Discussion Overview

The discussion revolves around locating a bright star catalogue, specifically one referred to as "visyar," and the challenges associated with using star maps for identifying fainter stars. Participants share resources and advice related to star-hopping techniques and equipment issues encountered during stargazing.

Discussion Character

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

Main Points Raised

  • One participant seeks the correct spelling and link for a bright star catalogue, initially unsure of the name.
  • Another participant provides the link to the Vizier database, suggesting it may be the resource sought.
  • A participant expresses gratitude for the link and discusses the star-hopping method for identifying fainter stars.
  • Concerns are raised about the suitability of the Vizier site for learning star-hopping, with a recommendation for a star-charting program instead.
  • Frustration is expressed regarding difficulties in locating ~10 V. magnitude stars due to telescope pointing inaccuracies and issues with refocusing when switching between eyepiece and camera.
  • A suggestion of using a flip mirror is mentioned, along with uncertainty about its effectiveness, prompting a request for verification of this advice.

Areas of Agreement / Disagreement

Participants generally agree on the usefulness of the Vizier database but express differing opinions on its appropriateness for learning star-hopping techniques. The discussion regarding the flip mirror remains unresolved, with varying levels of expertise among participants.

Contextual Notes

Limitations include the dependence on personal experiences and informal advice from acquaintances, which may not reflect expert consensus on equipment and techniques.

Who May Find This Useful

Astronomy enthusiasts, particularly those interested in stargazing techniques and resources for identifying stars using telescopes and star maps.

I'm wanting to look at a bright star catalogue and I've been told to use something pronounced as visy-ar. I've typed 'visear', 'visiar' and some other spellings in google and can't find the site. Does anyone know the link at all and how the name of this database is actually spelled?

Thank You!

That is indeed it. Now I can just hope that this 'star-hopping' method using nearby bright stars will help me in identifying fainter stars using star maps.

Really appreciate your help
 
Hi Soilwork,
I wouldn't recommend a site like vizier for learning star-hopping. It's aimed more towards the professionals. For your purpose, a star-charting program should do fine. I can say only good things about http://www.stargazing.net/astropc" .

Thanks for suggesting that. I will give it a go and see if it works.

As of now though I'm having huge trouble finding ~10 V. magnitude stars using the star maps and because the telescope isn't reliable in pointing absolutely accurately, the stars never appear in the FOV of the camera. Another problem is the re-focusing when switching between eyepiece and camera, which seems to knock the stars out of the FOV of the camera.

It's getting quite frustrating and I'd appreciate if anyone had any tips.
I was told that a flip mirror could be used, but at the same time I was told that it isn't that great. I mean the people I know aren't particularly experts, but they are getting me involved in observing and so all my information comes from conversations with them. So if any of you could verify the flip mirror suggestion I'd be greatful too.
