Telescope

The telescope is the light bucket that collects the light, focusing it to a point where we let form an image. We can adjust the amplification of the image by selection of lenses called ocular lens, or eyepieces.

Size matter - just accept it

Sadly, this is the case. The more light we can collect the brighter the image will be.

There are ways to compensate for a small size, this is true, but only to an extent. The more you use electronics to amplify the light the more you will have to deal with noise and other complications. 

There are many varieties of telescopes. Some versions are good for visual astronomy, some only for astrophotography. 

The ones I have are two of the main classes.

1. Refractor. Straight light patch with no obstructions
2. Reflector, light reflected on a back mirror and then off a secondary mirror to a focal point.
3. Catadioptic, a combination of the two above where a back mirror reflects the light to a secondary mirror, then back through a hole in the primary mirror to the focal point behind the telescope.

I have version 1 and 3
