Overall nice colour and detail but I agree with Paul to me it looks out of focus a bit. Stars should be sharper with an FSQ106 even with the extender (mind you I have never imaged with mine in that configuration).

But the FSQ is a very sharp scope. It is also prone to focus shift with temperature changes. 2C change in temp could see your FSQ slightly out of focus especially with the extender which is amplifying everything.

Do you use a robofocus or electronic focuser? I find with my focus lock I have to have it partially engaged before I lock it otherwise it shifts the focus when tightened.

Greg.
