M51 LHaRGB

One of the all-time favorites, M51 and its interacting companion, NGC5195. The data for this LHaRGB image was accumulated over a dozen nights in April-May 2019 with my mobile setup, Stellarvue APO SVA130T@f7 and ASI183MM Pro camera on the Orion HDX-110 EQ-G mount.

The image is a combination of a narrowband (Ha) and LRGB data. The synthetic luminance was produced using luminance and HaRGB data. The LRGB data was captured with camera gain 0, while the narrowband Ha exposures were taken at gain 110.

L: 45x600s (Gain 0, bin 1x1)

Ha: 24x900s (Gain 110, bin 1x1)

R: 26x600s (Gain 0, bin 1x1)

G: 18x600s (Gain 0, bin 1x1)

B: 24x600s (Gain 0, bin 1x1)

Total exposure time: 24.8 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.
