Computers

A laptop computer allows you to run an imaging session on a deep-sky target with autoguiding, review each of your images as you shoot and connect to additional hardware such as a filter wheel, and even control your telescope mount. Keep in mind that this laptop will spend a lot of time outdoors and will need to be protected from the elements.

Many amateur astrophotographers prefer to use an onboard mini PC or WiFi-controlled device such as the ASIAIR to run their imaging session. This option has the advantage of cutting down on the overall amount of cables running to your astrophotography equipment, and less cumbersome overall.

For image processing, you will need something capable of running demanding software. The computer you use for image processing will likely need much higher specs than your field laptop, to handle CPU-intensive software like PixInsight and Adobe Photoshop.

For both image acquisition and image processing, you will need to install all of the necessary software to run/control your astrophotography hardware and process your images.
