NGC 7640 - a large, near edge on barred spiral

Acquisition type: Lucky imaging

Another image in my processing backlog from this summer: NGC 7640 is a large SBc barred spiral that is nearly edge on to us in direction of the constellation Andromeda. Total of 48 minutes worth of data was captured for this stack of six 8-minute images, each image being a live-stack captured in Sharpcap 3.2 and composed of 240 two-second sub-exposures.

There are a variety of interesting features in this object, including the dust band crossing the large bright nucleus and many other scattered areas of dust. A few bright blue O-B stellar associations can also be seen. The one that looks like a tiny blue comet with a yellow star at one end appears to be a dense cluster of blue-stars in HST data. I think the star at one end is just a coincidental alignment with a yellow star in our own galaxy.

NGC7640 is about 28 million light years away. The view is rich in background galaxies, many of which are tiny spirals, and at the upper left is a fairly rich and distant cluster of dozens of faint galaxies.

This is another target I hope to collect more data on next year to add to this data set and improve the view and detail in the fainter outer regions of the galaxy.

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.
