M17 in LRGBHa

I did this originally in RGBHa, but while it gave some good detail, it was too peach.

So thanks to the recent good weather, I got 90minutes of L data, which has made a big difference to the look and colour. Its a really low object from Didcot, but the clear nights made a big difference
