Orion's Southern Hemisphere

Since I am failing to get round stars even with a 28mm lens on the Star Adventurer for 30 seconds, I tried PHD2 autoguiding in RA with a 135mm prime lens (set to F4) for the first time. Now this looks much better with an 88% yield of good light frames. The winter constellations will soon no longer be in favorable positions in that I pointed the rig at southern Orion which already crossed the meridian. The stars are round enough in the center, while the right side shows elongated stars, an unclarified phonomena I observed before. Anyway, this result would have been difficult to obtain with tracking only. This marks the end of lazy astrophotography.

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.
