IC1805 - The Heart Nebula in Narrowband - Hubble Palette

Somewhere in the Cassiopeia's constellation, once lived an Alien who was in love by a human, and that Alien was so rich, because this wedding proposal was meant to be seen in the entire galaxy. This is the Heart nebula, known also as IC1805, rich mainly in Hydrogen Alpha, it can be found just to the West of Cassiopeia’s constellation, and lies in the Perseus arm of our Milky Way galaxy. She´s mapped in false color known as the Hubble palette, in the narrowband filters of Sulphur II, Alpha-Hydrogen and Oxygen III with a narrow bandpass of 6nm.

2h:00min = 40 x 180s (Astronomik 6nm SII) - Gain 139 - Bin 1x1 - Offset 50 - Focal Lengh 300mm
4h:18min = 86 x 180s (Astronomik 6nm Ha) - Gain 139 - Bin 1x1 - Offset 50 - Focal Lengh 300mm
3h:30min = 70 x 180s (Astronomik 6nm OIII) - Gain 139 - Bin 1x1 - Offset 50 - Focal Lengh 300mm

50 Darks + 50 BIAS + 150 Flats

The Moon was in the first night of acquisition (when the Ha was shooted) in Waning Gibbous at 98% of illumination in a Bortle scale of 4 (21.63 Mag/Arc.Sec. SQM).

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.
