A photo of the Carina Nebula taken using a 8" SCT at F6.3 (1280mm focal length) with a Astro modded Canon 40D, ~59x39 arc-minutes FOV.
During an imaging session of Eta Carina close up, one sub on 9th March had an extra star on it, only lasted for a few minutes at most and vanished. I suspected either a GRB, CR or perhaps a Shock Breakout.
In between the meridian flip of imaging another object, I slewed the scope toward the Carina Nebula to see if the point of light reappeared... if it was a SB than perhaps there was a chance that a supernova would have happened, but no such luck.
The Carina Nebula (NGC 3372) also known as the Grand Nebula, Great Nebula in Carina, or Eta Carinae Nebula, is a large complex area of bright and dark nebulosity in the constellation Carina. The nebula lies at an estimated distance between 6,500 and 10,000 light-years from Earth.
Total exposure time was 1 hour 57 min 30 seconds. Subs captured are 15x30s, 10x60s, 14x150s, 13x300s at ISO800 on 27th March 2018.
