Observing List Maker

If you would like to have an observing list custom made to your specifications please enter that data in the box provided. Pertinent data include what portion of the sky you can observe (RA and Dec limits), what separation you can observe (lower and upper limits), and what magnitudes are observable by you (both primary, secondary, and delta-mag).

In addition, if no magnitude information is provided should we include the selected object?

Also, do you wish to observe infrequently observed (N = ?) objects, or those which have not been observed for a long time (DATE = ?)?
