I don't know buying which telecope for myself. Many beginners have this tough time when he step into astronomy.
Selecting and buying the right telescope really boils on on your budget, what you plan on spending the most time viewing, and where you will using your telescope most at. With that said, below are some guidelines.
Telescope Rules of Thumb
First telescope and on a budget? Choose a Dobsonian.
Interested mostly in viewing the moon and planets? Buy a refractor.
Interested in viewing galaxies, nebula, and star clusters? Buy the biggest reflector you can afford - this will be a Truss Tube Dobsonian.
Concerned about portability and weight but want a good all-around telescope? Buy a Cassegrain.
Want absolute quality and money is no object? Buy an apochromatic refractor.
Serious about astrophotography? Buy an apochromatic refractor or astrograph reflector.
Do's for Buying Telescopes
As a first telescope, a 6" or 8" Dobsonian reflector offers great bang for the buck. On the refractor side, an 80mm on a stable mount is also an OK alternative first telescope.
Get an oversized/overrated mount - telescope mounts MUST be sturdy.
Stick with 1.25" size eyepieces at a minimum, stay away from 0.965" designs.
Get a size and weight that you don't mind setting up or lugging around to remote sites.
Select 2 (or 3) quality eyepieces and a Barlow lens. Lower-cost good-quality eyepieces are Plossl eyepieces. The Svbony filter kit is also a great deal.
Get a guide scope.
Don'ts for Buying Telescopes
Don't buy a telescope from a department store, nature-science store or toy store. These are totally unsuited for astronomy and will end up unused or in the trash.
Stay away from 0.965 size eyepieces -1.25" eyepieces are a minimum.
Avoid getting so large and heavy of a telescope that you don't want to use or transport it around.
Small tips hope could help you choose a right telescope for yourself. if you really could not make a final decision, then choose Svbony SV48 for viewing the planets, never be wrong. any further questions, please send email to firstname.lastname@example.org.
