Description

Hello Friends,

as promised I have revisited the Flying Dragon this year, which is one of my absolute favorites. Its shape is unique and precisely sketches a flying dragon! You may see the wings, the mount and even the eyes. A wonderful, but also very challenging target. You may easily end up in a muddy mess of red color only.

This time I have chosen a larger FOV and collected much more data. Unfortunately only small gaps in the clouds made this project possible and it took 5 days to collect all the data. This is an awful "summer".

I have also uploaded the starless Ha stack to show, how much Ha is this area. Otherwise you may mean, the background was not properly calibrated. But this faint Ha dust is (almost) everywhere. I decided not to overdo it with red saturation. I know, there is a controversy opinion about starless, but i think in this case there is a reason to have a look on it beyond artistic reasons.

One very nice feature is the very faint and tiny PN G084.7-08.0 which is one of the quite new quadrupedal planetary nebula type. This is a fairly new group of PN. I will publish it also separately in order it can be found by the image search if some want to make a session on this interesting PN. Otherwise this tiny value add-on drowns in the flood of images. Not so nice, but very rare and interesting.

Please enjoy!
Rüdiger
