QHY22 vs ASI2600MM (Ivaylo Stoynov)

QHY22 vs ASI2600MM

The ASI2600MM arrived this afternoon and for big surprise the weather got unexpectedly clear, late at night when was about to go in bed... The temptation was irresistible despite that I had just few hours sleep in the previous night and that Moon was near the horizon decided to give a short test

So I have managed to take one image with QHY22 (left) and with ASI2600MM (right). The Moon was about several minutes to rise when the QHY exposure was ready. It took some time to switch the cameras, cool, refocus the main camera and the guide. Definitely the sky was noticeably brighter during the second exposure.

One 600s exposure on NGC 6543, with each camera, Astrodon OIII-3n, auto-stretch in PI.

It is clear that the new technology gives more faint data... The QHY22 served me well for more than 8 years and it will still be in help for the APT development, however there is new workhorse to take the duty

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.
