Here's a chart from another Horsehead related thread:

For a range of targets, have a look in the Obs Challenge that I and others have had a go at setting. The Jan/Feb challenge can be found in post No 24:

The Challenge is not a competition, but a collection of targets that showcase a selection of objects. These range from naked eye objects, easy to acquire scope targets, and a few thrown in to challenge with their faintness.
Mental.
