This variable star shed its outer layer to produce this insane bubble pattern of radiated gases.

Taken using my skywatcher 200P and ZWO 533MMPro with Altair 3nm SHO filters. 

This is a tad over 17 hours of exposure and I’m so happy I was able to get the faint Oiii signal in this ‘explosion’.

It’s processed in HOO palette with 11 hours of Oiii and 6. Hours of Ha taken from my back garden (Bortle 5). 

This one was imaged over 3 nights in September. With a little addition of some rain and some cloud!
