Stuff ups here too last night...

Like you, I had nice clear skies thou a little windy so decided to do a widefield shot...Well stupid me left the usb lead plugged into the camera while DSLR shutter was working away. This resulted in every second image not getting taken...Then halfway through the shots the zoom lense decided to creep down a few mm so I only ended up with 8 subs to stack instead of 20.....

I dont usually plug the usb in but I wanted to check the focus again...
Operater error again....
