Kitchen Sink Trifid Nebula

Not sure how to describe this one. In 2016 I had shot a number of 2x2 binned, 300 second subs of the Trifid using the 16803 camera at 1.46 a-s image scale. I wasn't pleased with the resolution so in 2017 I installed the 8300 camera and shot 900 second narrowband subs at .43 a-s scale. The detail was OK but the frame was too tight. This month I shot 4 Ha subs with the 16803 and decided to throw it all together.

So the base image is the 120 HaLRGB 300 seconds subs + 4 Ha 1200 seconds subs with the Ha blended into the Luminance and the red channel. Then I pulled up my 24 hours of SHO narrow band data and added the it as luminance data to add detail to the central part of the nebula.

The SHO data was added as a layer in PS that I manually scaled and aligned. I feathered it heavily and blended it at around 75% opacity. That added depth and resolution to the bright nebula.

I wouldn't do this again on purpose but as I accumulate more data on project moving forward I guess there's no reason not to use anything that can help!

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.
