I was pleasantly surprised with the live result of my new filter. From the first sub it was mostly there and after about 5 subs the resolution appeared to be all there. I clicked [save] at 31 subs. Taken from suburban Brisbane using only SharpCap to stretch and colour balance during live view.
Of course, everything is red due to the dual band filter.
