I am using 3 types of charts in the field, in order of resolution:
- AAVSO's constellation charts (which I also use for variable stars).
- Andrew Johnson's Mag-7 Star Atlas's (from Cloudy Nights).
- Taki's excellent 8.5 magnitude charts.
Because I no longer have a 'scope, just bino's these charts are perfect for me. All are printed and in those clear plastic covers.
I keep my good charts (Tirion's and a 40 year old copy of Norton's, indoors).
