This image, taken from Iluka, Western Australia on 28 January 2022 is a stack of 46 x30 second subs taken at unity gain and 5'C. This time the Redcat 51 was paired with the ASI 183 mc pro - the reduced pixel scale of 1.98 has improved the overall clarity of the image compared with the Redcat/ASI 294 pairing but the FOV is also narrower. The 183 is a less sensitive camera than the 294 - the 294 also has more well depth which can be seen as increased localised saturation in the 183 image for the same exposure. Overall and on balance, I think the 183/Redcat 51 is a better combination than the 294/Redcat 51 in respect of my needs re wide field astrophotography.

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.
