IC 1805 - The Heart Nebula in SHO (Hyperstar!)

Got away to the desert this weekend (Joshua Tree!) and got one clear night of Bortle 2+ viewing (under a nearly full moon, but otherwise great viewing conditions)!

Although I've been trying out my new Hyperstar (with EdgeHD 9.25) and an OSC for a few weeks off and on, this was first-light of my EdgeHD and the Hyperstar combined with the ASI2600MM Pro. Although using the manual filter drawer is not ideal, I'm pretty happy with the initial results so far!

Since time is limited, I focused on just two targets while there: this is the first -- IC 1805 -- the Heart Nebula, in narrowband. This image is just a little over an hour for each filter. I'm blown away by the amount of detail for such a relatively short capture time.

Although I like the traditional Hubble palette, I really wanted more red in the Heart nebula (Since it is a heart!). I used Ludo's technique for non-linear channel combination described here, and I really like the outcome:

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.
