NGC3718 and Hickson 56

Everything that could go wrong with this image has gone wrong.

The Luminance data was captured over three hazy, murky nights. I lost half of the Red sub-exposures. I then collected 3 hours of Green and Blue but forgot to turn off the 2x2 binning. I had problems with guiding on one side of the meridian and had to junk about 2 hours of Luminance data.

It's not pretty, it ain't going to win any awards, but short of junking the whole lot (which I seriously considered!), here it is.

3 hours of Luminance (10 minute subs)

4 hours of rubbish colour data

:-(

NGC 3718 is a gravitationally distorted galaxy lying about 53 million light years outside the Milky Way. The galaxy below it in this image (NGC 3729) is interacting with the larger galaxy and it's distorting the arms of the larger one.

To the right of the larger galaxy is a faint clustering of very distant galaxies. This group, the Hickson 56 group, has five gravitationally-interacting galaxies in it. It's a mind-boggling 400 million light years away.

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.
