double (or multiple) stars
I am very interested in double-star hunting. It's fun, easy, and,
at times, breathtaking! It can be done even if you are viewing from
a light polluted location or if the Moon is out.
Having viewed or imaged over 1500 double or multi-star systems, the
life lists are very long. The list pages are formatted without a side
menu, so to allow for a wider layout with more columns. They are organised
by constellation.
> links to the double or multiple star life lists:
- part 1 - grouped by Andromeda through
Hydra (A-H)
- part 2 - grouped by Lacerta through
Vulpecula (L-V)
Also, the list pages feature filtering and sorting for easier searching
and analyses. Initially, the tables will appear in "career"
order.

Need to look up more designations?
See the lists at the Lookum
Observatory doubles page [off-line]. An up-to-date
list can be found at the GSU mirror.
The official source reference
is available at the Washington Double Star database (down for maintenance,
to relaunch in spring 2020). An active version of the
database is available thanks to GSU.
