Discussion Overview

The discussion revolves around the suitability of 60-80 mm refracting telescopes for beginners in amateur astronomy. Participants explore the capabilities of these telescopes, specifically regarding their ability to observe celestial objects like Saturn and the potential for using binoculars as an alternative starting point.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant inquires about the visibility of Saturn and its moon Titan through an 80 mm refracting telescope under good atmospheric conditions.
  • Another participant suggests that a 70 mm refractor with a focal length greater than 700 mm is the minimum recommended size, stating that 60 mm scopes have poor mounts that may frustrate users.
  • It is proposed that an 80 mm refractor is a significant upgrade in quality, both in optics and mount, and can provide clear views of Saturn, although details may be limited.
  • A comparison is made between the refractor telescopes and a 6" Dobsonian telescope, which is suggested as a better option for similar pricing due to superior image quality.
  • One participant expresses a shift in interest towards starting with binoculars instead of a telescope, sharing a specific model for feedback.
  • Another participant agrees that binoculars are a good starting point, noting the need for a tripod to stabilize the 15x magnification and highlighting the advantages of binoculars for beginners.

Areas of Agreement / Disagreement

Participants express differing opinions on the best starting equipment for amateur astronomy, with some advocating for refracting telescopes while others prefer binoculars. There is no consensus on the ideal choice, as preferences and recommendations vary.

Contextual Notes

Some limitations include the dependence on atmospheric conditions for visibility and the quality of the mounts and optics in the telescopes discussed. The discussion does not resolve the effectiveness of the suggested equipment.

I posed this question in a thread in the GD forum because I had not yet seen this thread and, wretched creature that I am, I neglected the search tool. Anyway, regarding beginner telescopes, I thought some of you might be able to provide some insight. I read that a good beginner range is a 60-80 mm refracting telescope. How far and how clearly would an 80 mm be able to see? For example, how clearly would I be able to see Saturn (assuming good atmospheric conditions) with an 80 mm? Would I be able to see Titan as well? I define the word "novice" when it comes to telescopes and any help would be much appreciated.

The smallest refractor you should get is a 70mm with a focal length greater than 700mm, IMO. The 60mm scopes available nowadays have truly horrible mounts and will really frustrate you. The 80mm scopes are a real step up in quality both in optics and the mount, so that is the one I would choose in the range you suggest. A decent 80 to 90mm achromatic refractor telescope (Celestron, Meade, Orion, Skywatcher, Explore Scientific, AstroMaster, etc...) will cost you from $150 to $500 depending on quality and the mount you choose. Those scopes will let you see Saturn fairly clearly but it (Saturn) will be small and you might not be able to make out some fine details. These scopes come with low cost diagonals and eyepieces which can affect the quality of the image you see.

For nearly the same money (~$300), you could get a much higher quality 6" dob that would give you much better images, IMO.

Thanks! I think you started typing your answer before I temporarily took my question down to search the thread. I got my answer, but I re-posted my question anyway to avoid confusion. My sights are currently set on the Orion XT8. There is a payment plan available for $120/month that seems like a really good deal.

Again, thanks for for your help.

I've reconsidered and I think I'm going to go with binoculars to start my amateur astronomy journey. How do these look?

Those are good, but you're going to need a tripod to hold them, as 15x magnification is practically impossible to hold steady with just your hands. Binoculars are good for starters, as they generally have a wide field of view and don't require collimation or adjustments.

The tripod shouldn't be a problem.
