Good evening and thanks to those for commenting on the image I posted yesterday.
I have added a second panel and reprocessed from scratch, but I did include the central portion of the Lagoon in this new image as I was quite happy with the detail there. Yes, I agree the framing could be better for NGC 6559 and I am working on adding two further panels.
So - 45 mins per filter per panel and there is a link to a much larger image on the page.
