NGC 4559 with Insert

The initial image was the sum of two years of collected data and 20 hours of accumulated LRGB filter subs.

At that point it was decided to add some detail to the image using data from the MAST Barbara A. Mikulski Archive for Space Telescopes (https://mast.stsci.edu/portal/Mashup/Clients/Mast/Portal.html). The data from the five filters of Pan-STARRS1 for NGC 4559 were downloaded and integrated to produce a single luminance image. That image was registered to an enlarged version of our LRGB so as to create the more detailed insert that you see on the image.

The color of the insert image came from our LRGB image and the detail (luminance) came from Pan-STARRS1 data. The Pan-Starrs1 filters cover not only the visible spectrum, but regions in the IR, and should therefore produce not only a more detailed image but one potentially showing or emphasizing additional structures in the galaxy.

To see the additional detail in the insert, go to the full resolution image and make the comparison.

Enjoy.

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.
