NGC 2903 in LRGB (and asteroid 447 Valentine)

It has been a while since my last image. Finally, the clouds and moon are gone.

NGC2903 is a barred spiral galaxy, roughly 30 million ly away. Two nights summed up to 8.5 hours of exposure. Stars are a bit bloated due to unsteady guiding caused by wind. However, I quite like the results in both detail and color.

Luminance was stacked and deconvoluted, then combined with the RGB image with the LRGB combination in PI. Image was cropped with final touches in LR.

Update: a gif and some info of the asteroid is in Version C

Stay well in these crazy times!

Description: I stumbled across this bycatch, 447 Valentine, a minor planet belonging to the main belt asteriods. The asteroid is just right of the galaxy. Animation was build from all 68 calibrated, aligned images from the luminance channel. Images were taken during two nights, therefore the gap.

I identified the asteroid using the JPL site https://ssd.jpl.nasa.gov/sbfind.cgi#results.

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.
