Pelican Nebula - LRGB+HA

Slightly different take on the Pelican Nebula. The usual orientation makes this nebula resemble a pelican. Since my original framing ended up showing it upside down, my plan was to flip the image after completing all the processing. However, I feel that this new orientation grew on me. Looking a bit like an open campfire.

I wanted to collect HA data and use it to highlight the nebulosity in this object. Being my first blending of HA with LRGB, I spent quite a bit of time tweaking the blend and trying to get it just right.

Just received a set of narrowband filters for father's day gift. I'm capturing some OIII and SII images to use along with the HA data to create a narrowband version of this image. Looking forward to that in the near future!

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.
