IC 1805 & IC 1848: The Heart and Soul Nebula (Marzolino85)

IC 1805 & IC 1848: The Heart and Soul Nebula

The weather forecast for Friday predicted that it was going to be the last clear night in a couple of days. So I didn't want to miss the opportunity, especially since I received my guiding equipment. My goal was to spend at least 4 to 5 hours capturing the Heart and Soul nebula.

Unfortunately, the conditions were not as good as expected. When I had set up all my equipment and was ready to take photos, I noticed how the visibility was getting worse and worse. The humidity was so high that a faint mist formed. Nonetheless, I started my series of recordings. And the higher the Heart and soul nebula were in the sky, the better the individual photos became. But shortly after midnight the guiding suddenly stopped working properly. It took me a while to notice that the lens of my guide scope and also my camera lens were completely covered with dew...

Even though I took more than 150 individual 90s-frames, I ended up deleting around 20% because they were unusable. That means that in the end I only have 3 hours of total exposure time even though I was outside for more than 5 hours. Post-processing turned out to be more difficult than expected due to the less data. But I’m still happy with the result!

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.
