IC 410 • Tadpole Nebula in SHO

I ended up reprocessing this. Even though I use 3nm SII and OIII filters, I think I had some gradient issues from the moon.

IC 410 is an emission nebula in Auriga 12,000 light-years away. The nearby cluster of hot blue type O and B stars, NGC 1893 illuminates the nebula and also emits fierce stellar winds that have sculpted it. What were once two thick, majestic pillars of cold gas, like the Pillars of Creation in the Eagle Nebula, have been so heavily eroded by the stellar winds that they now resemble tadpoles. The leading globules of the pillars still remain and represent the tadpoles heads. Intense radiation from the stars evaporates cold gas from the surface of the globules, ionizes it, and the stellar winds blow it back against the globules, forming brightly compressed rims. However, the stellar winds have so heavily eroded the pillars to the point where they now resemble wiggling tadpole tails, like celestial windsocks flapping in the stellar breeze.

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.
