After 2 months of cloudy nights, yesterday was the night to try to catch the Horsehead nebula for my 2nd time. The result is much better than last year. However the night didn’t go all smooth.
The raspberry pi wasn’t cooperating… took a while to get Wi-Fi. I have updated the stellarmate during the last months and I couldn’t get it to work properly, couldn’t plate solve, INDI changed the connection to the star adventurer had to fix that also. the polar alignment was difficult to achieve, somehow wasn’t able to get subs with more than 1min. lost almost 3 hours of exposure due to solve all this issues first. And to get the cherry on top of the cake, the fog came also later on, so had to stop the subs…
Even so I am very pleased with the final result. Also first time trying an extender. Next time I will skip it to see the differences. Not the last time visiting this horse

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.
