I feel compelled to mention that the combining chainsaws, big trees, and being up in the air make for probably the most dangerous activity you are likely to encounter. Make sure you have appropriate protective equipment and read up on safety-related practices, and make sure you use/follow them religiously for anything but the most basic cutting. Small things falling on you stop being funny when you are holding a running chainsaw, and big things falling on you are always a Bad Thing.

Stihl and others make small "arborist saws" which are extraordinarily good for trimming branches and probably safer for that type of work than a regular chainsaw -- my brother-in-law uses one as his primary chainsaw (mostly camping-type cutting) with great success.
