NGC 4725 and NGC 4712

A spectacular barred galaxy NGC 4725 with prominent star-forming ring and a more distant spiral galaxy NGC 4712. This LRGB image was captured with the 250 mm f4 Lacerta PhotoNewton and the ZWO ASI183MM Pro camera over multiple nights in March-May 2020.

The luminance image is a combination of the native L data and luminance extracted from RGB data. The L data was captured with camera gains 0, 110 and 200, while RGB exposures were taken at gain 110:

L: 9x300s (Gain 0, bin 1x1), 69x90s (Gain 110, bin 1x1), 113x30s (Gain 200, bin 1x1)

R: 62x180s (Gain 110, bin 1x1)

G: 45x180s (Gain 110, bin 1x1)

B: 41x180s (Gain 110, bin 1x1)

Total exposure: 10.8 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.
