Thanks Rick, i have been playing around with different options a bit, when i add more of the Oiii to the Lum, it softens the detail in the Ha, i am finding it difficult to bring out both and decided that teh Ha was a little more interesting. is there a technique to avoid watering down the Ha detail? i was just applying the Oiii at 40% opacity and masking away the areas i didnt want to focus on.

Thanks Rex, appreciate it

Thanks M&T. i did have a go at bringing out the faint detail but it just got too noisy and detracted from the overall pic, perhaps i could do a Paul Hease mammoth 111 hours but even his image was getting noisy in the faint stuff.

Although the 11002 has a lot of read noise compared to most of the newer chips on the market, it has pixels that match better with your FL and its only an issue with narrowband. LRGB imaging isn't very read noise sensitive.

yeah i could do that but i don't have a limitless wallet, i have definitely eyed off the 16200 but the 8300 is almost perfect when you Bin 2x2, i only started doing that for this image and i think i will keep it up, really happy with the results. i think i will leave a camera upgrade until the next step forwards, e.i. when better AO comes to the market. i am not too concerned about the small FOV, most of what i am interested in imaging is relatively small.
