NGC 7727: The Peculiar Galaxy

NGC 7727 is a rarely imaged Peculiar Galaxy in Aquarius, a very fascinating and challenging to process DSO.

This is a late-stage merger galaxy NGC 7727 and features two unequal tidal tails, various bluish arcs and star clusters, and two bright nuclei, which are strikingly different. The primary nucleus, hereafter Nucleus 1, fits smoothly into the central luminosity profile of the galaxy. In contrast, Nucleus 2 is very compact, and exhibits three signs of recent activity.

Thank you @SCObservatory for the data from your observatory in Chile for this amazing object. Processed in Pixinsight, Maxim and Photoshop.

Processing this was complex, and in order to pull out the core details I had to use a Lum with a stretch to pull out core details only and blend it in on top of the higher stretch LRGB which got the background and outer arms.

Data provided by SCObservatory, details are:

Imaging telescopes or lenses: Planewave CDK 1000
Imaging cameras: FLI PL 16803
Mounts: Planewave Instruments CDK1000
Software: StarKeeper.it Voyager
Filters: Chroma LRGB 2"

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.
