Sh2-308 Dolphin Nebula in Bortle 1 natural RGB, WITHOUT narrowband enhancement

Many dim emission nebulae are rarely captured these days in their natural state, without using narrowband data. While the benefits of blending in narrowband data are obvious to the Astrobin community, sometimes it's interesting to see an object in true broadband RGB, without any narrowband enhancement. As far as I can tell, this target is rarely imaged these days with pure broadband RGB color under dark skies. It was harder to bring out the dimmest details without having narrowband data, of course, but I think the natural colors in the reflection nebula and surrounding dust make up for that deficit and provide an interesting, fresh take on an old favorite. For this, I revisited some old data from late 2021, using some of the latest processing tools. I hope you enjoy this as much as I do.

For this, I used my ASI2600MC to capture 300-sec. OSC subs the first night, and then added some luminance data using my ASI2600MM with 180-sec. monochrome subs taken the second night. No filters were used, with the exception of the built-in IR cut on the ASI2600MC. I probably should've switched those acquisition times, taking longer subs on the luminance monochrome shots and shorter subs with the OSC camera, but it seems to have turned out okay anyway.

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.
