IC 5070, The Pelican Nebula

A beautiful clear evening last night and a boneheaded mistake that threw a monkey wrench into my imaging session. When I upgraded from my ASI533MC to the ASI294MM I inadvertently removed a spacer that was supposed to be part of the field flattener. Needless to say, I ended up cropping this extensively but even this was not enough to hide the evidence of elongated stars.

Aside from the back spacing issue, the session was still worthwhile for learning more about mono processing. I shot the stars in RGB and then shot the target in SHO. Stars were removed from the SHO image and then combined with the RGB stars. Still a long way to go but hopefully the clouds will clear tonight so I can have a do over with 55mm of back space!

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.
