We will be in Finland towards the end of September and want to try to see the Northern Lights. Any recommendations on a short (couple of days) tour company from Helsinki to the northern part of Finland?
I don't think you'll find any tour companies like that. Take the train north instead (e.g. to Rovaniemi) and you will have more options.
I was in Rovaniemi a month ago. Even though it wasn't "Northern Lights" season, there were brochures for Northern Lights tours available during the colder months.
Any recommendations for a particular tour in Rovaniemi in September?
