When using a telescope, no matter how big, stars will look like stars. All things being equal, for visual astronomy, aperture is king, but beyond price, all things are not equal - and thus the telescope recommendation for someone who lives in Manhattan in a 3rd floor walkup apartment is different from someone who lives in rural Montana with a large garage and acres of no light around. That same 25mm eyepiece on an 8" Schmidt-Cassegrain telescope with a focal length of 2000mm will have a magnification power of 80x. Therefore, a 8" Newtonian reflector telescope with a 1200mm focal length and a 25mm eyepiece will have a magnification power of 48x. To determine that, you divide your scope's focal length by the millimeters of your eyepiece. The eyepiece (or ocular) is what determines your effective magnification. The primary purpose of a telescope is to gather light. Most newbies to astronomy think "a telescope makes far away things bigger." Yes, and no. The most important thing before getting into this hobby is setting your expectations. Are you yearning to marvel at the heavens? Have you been wanting a telescope but have no idea where to start? Are you feeling overwhelmed with the wealth of information and options out there? Well, here is a quick guide on some of the most commonly recommended telescopes here, what to expect when looking through your first telescope, and some frequently asked questions at the end.įor an in-depth eyepiece guide, check out this great post by u/Gregrox - A Beginner's Guide to Budget Eyepieces What to Expect when looking through a telescope Note this guide was originally written by /u/tripped144, but with global economic conditions, pricing has rapidly gone out of date, so consider this new guide a revision to the prior one written in 2020. r/telescopes aims to be a high quality sub where users can discuss all things telescopes and astronomy, but allowing such repetitive and low-effort posts will drastically lower the overall quality of the sub. Low-effort content such as those complaining about the weather (we get it, clouds are bad), simple questions that usually result in one line responses (these should be posted in our weekly discussion threads instead), general 'shitposting', memes, etc. Titles should be descriptive about what you're discussing/posting. Titles should not be 'clickbaity' nor self-deprecating - we're all here to learn so there is no point in calling yourself a 'noob' and/or putting yourself down. Concept art is not permitted, nor is content not relating to visual astronomy/telescopes. Images must be taken by you, with gear which you own - remote or professional services such as DSW or Hubble are not permitted. This enforces quality, encourages discussion, and benefits everyone. This includes your gear as well as any processing you did to the image. Images must have a top-level comment containing acquisition and processing details. Self promotion is only permitted to active members of the community. Not providing commentary, or posting content from a single source will be assumed to be attempts of driving traffic, which is not allowed here. This sub is a place for everyone to learn and help each other, and such behaviour only does bad things to everyone involved.ĭirect links should be accompanied by commentary as a top level comment, and should be a source of discussion. Non-civil behaviour such as insulting, flaming, etc, will not be tolerated. You can post used item ads here, but do post them on other communities or websites such as Cloudynights, Astromart, etc. There are other subs and communities for this. Links to petitions, surveys, crowdfunders, and other advertisements to sell your own products are prohibited here. Failure to read and posting "which telescope should I buy" will result in your post being removed and you being referred to this guide. If you're totally new to telescopes and astronomy, please read our Beginner's Quick Guide to choosing your first telescope which is sticky'd to the top of the subreddit. Posts are helpful for people with similar questions.)īefore posting, make sure your post follows the subreddit rules otherwise they may be removed. ( For more in-depth help, please use the subreddit. Anything that relates to amateur astronomy and its practice. Telescopes, eyepieces, events, marathons, charts, eyepieces, reviews, marathons, articles, etc.
