What are the advantages of a refracting telescope?
- Superior revolving power per inch of aperture.
- Superior performance in inferior conditions – image steadier.
- Not reflections or interruption of light path.
- Near permanent optical alignment – minimum maintanance.
- Long focal ratios can mean use of longer focus, simplier, eyepieces.

What are the pros and cons of reflecting telescopes?
|Large mirror = better light collecting capacity No chromatic aberrations (colored fringes around stars) Relatively low cost||Optical quality often disappointing Collimation and mirrors cleaning processes Open tube = high vulnerability to dust, humidity..etc Bulky and heavy|
How do reflector telescopes produce images?
In a reflector, the objective (a mirror as opposed to a lens) is located at the back of the telescope. … This secondary mirror brings light to a focus from point 1 to point 2 on your screen. Just as before, the eyepiece takes over thereafter to help magnify the image for your eyes to appreciate.
