Located about 12,000 light-year away in the northern constellation, Auriga, the Tadpole Nebula is a dusty emission nebula and an active star-forming region. The cloud of glowing gas is more than 100 light-years across, sculpted by stellar winds and radiation from an embedded open star cluster, NGC 1893. The name-sake feature of the nebula are two dense streamers of gas and dust that resemble wriggling tadpoles. Potential star forming sites, the “tadpoles” are about 10 light-years long, with tapered tails extending toward the edge of the nebula.

I’ve been attempting to shoot this object for a few years. Each fall, when the tadpoles rose into view, weather or wildfires obscured the night sky and the project was pushed to “next year.” In 2020 I got lucky, had two perfect nights in a row in November with good seeing, and was able to collect just enough excellent data to give this image a go. This is an SHO rendition using standard Hubble color assignment. I relied on Ha subs with an HFR of <2.2 for a luminance mask, incorporating multiple rounds of Pixinsight Multi Scale Median Transfer and Deconvolution to reduce noise and enhance structural detail. I particularly favor the “backlit” appearance of the tadpoles in the blue-green pond of glowing oxygen gas. This feature is reminiscent of one of my favorite objects, Melotte 15, with the dusty “islands” suspended in the a sea of glowing oxygen.

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.
