IC 1805, Heart Nebula

In the beginning of september we had exceptional seeing over here. Really exceptional. So i grapped my scope and searched for a more difficult target than my usual ones. I found the heart nebula. There are several issues with the image: Obviously the camera had a bit tilting, and the distance to the reducer was not optimal. I had hoped to get a brighter OIII signal with the IDAS filter, but that didn't work well. Perhaps my expectations of an OSC where too high. There are also some background gradients i could not remove - i wonder if these are reflections from my OAG? Processing was also hard, the WBPP-Script really tormented my computer for hours and hours. In the end i used most steps from the WBPP-script and then integrated the images with the ImageIntegration-process manually. But all in all i am happy with the picture - the heart is clearly visible, even the bright fishhead made it to the image :-)

Of course i dedicate this image to my lovely wife! The heart nebula belongs to us all, but my heart belongs to her alone.

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.
