The Tadpoles of IC 410 HOO

IC 410 is an emission nebula about 10,000 to 12,000 light-years away us in the constellation Auriga. The center of this nebulous region is the star cluster NGC 1893, and just to the upper left of this cluster lies two structures that resemble tadpoles. These structures are made of leftover hydrogen and dust from the formation of the cluster which is estimated to be only 4 million years old. The “tails of the tadpoles are sculpted by the solar winds and radiation coming from the clusters stars. The tadpoles are around 10 light-years long and are likely sites of ongoing star formation. Their heads are outlined by bright ridges of ionized gas while their tails trail away from the cluster's central region.

With so few clear nights lately IC 410 was high on my list of objects in the winter sky to image do to having these peculiar formations. I was able to setup in my backyard before sunset and was ready to start gathering photons as soon as it was dark enough. This gave me 5 hours to take the 60 subs in this image before Auriga started to slip low in the western sky around midnight.

This narrow band image was taken through just two filters, the Hα and OIII and combined as a HOO format.

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.
