Messier Plus Marathon List

by Wally Brown & Bob Buckner

This list was used by members of the Saguaro Astronomy Club located in Phoenix, AZ for the Messier Plus Marathons of 1981 and 1982. The Messier Plus Marathon was designed to take place during September to provide a second marathon to follow the spring Messier Marathon.

This list includes 75 Messier, 34 NGC and 1 Collinder object, were selected and sequenced for observing site by Wally Brown and Bob Buckner. Of the 34 NGC objects, 30 came from Alan Dyer's "110 Finest NGC" found in the Royal Astronomical Observers Handbook of 1981 and the remainder (+ in OBJ column) being Wally's and Bob's picks. Rise and set times were also bracketed for each section for the site and date.

Certificates of Record of Achievement awarded to top 5 and all ties.

The Messier Plus was not intended to be difficult like the Messier list as early setter and late rise type objects were not included. In addition M40 and M73 were dropped to make list more enjoyable.

The details like constellation, type, location, mag, size and notes added by AJ Crayon and are from the SAC v6.2 database.

Constellation abbreviations are the IAU standard. Type abbreviations: GC= globular cluster, OC= open cluster, PN= planetary nebula, BN= bright nebula, SNR= supernova remnant, Galaxies are identified by their Hubble type. Columns with no entries indicate no data available.

Sizes are in arc minutes, unless noted otherwise.

Of course, the best observing sequence and relative event times are location and date dependent. Data here (for model purposes) is for Phoenix AZ,112W04 33N28, Sep 15/16, 2001, LMT. Time brackets are for first and last event in each section. Sequence is not based solely on rise/set times but on logical, facile rolls through the sky.
