C# Need Help Tweaking 2d rotation

I have been trying to fix the rotation for my steering script. I'm trying to get the scripted 2d gameobject to always face the target and while I was able to get it to sort of look at the target it's not looking directly at it. Do you guys have an suggestions for tweaks I could make?

Code (CSharp):

1.     void Seek (){
2.         Vector3 direction = target.position - transform.position;
3.         float moveHorizontal =  transform.position.x - target.position.x;
4.         float moveVertical =  transform.position.y - target.position.y;  
5.                        
6.             float zRotation = Mathf.Rad2Deg * Mathf.Atan2(moveVertical, moveHorizontal);
7.  
8.             transform.eulerAngles = new Vector3(0, 0, zRotation + 50);
9.        if(direction.magnitude > minDistance){
10.             Vector3 moveVector = direction.normalized * moveSpeed * Time.deltaTime;
11.           transform.position += moveVector;
12.    
13.        }
14.     }

 

I've used this for having sprite to face mouse position,

Thank you. I didn't even think of using Quaternion.LookRotation.
