M27 (The Dumbbell Nebula) in HOO

Here is another example of what could happen to our Sun down the road. I think these Gas Emission Nebulae are some of the most interesting objects. Its a shame that most are so small - but not this one! Like the Helix this knots of photoionization fronts. These areas where ions are formed seem to float on a blue sphere of reflective gasses.

Expansion rates indicate the nebula began expanding around 10 to 15 thousand years ago.

This is an HOO mix. The OIII competes well with the Ha on these types of planetary nebulae. There is some nice SII that focuses on the knots but I have not yet figured out how to use it! I'm not done here.

20 minutes subs were used. 27 OIII and 19 Ha. 15.33 hours.

NOTE: as of 2019-01-12 the uploaded red-edit also contains 20 SII subs. Total now is 22 hours.

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.
