SN 1987A (with sprites)

Post #1by Gurren Lagann » 16.10.2020, 00:42

Yesterday (as of the time I made this post), user Duglis asked about an addon including SN 1987A. Now that dream has been made a reality, and with sprites!

The "blob", which delayed the discovery of the neutron star to December 2019

Special thanks to:
Duglis - For posting the idea, and motivating me to make this addon
LukeCEL - For the nebula-making tutorial, and helping me (directly or indirectly) with issues of the mesh
pedro_jg - For confirming the correct orientation of the rings
Tziamtzis et al. 2010 - For measuring the orientation of SN 1987A
Cigan et al. 2019 - For finding the neutron star remnant and measuring the "blob" obscuring it

greetings , nice job !

There is a little issue with this addon ( not really a problem ) ,
and i would like to ask if anyone else has experienced this.
On my Mac there's always a red pixel visible at the SN's position , even from millions of lightyears away.
I've never seen this on any other addon.

Any ideas how this can be adjusted ?

Rufus T Firefly, this is a known bug with sprite nebulae in Celestia 1.6.x. It's been fixed in Celestia 1.7.0.
My Addons: viewtopic.php?f=23&t=19978 • Discord server admin
Celestia versions: 1.5.1, 1.6.1, 1.6.2, 1.7.0, and some unofficial versions like Celestia-ED
