Flaming Star Nebula processing of RASC Robotic Telescope data in SHO with RGB stars

The Flaming Star Nebula IC405 is an emission and reflection nebula is 500 light years away and 5 light years across. The nebula is powered by the irregular variable star AE Auriga, which is thus The Flaming Star. In SHO the reflection wisps do not stand out. If you mouse over the image you will see where I added some of the Blue image to the SHO. Unfortunately the B image did not have much exposure time, so the effect is subtle.

Data is from RASC Robotic Telescope, Sierra Remote Observatories, Auberry, California. RCOS 16" f/8.9 (3550mm focal length), Paramount ME and CCD SBIG STX16803 16MP (4096 x 4096), with SBIG RGB, Ha (7nm), OIII (8.5nm), SII (8nm) filters.

My processing calibrated, registered and stacked the data with DeepSkyStacker. I used Startools to compose as SHO (60SII+40Ha,30SII+30Ha+40OIII,100OIII) and RGB respectively. In Photoshop, the stars were removed using the StarXTerminator plug-in (and manual labor). I used an APF-R protocol to bring out detail (I wrote a PS action based on Christoph Kaltseis's wonderful tutorials. To my understanding it is an unsharp mask on steroids!). Finally RGB stars were added back in as a screen layer.

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.
