24*4mins Ha and Oiii this time and a better looking result. The distorted star shapes are from the Oiii data - it seems like my filter may not be orthogonal to the light path. Overall I am quite pleased with this and I can probably improve it further by stacking some of the older lights with the new data and masking the stars to keep shape and colour. This is a steep learning cureve for me but I quite like this result.
