The Pleiades (M45) and California nebula (NGC 1499)

The image is already croped from an original larger image (Nikon DX 1.5 crop factor, APS-C sensor) @ 35mm - f/4.5 - ISO 400

@ 35mm the distortions are the lowest, http://www.photozone.de/nikon--nikkor-aps-c-lens-tests/758-nikkor18553556ii?start=1

Sensorgen.info - a source of digital image sensor information.

Sensorgen presents the information in that form, giving, for each sensor the quantum efficiency, the read noise and the saturation capacity. Headline figures are presented on this page (www.sensorgen.info). by clicking on the camera name you can access a page giving more complete information on that camera, including tables of data for each ISO setting and graphs of the parameters and graphs, which can be linked or embedded in your own material. The work has been collected by Roger Clark at Clarkvision.com.

I acquired from Sensorgen.info the information on my aps-c sensor Nikon D60, which is a CCD sensor, from 2008. They show the best result at ISO 400, where read noise (5.7 e-) is the lowest and DR is 9.6 stops.

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.
