It has an extensive advanced search function that lets you find doubles by a long list of criteria.
For making observing lists I often use searches like "constellation Cetus, magnitude of secondary component mag9 or brighter, separation between 0.5 and 30 arc seconds". Search results can be saved as lists in Sky Safari, CdC or CSV format. |
Thanks for bringing this to our attention Steffen.
Yes a great way for all to actually use the Washington Double Star Database. .
One can input what variables one is looking for, a particular range of magnitudes for their aperture etc.Esp useful for those with smaller scopes that are magnitude limited to all but the brighter ones and want to get a taste for what there scope is capable of.
PS: AND glad to see your knowledge on doubles and needed input here once again Steffen !
