Pelican Nebula IC-5070 HaSHO (25-27 August 2019)

OK I'm back in business! The Gods have been unusually kind for a UK bank holiday and gave us 3 decent nightime forecasts in a row with minimal moon interference - enough to do a decent narrow-band even with shorter-then-ideal nights. The Pelican is close to zenith at the meridian so it would be daft to go for anything else. As it happens the data from the last night was so good that I dumped all but a handful of the frames from the first night when processing #firstworldproblems!

This image has just over 9 hours of data - it could have been close to 14 but decided to trade off the signal-to-noise for a sharper image.

The metal prints looked amazing so I'm going for a similar treatment with this one - it's interesting how different the colours look on my laptop versus the desktop monitor it was created on though....

After a modified SHO combination in APP the post-processing in PSPro was pretty minimal. I'm not sure I can eliminate the halo from the Oiii without changing to another set of filters at great expense ... I may see if I can minimise them with another shot at processing....

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.
