Pelican nebula

This is the first light for my Starlight Xpress Trius SX-46. It was a challenge moving from a 1" sensor to an APS-H sensor: I thought I had the back focus from my field flattener spot on (at least, according to the calipers), but had to make a series of fine adjustments in order to make the corner stars round. There's still a touch of tilt that can be seen in the extreme upper left that I'll need to fix, but it's acceptable for the moment.

I tried my hand at 20 min subs for the first time, and miraculously I didn't need to throw out a single one! Fingers crossed I remain that lucky!

The color palette is mostly HOO, as I mapped the SII to a slightly different shade of red. Luminance was set to Ha in order to make the colors pop, especially the OIII which is still quite faint even with 20 min subs.

Overlay/Revision is in the Hubble palette.

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.
