Astrophotography from the Driveway

A clear night finally appeared, clouds have been plaguing this particular dark of the Moon. What to do? Maybe do some astrophotography?

I have a new piece of kit, a ZWO ASI Air Pro that has been on back-order since November. With shutdowns in China and the rest of the mayhem it finally arrived this week.

The unit is a little dedicated astrophotography computer that makes a lot of the setup so much easier, while simplifying the snarl of cables on the telescope.

Controlling the camera, filter wheel, and guiding is done through a very nice app on the iPad. In less than an hour I had the basics figured out and was taking images.

A few technical issues to learn about through the night, such as how to best configure the WiFi for use with the home network, how to access and download the images to the desktop computer, etc., but no real problems. I took images through until dawn’s glow appeared in the data, running from twilight to twilight.
