Though simple in design, the refractor telescope has its own set of drawbacks. For the refractor telescope, caution should be exercised when selecting a less expensive model. According to “Stargazing With A Telescope” by Robin Scagell, you should start with a good quality 60mm lens when considering a refractor telescope. The disadvantages of a refractor telescope include:
1. This type of telescope costs more than its Newtonian and catadioptric counterpart when you compare models of the same aperture size.
2. The refractor telescope can be ill suited for viewing faint astronomical bodies due to the design of the telescope and aperture.
3. Though the images come across clearly, you may get unwanted color fringes around the objects in view.
4. The lower end models of the refractor telescope tend to lack enough quality for decent astronomy viewing.
first! thanks it helped me :D
thanks man! you totally just helped me on my science project!
i think this answer is good but you should try to step it down.
aha, this is very intersreting boh
ithis helps a little but not much
thank you
Indeed said, the length of the telescope,specially when viewing high on horizon make you bend so much causing pain in waist. After all refractor,s are very good.
