If stars.mydomain.com is just an ordinary name in the mydomain.com zone, 
then there is no problem with what you show above (except, 
syntactically, you need the trailing dot, as was already pointed out).

If, on the other hand, stars.mydomain.com is a *zone*, then it's not 
possible, because in that case there would be "apex" records (records 
whose name is the same as that of the zone); at a minimum, an SOA and at 
least 2 NS records, which are required for each and every zone. When a 
particular name owns a CNAME record, it cannot also own SOA or NS records.
