Spring Moon (OAG Test1?)

I was using the moon to set the focus of my new Askar Off Axis Guider (OAG) for the Edge800 setup. I was happy with the Orion ST 80 system I was using, however, I wanted to use it for other things such as the 2024 Eclipse so decided to get an OAG. It was a success as I set focus of the ZWO ASI120 guide camera to the main camera focus. Before I go any further, this guide camera will not work well or at all with the OAG and have a better matched camera on order - the ASI220. Although it did not detect any stars while on M43, I did manage to guide on some other targets but more about that in another post.

After three years I finally imaged the moon with this telescope. While doing the test I decided to play here for a bit with the ASIAIR. Typically when doing high resolution work on the moon it is best to make a short video and then stack it to make the image. While I did find and use the video function on the ASIAIR, the videos I thought I made were not saved - Oh Well! When all else fails, read the directions.

I did manage to collect some test images. This particular image was a 500us (0.500ms), Gain 0, shot taken with the ASI294MC Pro and about 15 minutes of processing.
