There is a thread where comments and scripts can be posted for incorrect star data: COMMUNITY ADDON - Catalog Fixes for SE

There is no reason to create a separate thread for each incorrect star.

Oops, didn't see that. Mind moving this post to that thread?

This should be done by a moderator.

By the way, the specification in the English Wikipedia about the mass of the star may be incorrect.
The German Wikipedia has about 150 solar masses, the Italian Wikipedia 80 - 150. The Spanish Wikipedia also has 150, the Russian Wikipedia 120 - 150.

(It would, of course, be possible that it is only correct in the English Wikipedia.)



I have made a modified script for the Pistol star.
The spectral type 'LBV', as specified in WIkipedia, does not exist in Space Engine.
I have therefore used 'B' for 'blue'. One of the Wolf-Rayet classes might also go.

Code

// -*- coding: utf-8 -*-
// Name: PistolStar.sc

Star "Pistol Star/V4647 Sgr"

    Teff    11800
    FeH     0.1

}

The script belongs in 'addons\catalogs\stars'



The screenshot is from SE 0.973.

Done.

According to Wikipedia: (for lack of a better source)


You can check the citations to find the primary sources -- there appear to be several reliable publications being referenced.

Same idea -- check the citations.

According to sources Luminous Blue Variables are for the most part behaving like luminous hypergiants, in SE a

Class "B0 Ia"

Would make it appear as luminous blue supergiant.
In real sky, though, it's nearly invisible behind its nebula, and without it in SE is showing off a bit.

U Geminorum has the BD catalog number wrongly formatted, BD +22°1807.

This pak is meant to correct the issue.
Place it under SpaceEngine addons/ folder.

steeljaw354, you missed the emoticon. SE classification follows international standards, so no.

steeljaw354, in other words, the place where the the sun is classified calls main-sequence stars "Dwarfs," whereas most international catalogs call it a "main-sequence star" which causes a bit of conflict

Just finished adding in the Tarantula Nebula.
Code
Nebula "Tarantula Nebula/NGC 2070/Doradus Nebula/30 Doradus"
{
    Galaxy  "LMC"
    Type    "Diffuse"
    RA      05 38 38
    Dec     -69 05.7
    Dist    50000
    AppMagn 8
    Radius  90
}


Put this code in Space Engine > addons > catalogs > nebulae > nebulae.sc (if you don't have it, create it).

IMAGES:


Here's R136a1 right in the middle:
