Heart Nebula - IC1805

Finally another completed project. I suffered from some strange Polar Alignment issues and already thought about buying a new mount. I was very frustrated because I really like my iOptron GEM28 and it performed great at first light. Guiding was very bad and the stacked subs showed a strange rotation. I went to CloudyNights and found a discusion about the PA accuracy of the iOptron iPolar vs. Sharpcap. Seems that I trusted iPolar blindly, because of ist ease of use. I did a PA with SharpCap yesterday and guiding was WAY better. I achieved between 0.4 – 0.8 arc sec / Pixel, which helped with the details in the image. Maybe another Heart Nebula for you, but a great learning for me. Unfortunately other targets in the north are currently above the Limit of the ceiling of our recessed balcony. Hope you like the Image! CS

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.
