IC 1805, IC 1795 - Heart Nebula and Fish Head Nebula

Large emission nebula about 7500 light years away in the constellation of Cassiopeia. Intense ionized gases are driven by the cluster of stars at the centre of the nebula, known as Melotte 15.

Processed as a modified SHO, with Ha luminance for an extra boost!

This was a fun one to process and I'm pleased with the result, but it was frustrating getting all the data. It took 7 nights over the last month with moonlight, poor weather and Saharan dust to contend with. Who said Astrophotography was easy! This has convinced me that I need to set up a dual system to cut down my imaging time. Hopefully later this year...

CS, Tony.

Revised image: Strangely the original image wouldn't plate-solve at all, so after several attempts I created an identical image with a "new" Ha star layer, which solves perfectly!

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.
