Tadpoles IC410 in SHO (Terri)

Tadpoles IC410 in SHO

Here are the tadpoles, IC410 in SHO.To image IC410 I used a TEC140 with AP field flattener, ASI6200MM camera with Chroma 3nm Ha and OIII filters on an unguided Astro-Physics 1100GTO mount. Narrowband subframes were 15 minutes each. About IC410 from Sky Safari: An area of faint nebulosity approximately 12,000 ly away and 100 light years across. IC410 and it's associated star cluster NGC1893 is a great astrophotography target for the winter months. The gas clouds have been sculpted by the stellar winds caused by radiation from the NGC1893 star cluster. The 'tadpoles' are created when some of the denser gas in the central area of the nebula is driven away by the radiation from the star cluster and creates the streamers, or tadpole tails. The tadpole tails are 10ly long so these tadpoles will make some incredibly large frogs! This nebulous area is fairly young at an estimated 4M years old.

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.
