Happy Christmas SGL,
I m finally getting around to processing images from this year, and this is the last TEC image.
Olly already posted his version about 5 months ago
This is 7 hours of LRGB, in Sagittarius. There is virtually no background sky in this region, being so close to the centre of the Milky Way. What you do get though is a super field of Red / Orange / Golden stars, in what I believe is a dusty region of the sky.
Comparing this TEC data to the two panels of the FSQ data that have M22 in it from my Galactic Centre mosaic, I see that I have the same darker regions in all three images. Perhaps there is a Ha signal lurking in there.
Attaching a cropped version at 100% also.
