IC 410, Tadpole Nebula, 15 Feb 2013 (David Dearden)

IC 410, Tadpole Nebula, 15 Feb 2013

I started this image already meridian-flipped. Found the Tadpole Nebula fairly easily tonight. The skies are finally clear, but there is some moon and a little bit of gusting wind. Overall conditions were relatively good. Kept the exposures to 180 s to prevent getting the histogram too far to the right. Chiller at 2 °C initially, falling to 0.0 °C. I guess the structure in this nebula is just a bit too dim for a one-shot color camera, at least in my hands.

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.
