Blending tracked MW with foreground

[N1kon1k]

Hey everyone

I’m having a problem blending a tracked MilkyWay with a foreground...

When nothing is above horizon no problem at all... The problem is when I have a let’s say a lighthouse with a MW behind it... often times the tracked MilkyWay makes the lighthouse blurry and bigger than the untracked shot?

Any advice on how to get around this problem?

As far as I understand it the tracking mount will introduce blur since it moves. I think you'll need to take an un-tracked foreground shot, mask out the sky then blend the static shot with your tracked shot in post.

Yeah, the camera's moving... How would you expect a stationary object to not be blurred?
