No, they are not both the same.
This is Astragon game.

I'd suggest not buying this.
Frontier only registered the trade mark it looks like.
The status on another site says:
686 - Published For Opposition
Which I suppose is the same as opening up the trade mark name for others to use (for a fee)?
So maybe Astragon bought the Trademark name for usage on their game?
