Seldom Imaged... G132.7+01.3 Super Nova Remnant RGB+HO...with wider field mono Halpha mouse-over

Mouse over is a monochrome Halpha wider field to provide context, a 5nm Astrodon filter was used.

G132.7+01.3 Is one of the largest Super Nova Remnants in our galaxy. Measuring 186x258 light years across. This is a very dim object that is most often overlooked when folks image the famous "Heart Nebula".

Seen below in the monochrome Halpha, the SNR is nearly centered in the frame. A thin shell with shock boundries clearly visible, just below the "Fish Head Nebula" and the "Heart Nebula". This image was taken with a 3" F/4 astrograph, STL11000M, and 5nm Astrodon filters in 2015...

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.
