Rosette in HA

The clouds and the smoke haze from the bushfires currently affecting NSW cleared for a single night. I managed 4 hours of 5 minute subs at Gain 111 offset 10 using my new ZWO183MM-Pro.

Processed in PixInsight, this is the first time I’ve successfully used Deconvolution, although a few of the brighter stars have some weird halos, so I guess I need to work on tweaking some of the settings.

Hopefully the fires are brought under control in the near future and the haze clears. I would love to double the integration time and then add the same for OIII and SII.

Description: Still no chance to image, in fact the bushfire crisis has become even worse with fires spread over more than half of the east coast of Australia.

So I have been working on existing data. I have spent much time learning how to use MureDenoise and Deconvolution in PixInsight and have spent a large amount of time learning how to more carefully stretch the data so it stays natural. I also put the background through Topaz Denoise AI to further reduce the background noise. I imagine this last step will become less important once I have the opportunity to gather 10-15 hours more data.

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.
