I am a beginner when it comes to telescopes and have been doing research online for a week with which one to buy. At the moment I’m interested in a pre-owned telescope. My priority is planets but also gaze to Andromeda if possible. I read that refractives are better for planets but I’m not finding them in my area maybe. Here are some that are available in my area:
- Celestron 114LCM (114 mm aperture, f/8.77 Newtonian) Computerised: I like that it has a motor that can automatically pin point to an object so will help me. But it’s a bit easy to locate the Moon, Jupiter and Saturn so do I even need it?
- Celestron Astromaster 130 EQ (114 mm aperture (not 130) f/8.7 Newtonian): it has better clarity I guess? But problem is, it is all manual and bulky. Means I have to adjust it every time I have to watch something new or to show to people. Also, it comes with heavy weight to might be difficult to carry around?
- Celestron Star Sense Explorer LT 127AZ (127 mm aperture, f/7.87 Newtonian)
I'm not asking a "shopping question" so don't tell me what to buy. But I would like some input about what criteria I can use to choose between these; are they all basically equivalent? Are there some types of features (in this class of telescope) that may be more important than others from the point of view of a beginning observer?
