List.tail [ for g in m.Groups -> if g.Success then Some g.Value else None ]

Or maybe you give labels to your groups and you want to access them by name:

(re.GetGroupNames()
|> Seq.map (fun n -> (n, m.Groups.[n]))
|> Seq.filter (fun (n, g) -> g.Success)
|> Seq.map (fun (n, g) -> (n, g.Value))
|> Map.ofSeq)
