Updated with new version that has longer integration time.

Original description:

This is one of my favourite areas of the night sky and first attempt at it with a very wide field. Quite amazed that I've captured so much IFN as when looking through the files this morning I found I'd lost about half the intended 6 hour exposure time to clouds. So this is just 3.6 hours at f/2 with the Sigma 105mm 1.4. Keep having trouble with coma with this lens but I'm finding that I can still manage it with reasonable results in post processing.

Description: Rather than post a new image I'm just updating this one as it's basically the same. This is a completely new image shot on 13th April 2021. Same lens and camera but longer exposure - approx 6.7 hours with 2min exposures.

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.
