Processing Images – Supernova 1987A (Part 1 of 2)

Supernova 1987A is located near the Tatantula Nebula …… however you will not see it as it has an apparent magnitude today of +13.95. This supernova occoured close enough to Earth so that it’s bright light could be seen with the naked eye with an apparent magnitude of +3 at that time.

Supernova 1987A exploded on February 23, 1987  in the Large Magellanic Cloud.

We are looking at SN 1987A today and will use only 2 exposures to process this image taken back in 2006 by the hubble.

The picture below shows the exposure on the left taken with a F658N filter (red) and the exposure on the right taken with a F660N filter(green).
