SCOM Customfield1 Data Retrieval through Powershell

Hi Geeks,

If I click on the properties of an alert in operations manager console and navigate to "Custom Fields", I have the server name in CustomField1.

I need to retrieve the server name from the customfield using powershell. I am aware of the Get-SCOMAlert command and I have had no luck trying out this: Get-ScomAlert | Select "CustomField1". Any idea on how to do this? This is my first question on a forum, hoping to get a reply soon. Thanks in advance :)
