IC410: Sky tadpoles swimming in a cosmic ocean

IC 410 is located 12,000 light years from Earth and is located in the constellation of Auriga. The Nebula is a region of ionised hydrogen gas spanning over 100 lightyears across that's carved and sculpted by streams of charged particles called stellar winds emanating from open star cluster NGC 1893 (source: Sky at Night Magazine).

The dusty emission nebula IC 410 is ionized by five hot, blue, O-type stars, HD 242935 (O7.5V), BD +33 1025 (O7V), HD 242908 (O4.5V), HD 242926 (O7Vz), and TYC 2394-1214-1. These massive stars are believed to be the main sources of ionization in the region. They emit high-energy ultraviolet protons that excite the nebula and make it glow. The tadpoles of IC 410 are gas globules, small dense knots of dust and gas that give birth to young stars. They are composed of denser and cooler dust and gas. They span 10 light years.

As for my previous projects, I wanted to obtain a detailed image illustrating the complexity of the gaz components within the nebula. To achieve this I generated 600s subs in Ha, SII and OIII channels and for Ha I only kept the best ones. As I discarded not far from 100 subs, the cumulative imaging time on this nebula is in the range of 70 hours. Also, to better detect the fine structures of the nebula, this version is an HS-HSO version, with SII contribution in the luminance channel of 25%.

As usual don't hesitate to provide your input on the image.

Clear skies!

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.
