Crab Nebula (M1)

The Crab Nebula supernova remnant and pulsar wind nebula, the first astronomical object identified with a historical supernova explosion (SN 1054 AD). This broad-band LRGB image is based on the data taken in Oct.-Nov. 2019 and Nov. 2023 with Lacerta 250mm f4 PhotoNewton and ZWO ASI183MM Pro camera. Individual broadband and exposures were taken at camera gain 110 and 200. To reduce the effects of poor atmospheric seeing, final images are stacks of the selected 20s and 30s exposures with average star FWHM < 2.5"-3". The luminance data was x2 drizzle integrated to provide finer image scale.

A close-up image of the central part of the nebula (Version B) marks the position of the Crab Pulsar and pulsar wind nebula termination shocks.

Exposure information:
L: 296x20s (Gain 110, bin 1x1), 32x30s (Gain 110, bin 1x1)
R: 829x20s (Gain 200, bin 1x1)
G: 241x20s (Gain 200, bin 1x1)
B: 250x20s (Gain 200, bin 1x1)
Total exposure: 9.2 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.
