M27 (Dumb Bell Nebula)

M27 is a planetary nebula located in the constellation Vulpecula, formed from the gas emissions of a dying star. Although planetary nebulas are usually small, M27 appears larger due to its close proximity. Its centre which resembles an apple core can be readily seen in most telescopes under light pollution while the outer portions can be seen with darker skies or a narrowband filter.

I've always found it difficult to star-hop to M27 by hand, losing M27's orientation in the three brighter stars of Sagitta after starting from Altair and Tarazed.

Being unaware how difficult it would be (in terms of total exposure and processing) to bring out M27's outer shells, I naively assumed eight hours of exposure would be enough. It became apparent when the difficulties came during image processing, followed by realization and looking though other M27 images on Astrobin. In the end, I did manage to bring out some of the outer shells; they’re faint but definitely visible.

As M27’s small size starts to approach the resolution limits of the FRA400 - 2x Bayer drizzling, BlurXterminator, HDRMT and unsharp masking were used to maximize/recover as much detail as possible.

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.
