Dear all, I have been away for last few weeks without the possibility to access this forum but I see that it is very lively and as usual with lots of world class images! :2thumbs: I eventually have found some time to contribute with a couple of new images.
The first target is a large planetary nebula that was discovered in 2004 by Quentin Parker, David Frew and Mark Pierce during the SuperCOSMOS H-alpha Survey. It is characterised by a thin faint almost perfectly annular ring with a brighter limb to the north, a structure that is the result of the planetary nebula starting to interact with the ISM. This target located in Monoceros has a very low surface brightness and more than 10 hours on the only Ha was barely enough to show something. Larger apertures would produce much better results :question:

The second target is a more known object even if not so often imaged, the area around Stock 16 and RCW 75 in Centaurus. Here there was much more signal to deal with so the image is less noisy than the former one :)

Both are HaRGB images from Coona, details are on the page.
Hope you will like them, best is to see them at full resolution (option "O" in the website)
