IC443, Jellyfish Nebula

The Galactic Supernova Remnant IC443 (the Jellyfish Nebula), imaged over several nights in January-February 2020 with my mobile setup, the 80 mm f/5.0 SkyWatcher Esprit APO and ZWO ASI183MM Pro camera on the iOptron CEM60-EC mount. This "true color" image is a combination of narrowband (Ha+NII, SII and OIII bandpass) and bradband (RGB) images. The red channel includes [Ha+NII], SII and R data, while the blue is a blend of OIII and B band data. The individual 300s narrowband exposures were taken at camera gain 200, and RGB data was accumulated over 90s intervals at gain 53.

Exposure Details:

Ha: 101x300s (Gain 200, bin 1x1)

SII: 44x300s (Gain 200, bin 1x1)

OIII: 92x300s (Gain 200, bin 1x1)

R: 51x90s (Gain 53, bin 1x1)

G: 46x90s (Gain 53, bin 1x1)

B: 53x90s (Gain 53, bin 1x1)

Total exposure time: 23.5 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.
