NGC 660

A peculiar polar-ring galaxy, NGC 660. The complex structure of NGC 660 is believed to be a result of violent interaction between two galaxies that occurred around a billion years ago forming a prominent star-forming ring. The prominent warp in the plane of the ring is probably due to the tidal interaction with the nearby galaxy UGC 1195 seen in the wide-field image (Version C). The image is a combination of LRGB data taken over several nights in October 2021 with the 250mm f/4 Lacerta Photonewton and ZWO ASI294MM Pro camera. The luminance image is a combination of a series of 300s and 90s exposures taken at camera gain 0 and 108. The RGB color data is comprised of 180s and 300s (R) exposures taken at gain 108.

L: 56x300s (Gain 0, bin 1x1) and 77x90s (Gain 108, bin 1x1)
R: 35x180s (Gain 108, bin 1x1) and 8x300s (Gain 108, bin 1x1)
G: 38x180s (Gain 108, bin 1x1)
B: 40x180s (Gain 108, bin 1x1)
Total exposure: 12.9 hours

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.
