Here we present one of the first amateur images of the G182.4+4.3 supernova remnant.
G182.4+4.3 a very faint galactic supernova nova in Auriga, about 50 arc minutes in diameter. Not unlike the well known Sharpless 224, G182.4+4.3 shows a lot of interesting filamentary structure. G182.4+4.3 is estimated to be quite young, around 4400 years old but with a large, 22pc radius.
This image is a combination of 25x1500s, around 10 hours integration time using an Atik 490 CCD Camera and a Sky 90 telescope with an Astrodon 3nm Hydrogen Alpha filter. Note: The narrowness of the filter will attenuate any NII emission.
Due to the very faint nature of G182.4+4.3, it is hard to visualise the supernova remnant amongst the Milky Way starfield. Three images are presented here. The simple stretched version. A second version with the stars aggressively removed, and finally a negative image, which best shows the extent of the emission.
The background further complicated by general backgound fluff.
