Looking at the overall exposure per filter it's heavily weighted on Oiii. What's the driver for deciding what the exposure time is going to be for each filter?
Great stuff

I usually process out the channel and see what level of noise is present in each channel and decide whether I am going to accept that level of noise. If not I continue onwards with collecting data. Some objects require a lot more data in one channel over another to lower the noise. The SII really needs a lot more data but the noise in the channel is at a point where it is hard to see even in the full res. I also only use data that has good seeing and tight focus. I monitor what data I discard and what I use purely to produce sharp images. One bad sub leads to a blurry look in images and no amount of sharpening will resolve that look.
There is still noise in the image but I am ok with how it looks overall at the moment. I am still collecting data and may collect a bit more yet in SII and OIII, but that is for my obsessive taste in being noise free. Since I don't use noise control anymore I prefer to control the noise with mega data. It is just a personal preference, but I think it leads to better results.
