SH2-190 Heart Nebula SHO

The Heart Nebula, IC 1805, Sharpless 2-190, lies some 7500 light years away from Earth and is located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. It was discovered by William Herschel on 3 November 1787.

This was another challenging target, even though it is a "bright" nebula, I imaged it through a full moon as this was the only clear sky window. I went full narrowband to combat the moon glow. The data came through better than expected, however it took over 8 nights to complete as I had to throw away over three nights worth of OIII data as clouds continued in and out of the imaging session, with 20 min subs, it ruined a lot of exposure by inflating my HFR. Now the fall clouds have settled in I went ahead and processed what data I had.

I love the Cyan that comes out in this nebula when doing Hubble palate, much the same as its partner the soul nebula.

Hopefully there are clear skies somewhere out there!

Dan.

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.
