How do I do it - Sketching a simple open cluster

Open Cluster NGC 1664 in Auriga.
Step 1
Once you've located the object, enjoy the view and try to get an overall impression of the cluster. I also prefer to sketch the object so that north is up and east to the left. This is an easy thing to fix later on but I still try to rotate the field so that north is up if possible.
You can use low power to note any specific colors in stars, star chains and so forth.
In NGC 1664's case here are some features that I noticed @ 37x:
1.) Bright 8th magnitude star SE from the cluster.
2.) Five magnitude 10-11 stars in the cluster.
3.) Y-shape of the cluster, resembling that of IC 4665.
4.) Little asterism ~35' NE from the cluster.
