Horsehead and Flame Nebulas - Second Attempt

In this attempt I'm trying out longer exposures at 58 seconds. As a result, I got a lot less usable data due to stars being out of focus and shaking of the tripod. I only got to use about 60% of the images. It's still a bit noisy, but it still looks better than my first attempt.

Title: Noise Reduction

Description: Found some better ways in Darktable to reduce the noise and bring out more of the dark nebulosity. Specifically, a bright red noise in the dark parts of the image was keeping me from bringing out the rest of the nebulosity. I've found that the higher I set my ISO the more red noise comes out in the darkest parts. I'm going to try longer exposures next time to keep my ISO around 1600 instead.

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.
