DINOSAUR HEAD NEBULA (SADR REGION)

THIS IS A CLOSE UP OF WHAT I CALL THE DINOSAUR HEAD NEBULA IN THE SADR REGION OF THE SKY. I SHOT THIS FOR A FRIEND WHO COLLECTS DINOSAUR BONES AND I THOUGHT IT WOULD BE COOL TO HAVE A MATCHING SPACE T-REX PICTURE TO GO WITH THE COLLECTION. I SHOT THIS WITH 300S SUBS IN HA,OIII, AND SII AND ALSO SHOT A FEW SUBS OF LUMINANCE BIN 1 TO GO WITH THE BIN 2 SHO SUBS. WHEN STACKED TOGETHER IN ASTRO PIXEL PROCESSOR, EVERYTHING IS RESIZED TO 62 MEGAPIXEL. THIS IS A LITTLE CHEAT I LEARNED ALONG THE WAY. I DON'T END UP USING ANY OF THE LUMINANCE SUBS. I SHOOT THOSE 3X30S SO NOT MUCH TIME IS WASTED.

HA=300SX19
OIII=300SX25
SII=300SX25
TOTAL INTEGRATION=300SX69=5.75HRS TOTAL INTEGRATION

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.
