IC-5067 (Pelican Nebula)

This was an amazing target in terms of the immensely strong signal of blue-ish area: at times I felt like I was working with plaster or paint, and not whisps of emitted photons. It proved to be very challenging though too. At the time, I was wrestling with guiding challenges, which I finally tracked down to the guide camera wiggling ever so slightly, only after ruling out practically every other cause. Auto-focus was (and continues to be) an imperfect science. A few of my flats were dubious, and so on. In processing, I ended up making four major efforts on it before finally getting to colors and intensity that I felt good about ... and still haven't figured out how to satisfactorily integrate a couple hours of RGB star data.

My friend @BrianSweeney suggested the target, and we also have some O-iii data that he collected from Phoenix (not used in this version). It was our first attempt at collaboration and one lesson learned was ... camera rotation matters! :-) So we may be shopping for rotators.

tl;dr: Surprisingly challenging all along the way, but worth the effort in the end.

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.
