Owl Nebula, M97

Revision title: The Owl Nebula

The Owl Nebula (M97) is a small planetary nebula about 2030 light years distant and about 8000 years old. It occupies an area of 3.4 x 3.3 arc-minutes in apparent size, corresponding to a diameter of 1.82 light years. It consists of two concentric shells of gas surrounding a central binary star system. The outer shell of M97 is expanding outward at a speed of about 27 kilometres per second, as inferred from its observed Doppler shift.

Since it is so small and it was imaged at 550mm focal length, I drizzled 3x to pull more detail from the data.

The final image is heavily cropped, the previous image showing galaxy M108 is about 50% crop.

There is a faint, dispersed, outer shell evident.

The image was 3x drizzled to pull as much resolution as I could from the data.

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.
