    Yes I realised that,  and appreciated that the sticks were good for broad descriptions of large constellations, but did not (using just HIPs ) have the resolution for fine markings of small asterisms.

    For small asterisms we plan to use coordinates, but this feature is not implemented yet.

    Sorry I didnt understand that :(  Alt A & V, snapshots  to do what, my HIP naming problem or new constellation name problem ?

    Let me show a screenshot - in the future release constellations and asterisms will be in separate layers. We use HIP numbers of stars for the asterisms and constellations to draw the stick figures. I'm sorry, but no special tool for create an asterisms or constellations (but we have this point in our wishlist). The Bookmarks tool (Alt+B) may be partially helpful here, because you can add sequence of stars with HIP numebrs to bookmarks and export this list as JSON file (this file might be opened by any simple text editor like notepad).

    When I upgraded I lost all my settings and it overwrote my old ones, I've only recently got everything back how I like it. Can the next version preserve your old settings or is there a way of putting them safe before upgrading?

    Please be careful when installer of Stellarium is work - I think you are has ticked an option "Remove the main configuration file" in installer.

    Also, on my laptop I have hundreds of tiny Ha regions that overwhelm all other DSOs. I can't find where they are coming from, can anyone suggest what plugin/setting I need to disable to take them away?

    Please go to DSO tab in "Sky and viewing options window" (F4) and check used catalogs.

    No probs I'll go back to 15.2 then. I have also tried 16.0 on another laptop with a different windows 10 build and I'm getting the same problem, it was a fresh install with no previous installations of Stellarium on it.

    OK, I've found where is I made misprint. The fix will be available for testing in next beta (I guess tomorrow).

    BTW Alex I haven't tried this install yet, but is it standalone which I can install in another directory, or does it need to be installed on top of V16 ? I'm just wary of unsettling my stable version esp as it work well with Stellarium SCope

    Yes, you can install it in separate directory.

    I'm still confused. Isn't the absolute magnitude  the brightness that a celestial object would have if it were at a distance of 10 parsecs?

    It's correct definition for stars, but for planets use different definition of absolute magnitude (brightness of body at distance of 1 AU from the Sun).


  7. I noticed something strange when I was customizing the info level. Today the Moon has absolute magnitude 0.21?

    It's correct value.

    I have a request because I have my mind set on a 4K monitor: will Stellarium in the future have adjustable font sizes? We may need that with pixels getting smaller. Looking forward to version 17. That will be super awesome!

    We cannot "resolve 4K" issues, because developers doesn't have 4K devices.

  8. Today Stellarium's development team published version 0.90.0.9732 with support of outlines for deep-sky objects.

    We use the compatible with SkyChart (Cartes du Ciel) format of file for storing an outlines data for deep-sky objects. For example the outline for M42 is represented by this lines:

    05.56401 -05.49880 start  M 42 
    05.56759 -05.39201 vertex 
    05.56635 -05.31749 vertex 
    05.57158 -05.21922 vertex 
    05.57601 -05.21716 vertex 
    05.58830 -05.30164 vertex 
    05.59140 -05.34341 vertex 
    05.59028 -05.37076 vertex 
    05.59008 -05.38175 vertex 
    05.59581 -05.37159 vertex 
    05.59943 -05.47123 vertex 
    05.59912 -05.65838 vertex 
    05.59520 -05.73212 vertex 
    05.58490 -05.68102 vertex 
    05.56948 -05.57675 end

    First column is right ascension in decimal hours, the second column is declination in decimal degrees and third column is command (start, vertex, end). The command 'start' has name of DSO also.

    Our outlines.dat file was partially got from CdC/SkyChart.

    Now we want to get a volunteers, who can help us create a good outlines for big deep-sky objects for two projects - Stellarium and Cartes du Ciel/SkyChart.

  10. Hello all!

    Some time ago I've added into Stellarium few catalogs with deep-sky objects and many users like it. Currently we (Stellarium's developers) planning list of features for implementation on different perspectives (far-, middle- and short time perspectives).

    One of directions of develop the planetarium is works with various catalogs (star and non-star objects). This is reason for my question for you: which catalogues of DSO you are using frequently?

    Any comments, notes and proposals for catalogues welcome!
