The Dragon's Egg - NGC 6164 & 6165

This was an experiment at a dark sky site last weekend. I've never done narrowband under a dark sky before, and was curious to see how much better it was (theoretically, it should get the same proportional benefit as RGB (in my case 5xfewer exposures), though things like read noise start to spoil that boost, as the background light levels are so low and you're well short of sky limited in the dark site).

Took some OIII of NGC 6164/6165 in Ara to try to get the faint OIII shell around the bipolar nebula. It does seem to benefit greatly from the dark sky - I have got a worse image from considerably more data in the 'burbs.

The weird red bit on the left tip of the bipolar nebular is real - the OIII suddenly stops (at almost a sharp line!) and just the red Ha continues, so you get this sudden transition from a sort of pinky colour to pure red in the HOO rendition. Kind of ugly, but not too sure what to do with it! 😀

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
