LDN1399 / B11 - A Storm Without Lightning

LDN1399 is an interesting dark nebula complex with some beautiful background Ha and O3 luminosity. This field of view contains part of the SNR known as Thor's Lightning. Although, only a bit of the Ha signature is visible here.

Unfortunately, the poor El Nino influenced weather experienced in California this winter did not permit me to capture any O3 data. In fact, the RGB data is very poor and barely usable. But the luminance data was clean and the Ha data was passable so I was able to muscle the image across the line. I knew it was going to be a huge job, hence why the data sat in the queue for five months before even attempting to process it.

I am rather satisfied with the result given the poor raw material that I was working with. I look forward to capturing new RGB and some O3 data this upcoming winter so I can give it another go.

Thanks for stopping by.

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.
