The following links take you to places in my primary (chronological) observation logs where I have notes about the indicated double stars. The factual information about the binaries was taken from Norton's 2000.0 Star Atlas and Refence Handbook (Eighteenth Edition, edited by Ian Ridpath, published by John Wiley & Sons, Inc, ISBN=0-582-03163-X).
|Sigma||CrB||7.1||5.6/6.6||1998-06-01||Binary, 1000 years. Nice double|
|Alpha||Her||4.6||var/5.4||1998-06-01||Binary, 3600 years. Difficult due to brightness contrast|
|Delta||Her||8.9||3.1/8.2||1998-06-01||Tricky due to brightness contrast|
|Mu||Her||33.8||3.4/10.1||1998-06-03||Slow binary. Tricky due to brightness constrast, but nice|
|Rho||Her||4.1||4.6/5.6||1998-06-03, 1998-07-29||Slow binary. Nice double|
