This is a difficult time for the entire United States. Aero, our fulfillment partner,
is based in Ohio. As you may know, Ohio has closed all non-essential businesses. Aero
also provides fulfillment services for P&G and has received an exception from the
shut-down. While they will continue to fulfill our orders, there may be a delay in
shipping our products because they must give priority to medical, personal healthcare,
and cleaning and sanitization products.

Top Notch Guide to Double Stars Review by James
-
This is an excellent resource for tracking down double stars for amateurs with small scopes. After a deftly written introduction, the rest of the book lists about 2,100 doubles by constellation. It gives their position, the magnitudes of the primary and the secondary(secondaries?), the spectral class of the primary (roughly the sequence O B A F G K M), and a description of the pair, including their colors. It also tells you whether the double is a showpiece. That gets you started off right. Great observing guide, with an emphasis on doing rather than reading. Now I would like to read a book of the author's articles, with the emphasis reversed. Love this guide.
