My first AP with the great Samyang 135 f2.

Fabulous lens!

Not really good conditions : passing clouds (not much contrast in the picture...), and the Star Adventurer had some tracking errors (maybe due to a not very accurate balancing).

The lens was wide open at f2, and ISO at 400 (best dynamic for A6000).

I use a Novoflex bracket to mount the lens directly on the Star Adventurer. It reduce the charge on the A6000, and it allows to rotate the camera.

The picture was processed en PI, and some adjustments in Photoshop and Lightroom CC.

Now I need to find how to reduce blue halo in the big stars.

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.
