      Today Stellarium's development team published version 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.

      It looks like my 2,5 years daughter shows an interest in learning astronomy. Already knows names of all planets and most important moons of solar system. 
      I would like her to learn constellations (she can already identify Orion) and I thought apart from showing her patterns on the sky as well as on the piece of paper it would be nice to get home planetarium. 
      Does anyone have any recommendations for good quality one?

      As you know we use version 0.90.0.xxxx for "unstable binary packages" of Stellarium and those packages may have a new interesting features for testing. In any way version 0.90.0.xxxx has a lot fixes of bugs and it may be interested for users, who are preferred used "bleeding edge" of software.
      I've created this topic for informing community about new interesting features for testing for one side, and get a feedback (with reports about problems, of course) from testers-voluteers in other side.
      Let's try make Stellarium better by together.
      Today we published version with 3 interesting features:
      - support GPS devices to getting coordinates for observer location
      - support RTS2 in Telescope Control Plugin
      - support to asterisms in skycultures (Alt+A and Alt+V to toggle lines and names visibility)
      Binary packages to donwloads (and full list of changes): https://launchpad.net/stellarium/trunk/0.90.0

      As in the Title, there was a planetarium on the antiques and collectables television programme, "Four Rooms" tonight - just finished.  Sold for £1000 but could have done better at up to £3000.  The seller was happy though as he wanted the money for a school to buy an astro camera for their observatory and that was the amount he wanted.
