This project has taken 11 nights so far with RGB stars yet to be collected. I have tried to keep the magenta stars toned down and the RGB stars will remove those.
This image is an integration of 24 hours, with SII 240, Ha 450 and OIII 750. There is still some noise present in the data which I am overlooking at present. Although it does not show up on my iPad retinal display.
Edit RGB data now makes the image 29.7 hours of total integration. I have included a smaller version of the new image which can be compared a little the previous version. Detail levels have not changed much but the colour data has had an impact to the overall colouring of the image.

As for iPad, I have also noticed that the retina display does not show faint detail as well as computer screen, adjusting brightness does not help much.
Great stuff. Like the palette and the detail is marvellous. Well done.
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?

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.

Thanks for the comments. I am not certain about faint detail not showing up but the noise levels are harder to see with an iPad.

Thanks Marc, I am particularly fond of this palette these days. I think it gives a real 3D feel to many objects.

It's good to see you getting good results with your gear.

Thanks Clive, I think there is a bit more data to get yet. This rig is relatively trouble free these days. It is the other rig that is playing up. The beauty of having two working remote observatories is if one goes down the other is usually working and that eases the frustration.

Cheers,
Rick.
Yes I have noted your tastes in fluro have increased.
Amazing effort Paul with deep results. I really like your explanation to David that talks thru your approach to noise and sub review. Makes the result even more significant.
Beautiful Paul - amazing structure and not too noisy on my monitor.
Merry Xmas,
John K.
Thanks John. Nice to know the noise level is low.

Actually my favourite area is down near the five o'clock position and around there near where the Ha, SII and OIII sort of merge together. It gives the impression of looking through the gas and seeing wisps of detail. I think there is something for everyone in the this object though.

Thanks Graeme, I reckon it depends on the time of day you view this image. During the day the light levels seem to influence how your eyes see things, but yes it is a little darker than I would normally present. I guess I am looking for that dividing line between clipped and mood setting. At least you got to see some of it being gathered last weekend.

Thanks Greg, I hope this sort of result helps to convince you of going long on the subs and getting lots of integration time. Perhaps even automation.

Thanks Phil, with some careful processing I am hoping to present this as a standout from previous Rosette images presented around the traps. Some more work to do yet though.

I like the colors too.

Thanks Allan, the detail level on these big objects always presents great opportunities to give a great result. It might interest you to know that I sort advice from several people as to saturation on the colour and was told to check the luminance by several. That really impacted on the colours which I think work well. One of my previous images I used a very similar colour palette and I quite like the look myself.

Posting my own meager version soon.
Everyone starts from the same position really, so don't discount your results. Equipment certainly makes a big difference but I can afford to be more choosy with automation in place. I will be looking out for your image now.
