M1 The Crab Nebula in HOO

Acquisition type: Electronically-Assisted Astronomy (EAA, e.g. based on a live video feed)

Located in the Perseus arm of the Milky Way, 6,600 light years from Earth, in the constellation Taurus. The Crab Nebula is a supernova remnant that was first observed as it appeared by Chinese astronomers in 1054. It is still expanding and currently measures 11 light years across (http://www.messier.seds.org/m/m001.html)

This image captures Ha and OIII emissions using the L-extreme filter with a SW 14¨GOTO Dobson. The new autocenter feature of Sharpcap 4.1 was used to help guide the scope during the capture of 988 frames. Processed in Pixinsight using Narrow Band Normalization to enhance OIII signal.

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.
