Detailed Star Atlas'

Recommended Posts

I was wondering if anyone knew of a star atlas that had very detailed information on less visible stars contained in charts.  I have found that a great many stars simply do not have any identification or markings for them but are simple dots surrounding other "more important" stars.  Does anyone know of very detailed star atlas' (perhaps ones used by professional astronomers) that will give me more information on these missing objects?

Best,

You may be better served by using one of the free planetarium programs such as Cartes du Ciel or Stellarium. 

I use a commercial one called SkyMap (there are plenty of others) that lets me adjust the field of view and control which stars are shown by magnitude.  For each one, LOTS of information is available.  Here is an example from a star chosen at random (it is displayed much more neatly in the program)

Information about TYC 665-229-1 Summary Visual magnitude: 7.45 Spectral type: M...

Hipparcos Catalog Data

Hipparcos Catalogue (ESA SP-1200, 1997).

Hipparcos Identifier/Proximity Flag Catalog number: HIP 19003 Proximity flag: None Descriptor V magnitude: 7.45 Variability: This star entry is variable at a level of 0.06 to 0.6 mag Source of V mag: Median Hipparcos magnitude (Hp), combined with information on the colour index (either V-I or Bt-Vt), in combination with the luminosity class. Main Mission Astrometric Data Equatorial coordinates (epoch J2000.0, ICRS) Right Ascension: 04h 04m 18.7619s Declination: +12° 30' 26.800" Standard errors of the equatorial coordinates (epoch J1991.25) RA: 0.00090 arcsec Dec: 0.00066 arcsec Parallax information Trigonometric parallax: 0.00360 arcsec Standard error of the parallax: 0.00097 arcsec Proper motion components (epoch J1991.25, ICRS) RA: +0.06066 arcsec/yr Dec: -0.01795 arcsec/yr Standard error in RA: 0.00113 arcsec Standard error in Dec: 0.00081 arcsec Miscellaneous astrometric information Percentage of data rejected (F1): 0% Goodness-of-fit parameter (F2): -0.79 Tycho Photometry and Colour Indices Bt magnitude: 9.938 Standard error in Bt: 0.038 Vt magnitude: 7.672 Standard error in Vt: 0.013 Johnson B-V colour index: 1.913 Standard error: 0.033 Source of B-V value: Determined from the transformed Tycho Bt-Vt data. Cousins' V-I colour index: 2.83 Standard error: 0.05 Source of V-I value: Method O Main Mission Photometry Median magnitude, Hp: 7.4014 Standard error in median magnitude: 0.0046 mag Scatter of Hp observations: 0.020 mag Number of Hp observations: 42 Main Mission Variability Observed magnitude at maximum and minimum luminosities Mag at max, Hp: 7.36 (5th percentile) Mag at min, Hp: 7.42 (95th percentile) Type of variability: Unsolved variable. Entries are classified as "unsolved" if they do not fall into the other variability categories - this class also includes irregular or semi-irregular variables, and possible variables with amplitudes >=0.03 mag. Comments: Variability data for this star, such as periods, amplitudes, reference epochs, etc, compiled from the Hipparcos Hp data, along with associated ground-based data, are given in the table of "unsolved" variables in the Hipparcos Variability Annex. Multiplicity Data Number of components: 1 Reliability of the solution: Suspected non-single, ie possible double or multiple, although no significant or convincing non-single star solution was found. Miscellaneous Comment: This is a "survey" star. HD identifier: HD 25605 DM identifier: BD +12 0547 V-I colour index: 3.08 mag Spectral type: M... Source of spectral type: SIMBAD

I have one of these

http://www.amazon.com/Millennium-Star-Atlas-Comprising-Catalogues/dp/1931559279

Which goes down to magnitude 11 and has masses of detail and some objects that Stellarium doesn't (eg Shapley1 planetary). But to be honest, having downloaded the extra stars for Stellarium so it goes pretty much as deep, the paper atlas is more or less redundant. The electronic one has so many cool features such as image flip for viewing in diagonals and you can zoom to any field of view with no map edges. Running on a tablet or smartphone next to the telescope, I find it much better than paper. One of my few concessions to the 21st century :D

All the best

Very interesting.  I will check out SkyMap and see what I can observe.  So far I would like to thank everyone from SGL for being so helpful with their advice and time.  I really have gotten back into astronomy in a big way and most of it is thanks you, the wonderful people of this forum.

Best,

Jackstay

I use the Deep-Sky Hunter Star Atlas ( http://www.deepskywatch.com/deep-sky-hunter-atlas.html ). You can download it for free and is accurate for my use.

As the website reports " 'Deep Sky hunter' is a printable deep sky atlas, designed for serious deep sky observers. It features stars down to 10.2m and DSO down to 14.0m."

Otherwise, I guess you need a software. Stellarium is open source and does a good job and if you download the "extra stars", you can see stars down to 18m, I think.

Carte du Ciel also offers a nice (deep) view of the sky and its beauties.
