Sensor temperatures were -12°C and -15°C.

Processing in PI

- Dark & Flat calibration of L, R, G, B channels

- Cosmetic Correction

- Registration

- Integration

- Crop each channel

- DBE each channel to prepare sup lum integration.

- Create Super Lum channel by integrating L, R, G, B channels with exposure weighting

- Mure Denoise SL,R, G &B channels

- RGB creation

- Delinearisation using HT of SupLum and RGB

- Combine SupLum with a & b color channels of RGB

- Color saturation (and desaturate bkg)

- TGV denoise

In Mac Photo : sat, levels, deflip

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.
