I have previously attempted this target in bicolor with the 550D, but was not happy with the result or the FOV, so have it another go with the QHY5L-II-M and a 135mm F/3.5 lens.
Not fully as wide as i would have wished for, but with the low resolution of the 5L i think it's better to add the wider field later.

Image is 57x 120 sec exposures of Ha, and 1x 120 sec of OIII.
I wanted to capture the OIII data on previous moonless night when i was using the OIII filter, but the weather said no, so just one single OIII exposure..

Not sure which version i like best though.
