second one is the Sagittarius star cloud. I don't know how to add the last one))

well, it's a rather large array of stars, isn't it? When you'll add constellations, I'm assuming here you'll create some sort of "super optical star cluster", you could use the same system to assemble those stars, at least their borders, with a "constellation-like" object and name it M 24. or something like that :)

moreover, you'll have the ability to create boundaries for an "Orion arm" or "Terran galactic empire", visible and selectable from outside the galaxy...

I added M 24 as a star cluster with new special type "Part" (part of the galaxy) and no procedural stars. It could be displayed in GUI as "Star cloud M 24".

Cor Caroli - alfa CVn is a binary, not yet in the catalog. I've made a patch with data I've found, to be placed in data/catalogs, it will replace the Hipparcos entry.

In the 'Stars-bin.sc' file are three stars that have the parameter 'RadiusSol', instead of 'RadSol' as the correct parameter is now.

'Albireo Ab', 'Albireo Ac' and 'Albireo B'

'RadiusSol' gives a wrong size for a star.

I've made a patch for it. Put in 'data\catalogs\planets'

(90) Antiope is now binary instead of a single one.

Here's why I decided to make both binary asteroids just be classified as "Asteroid"; a dwarf moon would reveal it position amongst single asteroids. If they don't have a barycenter, the would-be moon would be scorched. A dwarf moon wouldn't make sense since the dwarf moon would overlap with the main body.

HD 45688 it's a star with a brown dwarf as companion. in Catalogs0974.pak there's an entry under stars/browndwarfs-bin.sc but there's no entry in /planets for this barycenter, and it returns wrong data.
The missing code in /planets/browndwarfs-bin.sc should be:
Code
Star "HD 46588 A/23H. Cam A"
{
    ParentBody "HD 46588"
    Class      "F7 V"
    MassSol  1.08
    AbsMagn  4.17
    Radius  835610
    Orbit
    {
  Period          48850.0446    //Generic
  SemiMajorAxis   79.44056
  ArgOfPericenter 0
  MeanAnomaly     0
    }
}

Star "HD 46588 B/23H. Cam B"
{
    ParentBody "HD 46588"
    DiscDate   "2011"
    Class      "L9"
    MassSol    0.064
    AppMagnJ    16.26
    AppMagnH    15.08
    AppMagnKs    14.60
    Orbit
    {
  Period          48850.0446  //Generic
  SemiMajorAxis   1340.55944   //    1420 AU from the main
  ArgOfPericenter 180
  MeanAnomaly     0
    }
}


The attached file can be placed in data/catalogs/planets/ to correct the issue.

The strange case of HD 46588

Okay, Mosfet was faster, anyway, here's my version. dry

Code
// HIP 32439/HD 46588 patch
// HD46588patch.sc
// Source = http://adsabs.harvard.edu/abs/2011ApJ...739...81L
// Source2 = https://es.wikipedia.org/wiki/23_H._Camelopardalis

Star "HIP 32439 A/HD 46588 A"
{
    ParentBody  "HD 46588"
    Class       "F7V"           // (Source)
    MassSol     1.08            // (Source2)
    
    Lum         1.8             // (Source2)
    //AppMagn     5.43750008
    
    Teff       6165             // (Source2)
    
    FeH         -0.25           // (Source2)
    
    Orbit
    {
        SemiMajorAxis   74.559029
        Eccentricity    0
        Inclination     0
        AscendingNode   0
        MeanAnomaly     0
        ArgOfPericenter 0
        RefPlane        "Ecliptic"
    }
}

Star "HIP 32439 B/HD 46588 B"
{
    ParentBody "HD 46588"
    Class       "L9"            // (Source)
    MassSol     0.064           // (Source)
    
    Orbit
    {
        SemiMajorAxis   1345.440971    // Separation 1420 (Source)
        Eccentricity    0
        Inclination     0
        AscendingNode   0
        MeanAnomaly     0
        ArgOfPericenter 180
        RefPlane        "Ecliptic"
    }
}


Also the position is incorrect. I have not corrected this. This would require the file 'BrownDwarfs-bin.sc' be changed.

The star CK Carinae has a radius of merely 1060 km. It should be 1060, but solar radii instead. I hope the new one is correct.

Code
// new radius
Star    "CK Car/HD 90382/SAO 238038"
{
                    RA       10 24 25.3580
         Dec     -60 11 29.039
         Dist     2176.8234
         Class   "M3 Ia"
         AppMagn  7.59
         Radius   737760000
         Teff     3550
}

The star Kepler-442 (KOI-4742) is too bright, making the planet a burning hell instead of an beautiful Earth-like planet. cry

Here, several stars have problems: 1. S. Dor, current lum; 268 000, actual lum; 910 000 - 2. ETA Car, current lum; 14 249, actual lum; 5 000 000 - 3. Rigel, current lum; 51 711, actual lum; 120 000 - 4. Betelgeuze, current lum; 9 446, actual lum; 90 000... and many many many many more (almost all) luminous stars are much dimmer than reality. Why, i ask??

This has been answered multiple times. Change luminosity of that stars to real values and look on the sky from Solar System. Come constellations got distorted, right? This is because SE don't model interstellar light absorption. These luminous supergiants are really far away, so light absorption reduces their visual brightness a lot. But because SE can't model it, I forced to use visual magnitude in the catalog, thus computed luminosity is smaller than real.
