very expensive as the size goes up. Your choice. Focal ratio - a feature rather than a problem. It becomes an issue if you need an eyepiece to give high magnification on a f5 scope, or want to view one of the large deep-sky objects (rather few in number) with a f12 scope and find it won't fit in the LP eyepiece field. Mountings - some amateurs clearly prefer the simplicity (and low cost) of the basic unpowered alt-azimuth mountings, while others would not be without their powered equatorial mounts or their GoTo. Your choice. Link to comment Share on other sites More sharing options...
Swoop1 Posted January 5, 2017 Author Share Posted January 5, 2017 Thanks for the input CG- much appreciated. I have a sneaking suspicion I should have grabbed the bull by the horns and taken the plunge last night on this- http://www.ebay.co.uk/itm/201770474750?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT Came to look at it this morning and BOOM! beaten to it I am going to attend my local societies' Telescope Night tonight- who knows, someone may be looking to offload something.

MattJenko Posted January 5, 2017 Share Posted January 5, 2017 I wouldn't worry about missing out on that auction. Starting off with a manual EQ mount and a Newtonian isn't the most intuitive or comfortable of experiences. Link to comment Share on other sites More sharing options...

Swoop1 Posted January 6, 2017 Author Share Posted January 6, 2017 Just committed to a return Sky-watcher Explorer 150P EQ3-2 Newtonian. Can't wait for it to arrive so I can get searching the skies Thanks for all you help and advice. 1 Link to comment Share on other sites More sharing options...
