From last night. Ha of the Lagoon Nebula. Part 1 of a 2 panel mosaic incorporating the Trifid. I first posted a crop of this and found there was no tilt issue all the stars were round to the corner. It was a CCDstack registration error where the CCDISP plugin did not register several images for some reason, perhaps because each file is 32mb and there were 34 of them!. I used FFT this time and got a perfect registration and stars are round to the corners which makes me happy - PMX just needed tweaking and a decent Tpoint polar alignment and get around the T-Point software errors at present.
I have the rest of the narrowband data and some LRGB. I plan to get the rest of the data over the next few clear nights. The AP RHA is sharp as and it puts pressure on making sure everything else is perfect.
Of interest are those little streaky tendrils near the bottom a bit to the right. I have only seen those before on Paul's recent Trifid/Lagoon image.
I most likely will add some deep data to this next week as well to see what is really there and how far it all goes.
