EARTH AND COSMOS How to peltier cool a C14 SCT
Seeing such as you have here is most likely fast seeing which is commonly caused by jet stream interaction with the middle atmospheric layers. The image will typically look like no wobble but goes in and out of focus very quickly. Sometimes faster than others but typically around 1-3 seconds out of focus and just a second or two in focus. The faster the oscillation the faster the jet is interaction with the layer below.
