When it comes to different types of equipment used in astronomy, it's all about lenses. Achromat lenses used to be really popular among astronomy enthusiasts, but the biggest problem with them is a significant chromatic aberration. These lenses bring two colors into focus on the same plane. When you look at the bright objects, you get a purple halo around them. That's why it is better to use apochromat lenses, that bring three colors into focus.
ED glasses, or extra-low dispersion glasses, reduce this unappealing glare, or residual color significantly. This means that if you use one good apochromatic telescope, it will give you much better observing experience, with sharper images. This is especially important for anyone primarily interested in observing planets and bright stars or photographing them.
Visiting some astronomy club in your neighborhood might be a good idea for anyone who doesn't have much experience with this. Taking a good look first might make you realize what you will actually get with different types of telescopes. Although good quality equipment definitely costs more, it's something you should invest in, because it gives you far better observing experience.
Buying cheap is never a good decision. You will most probably find all types of equipment in any larger supermarket, sometimes at more than affordable prices. But, you have to be aware of the fact that these things are only toys. You don't want to waste your money on this. Find someone who knows a little something about astronomy and get a few pieces of advice first, just in case.
APO 4 "(102mm) refractors are very popular despite the price, because this diameter already allows you to observe darker objects and to have a more detailed look at the planets, and are still portable enough. Image quality is unbeatable. APO refractors are the best quality astrographs, but they cost considerably more than "ordinary" visual APO refractors. In any case, APO 4 '' or larger is a good choice.
Smaller compact models have numerous advantages. For example, larger models might be more complicated to assemble. This probably won't make a difference for people who plan to keep their equipment assembled in their home, but you will probably want to take a trip somewhere every once in a while, to get a better view to some events, and, in this case, assembling your equipment might be an issue.
Achromatic models are a much cheaper solution, and mentioned glare effect may be reduced on larger f-numbers. This might be a good solution for people whose children suddenly show their interest in astronomy, and this interest might not last for long. In this case, it might be a good idea to take small steps first.
In any case, it is up to you. Depends on your interests, the amount of money you are ready to spend and so many other factors. In case you don't have any experience in this, find someone who has, or some astronomy club in your area. Find out more about this field and about different types of equipment, before making your final decision.
