Pelican and North America Nebulae in H-alpha

The Pelican Nebula is about 1800 light-years from Earth and is an active star-forming region. The starlight energizes clouds of hydrogen gas until they glow at the characteristic deep-red "hydrogen alpha" wavelength, which is what you see here. I was particularly excited to see that I'd gotten an image sharp enough to show off the lanes of cold gas threading through the nebula, they look like dark cracks in this image.

I may not have gotten all the data that I wanted, but some things definitely went right. Better guiding, excellent seeing for Wisconsin, very clear skies. Still want to get RGB for this and maybe a mosaic so it's a little less tightly cropped. I went with shorter exposures deliberately in an attempt to minimize guiding problems.

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.
