M 27 - The Dumbbell Nebula

M 27 acquired using my Intes Mn56 Maksutov Newtonian (127 mm, 762 mm focal length) over two short summer nights. Data taken using the relatively wider bandpass Altair quad band filter, which acts more like a very good light pollution filter.

Processed as an RGB image directly, no extraction of H-alpha or triplet oxygen emission.

Messier 27 was the first planetary nebula discovered, and sits 1,200 light-years away in the constellation Vulpecula. Sitting in the centre is the white dwarf star that formed once it shed its outer layers we see. The peculiar apple core structure of the H alpha content is supposedly formed from material ejection from the equatorial plane of the rotating star, with subsequent material ejection with a lot of oxygen and other species pushed toward the top and bottom regions.

Description: Much simpler process from quad band filtered OSC data only. No diffraction filter based on a comment about Mak-Newt images.

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.
