These are the kinds of considerations you will learn toĪpply to your future optical equipment planning. You'll read about needingĪ big Newtonian for Deep Sky objects, and the planets are best seen through a large, long focal ratio refractor or a Maksutov-Cassegrain. Know! General viewing / Planets / Deep Sky / Comets.ĭifferent areas of astronomy require different optical equipment. Learn more about the things you're looking at you'll get an idea of the direction you would like to go and decide what your favourite types of astronomical object are. Recommended to get either a refractor or a Newtonian, dependendent on your area of interest or preference. There is also complete information covering most other types of telescope that you may have come across, for those that are interested. Please read on to get information on the size of telescope you need to see the things you want to see. The case because they are the simplest and therefore have the largest aperture for your money available - So you can get into the right SIZE of telescope with the minimum outlay. The reason I recommend only the refractor and the Newtonian telescope types is that these are the two best suited to the beginner. What you really want to avoid is spherical mirrors and Catadioptric Newtonians - see later. Parabolic mirrors are sometimes, ratherĬonfusingly, called 'Aspherical' mirrors. Parabolic 130mm (Search "130P" and see the Newtonian Reflector section below). The smallest Newtonian I recommend for a proper start into astronomy is a Mirror (see 'Parabolisation' section later) and would not produce images as good as an 80mm achromatic refractor. You will need something slightly larger to see what you will read about and want to see.Īlthough, technically, the 120mm Newtonian should be at least equivalent to an 80mm refractor (See 'Resolution' section later) this model has a spherically figured These two (left) are impressive looking instruments, with their equatorial mountings and slow motion controls, but they are too small to be of any I will generally refer to them as Newtonian and Refractor, to save confusion between reflector and refractor. The two types of telescope I am going to recommend are: 'Newtonian Reflector' and 'Astronomical Refractor'. In this guide: 20+ Photographs / 30+ Illustrations / 2 To the best of my ability with many pictorial examples why this is the case. I recommend the beginner starts by using one of TWO types of telescope and I'll give you a guide onĬonsideration: Especially for the beginner. Qualifications in astronomy, having been a director of an astronomical company, and with over forty years experience in observational astronomy, I hope you will trust my informed guidance in this Guide you to the 'trainers section' (A good durable shoe that is suitable for many, many different activities!)Īllow me to guide you towards your first 'scope with an explanation of the considerations you need to make while choosing. You wouldn't wear high heel stilettos to a tennis match - Or use an f15 refractor for Deep Sky Objects. Others, the ones I will guide you to, are suitable for many applications. There are many different telescope types and the reason for this is different subjects require different optical perameters.Ĭhoosing the right one for you is a bit like choosing shoes! There are many different types of shoe, and some are suitable only for certain activities. Telescope that you will be able to keep using for many years without great expense.Īny telescope is better than no telescope at all, but very small telescopes have very limitedĪpplications in astronomy and will soon have you wanting to see more. My advice will save you throwing away money and will get you a If you buy yourself the wrong one, you may end up giving up on astronomy because your expectations have been let down. S ooner or later, if you're interested in astronomy, you'll decide you want a
