First light with the ED102 APO!!

I'm quite happy with this result because Orion was just above my neighbours fence after coming from behind the tree for about 30 mins tops. Almost directly in line with the streetlight out the back as well. And I didn't have time to polar align properly so I was probably off by about 5 deg or more. So I didn't want to push the exp much more, 90s was probably pushing it already. I also didn't give the scope time to cool down, and the focus started to drift after about 5 subs. But I didn't have time to re-focus as the target was about to drop below the fence line, I decided to take more subs with slightly off focus than not get any more subs after re-focusing.

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.
