>>13986822I have one but it's in hungarian, so unless you are a hunbro, the best i can do is give you some advice. But I'm no experteither, i have only been doing this or a short while.
Basically the most important thing is the aperture. That determines light gatehring capacity, which translates to resolution. If you are looking at telescopes you'll get a number like 80/600 (this is in milimeters, yours may be in inches or thumbs or hamburgers). The fiirst is aperture sizte, the secontd is focus leangth. The bigger the first number, the better. The second number is important when choseing your ocular. Magnification is second number devided by oculars size. So my 80/600 telescope with a 20mm ocular gices 600 devided by 20 so 30x magnification. But that can only magnify the resolution the objective gives you. So a 200/600 (i don't think these exist) would give you the same magnification with higher resolution.
The other important thing is the type of objective. So objectives have two main problems. Spheric aberration and chromatic aberration. Sheric means the edges will be distorted, chromatic means the colours will be in focus at different points. Cheap lenses will not be corrected for either, a really expensive one called an apochromatic will be corrected for all of the above. This is only important if you are searious about astro photography, and it is really expensive.
Last thing to cosider is mount type. Altazimutal goes right left up down, equatorial follows declination and rectascension. So it's less intuitive, but it is better for photography. You point it at a planet, or the moon, set a motor earth rotation speed and done. Your telescope will follow that little fucker so you can take long exposure.
There are also all kinds of accesories, foil or glass to go nfront of you objective to watch the sun without anting yourself, finderscope, plar alignement scope, barlow for easy magnification, zenith so you don't have to crouch under your telescope, motor...
