This was my first real go with the ASIAir Pro. I shot this over two nights. It was incredibly easy to set up and get going. I used the built in polar align function, which I'm not sure works great with the RST-135, since its home position is due west, and requires you to aim the telescope at Polaris before you can run the alignment routine. It still got me pretty close, but I found the Polemaster was a lot more accurate for this setup. The latest version of the software on ASIAir Pro has autofocus, and I managed to use that set to re-focus every two hours. Even the meridian flip was pretty flawless, as all the default settings worked. I would have had more integration time, but the first night got hung up at frame 100 because I neglected to change the default settle timeout value for dithering from 99999 seconds to 30 seconds, and it just sat there waiting to settle for some reason. Other than that, my only wish is that you could save default settings. Most settings are saved, but a few are not, and I find it annoying that you have to double check everything before each run.

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.
