Bit slow with the processing on this out of season/year HOO image.

Well done for capturing such a difficult target. I've tried this myself before using 30 minute exposures and got basically nothing.

The OIII is a mix of 15 & 30 minute with an Astrodon 3nm, the background sky is much better on the longer exposures... guess the 15 mins. could be just adding noise as showing hardly any signal above a murky background sky.
