IC1805 Heart Nebula in Ha (starless) (Greg Harp)

IC1805 Heart Nebula in Ha (starless)

Another break in the clouds gave me time to capture some imagery of the Heart Nebula, IC1805. This is a tight shot because I wanted to use my AR152 reduced to f/4.3 and get as much detail as possible.

Unfortunately the Moon was nearly full, so I limited the shooting to Ha for that night. The result of that and the lengthening nights here is 8 hours and 20 minutes of integration. Hopefully I can return to this target soon and gather a similar amount of Oiii signal. I'll add Sii if I get the time, but I currently have in mind another HOO-like exposure (with the synthetic green channel based upon function of Ha and Oiii).

In the meantime, there is this. Lots of nebulae with abundant Ha signal look especially beautiful to me once the stars are removed. The missing "noise" of the stars allows my eyes to focus more on the wispy clouds of gas and dust.

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.
