This image was an experiment in batteling the ampglow of my planetary camera. Finally, I succeded, even though the conditions were more than suboptimal. Wind, pollen, a spider choosing the tube as its new home and some haze turning the grey sky over Frankfurt to an intransparent red. After a rain of pollen setteled on my gear two nights ago I needed to clean the mirror. Something that I avoided so far. I must have overtightened the tuberings, mirrorclips or the mirror cell holderscrews. I noticed it in the beginning, but loosing the chance to try something new before the clouds come back was not an option! I decided to live with the heart shaped stars and I got an ampglow-free result :-) Cranking up the gain while reducing the exposure time to yield a higher signal even in the background enabled to properly calibrate out the ampglow with no problems.

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.
