My first version of M31.
I used 93 subs of Ha, 100 subs blue, 119 subs red, 100 subs green and 100 subs luminance.
I have thrown away 47 subs of Ha due to haze or high thin clouds.
With the latest Ha upload I can use 45 out of 70 also due to haze or high clouds.
So in my next try I can use 138 Ha subs in total.
In this version I combined Ha with the red channel using the NBRGBcombination script in PixInsight but after my experience in using the script I'm not satisfied.
So I did a search on the internet and found the follewing:

In this video tutorial a other technique will be shown in combining Ha with the LRGB data.
The first part of this video can be skipped, look from 55:20 minutes.
Maybe interesting.
I will use this technique in my next try.

Mike,
That's a really impressive improvement on what was already an excellent result. That certainly illustrates the benefits of being in a syndicate, when the amount of integration time necessary to reveal 'hidden' data can be done. Outside of a syndicate, that amount of time would be too expensive.
Thanks for making that submission in the first place Mike, I certainly would never have thought to have done so. Now looking forward to M33.
Cheers,
Ray
