Atik 428ex
Ha filter and OIII filter
Losmandy G11
This picture was taken over two night's. The Ha data was captured on December 3rd 2016. Whilst the OIII data was captured early January. Cloudy skies, caused a delay.
I suspect in 1758, when telescope optics were poor. M1 possibly, did, resemble a crustacean. But I do not see it.
What this picture does show. Is how violent the explosion was.
