Sh2-132 from the Suburbs

Acquisition type: Electronically-Assisted Astronomy (EAA, e.g. based on a live video feed)

Here is Sh2-132, which is a bright region of a much larger nebula in Cepheus close to the Lacerta. This region fits well in my fairly small field of view of around half a degree. Its a pretty decent view of the nebula from my suburban backyard, but I wish I had about 3 times the amount of data. This would have reduced some of the noise induced artifacts. It was tricky to both capture and stack because the nebula was orbiting around Dobson's hole when I was capturing the five 6 minute live-stack images that went into this final image. This produced a lot of rotation from image to image resulting in the Sci-Fi-style star halos composed of multiple superimposed diffraction spikes.

The target has lots of emission regions, but also has tints of blue reflection nebula as well as brown tints caused by dust as well as the very dark opaque dusty regions.

Wish I had captured this from a dark sky site rather than from my backyard because:

1) Its tough to capture the fainter parts of the nebula from the suburbs.

2) I would have been able to capture more than just 30 minutes of data before it went behind my house!

In retrospect, maybe I should have captured this with my IDAS filter, but I would have needed a lot more exposure time than I had available. Its tough to get a lot of time on a target from my backyard because of the narrow view of the sky I have...

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.
