NGC 7497 (Connor Matherne)

NGC 7497

Link: https://matherneconnor.wixsite.com/astronomy

Spiky stars and spooky shapes abound in this deep cosmic skyscape. Its well-composed field of view covers about 2 Full Moons on the sky toward the constellation Pegasus. Of course the brighter stars show diffraction spikes, the commonly seen effect of internal supports in reflecting telescopes, and lie well within our own Milky Way galaxy. The faint but pervasive clouds of interstellar dust ride above the galactic plane and dimly reflect the Milky Way's combined starlight. Known as high latitude cirrus or integrated flux nebulae they are associated with molecular clouds. In this case, the diffuse cloud cataloged as MBM 54, less than a thousand light-years distant, fills the scene. Other galaxies far beyond the Milky Way are visible through the ghostly apparitions, including the striking spiral galaxy NGC 7497 some 60 million light-years away. Seen almost edge-on near the center of the field, NGC 7497's own spiral arms and dust lanes echo the colors of the Milky Way's stars and dust.

This was a challenging image to process. From a mixture of trying to obtain a balance of dust to galaxies, as well as bring out as much sharpness as possible in the galaxies. It was definitely a tough one, but I am happy with the result.

I included a version that shows how I have been performing deconvolution and I think it is giving me the best results.

So what I like to do is deconvolution *with no deringing* and then adding the stars back in after to solve the ringing issues. It solves all ringing issues, and gives me sharpness I could never get before with using the deringing tools. The image you see is: original | deconvolution | adding stars back | sharpened with MLT

It's pretty seamless to add the stars back in, and you can't even tell they were nuked the previous step.

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.
