The snr G182.4 +4.3 is a very faint supernova remnant in the very poorly imaged constellation Auriga.
It presents many interesting filamentary structures, it is estimated that this snr is quite young, around 4400 years old.
The processing was complicated because the OIII signal is very weak but I think I managed to get most of the data available over the 30 hours of exposures.
