wookie1965 Posted September 3 Share Posted September 3 Does anyone know if you can search for SAO numbers in Sky Safari please. As a lot of people know I like double stars and I prefer to use the SAO catalog, I have just got a bluetooth dongle which makes using my phone and Sky Safari much easier to use.

Gfamily Posted September 3 Share Posted September 3 Yes, it seems you can 1 1 Link to comment Share on other sites More sharing options...
chrisecurtis Posted September 3 Share Posted September 3 Just searched (SS 7Pro on iPad) It listed 10,000 objects (the search limit), most of which are SAO catalogue items. (it also listed Sao the mag 25.8 moon of Nepture, asteroids Saotome, Sao Paulo, and Saone, two SAOCOM artificial satellites and about a dozen "features on Earth") 1 1 Link to comment Share on other sites More sharing options...
chrisecurtis Posted September 3 Share Posted September 3 I should mention it gives magnitudes, separations (and much more) but not position angles 1 1 Link to comment Share on other sites More sharing options...

Zermelo Posted September 3 Share Posted September 3 I often use the SkySafari "Planner" function to choose doubles. You can filter on magnitude range, separation range and constellation, amongst others. You can also filter on catalogue (SkySafari uses several), though it's not always obvious what to enter in that field for a partiular catalogue. So, for example, if you were interested only in SAO doubles, entering "SAO" won't work; you need to put in "Smithsonian". Once you have your filtered search list as you want it, another nice feature is that you can immediately turn it into an observing list and save it. 2 Link to comment Share on other sites More sharing options...
josefk Posted September 3 Share Posted September 3 I use the planner @Zermelo but never for double stars and i've just learn't something from you there re. nominating the catalogue (and a quick test with Burnham just worked a treat). A quick Q if i may - I see how to filter by magnitude but how do you filter by separation? This would be great to create a super targeted (i.e realistic for a given scope) set of observing lists. 1 Link to comment Share on other sites More sharing options...

You need to click on the "show more" just under the Magnitude filter. 2 Link to comment Share on other sites More sharing options...

Fabulous - i don't recall ever opening that lot. 🤣. The sky is now indeed my oyster. It's an app that just keeps on giving - seriously. 3 Link to comment Share on other sites More sharing options...
Zermelo Posted September 3 Share Posted September 3 Another useful feature that doesn't exist (yet) would be to filter by the component magnitude difference, as well as the overall magnitude. Sometimes I like to look for wider, but difficult, doubles with a bright primary and dim companion, and other times I might go for dimmer pairs that are tighter, but close in magnitude. 1 Link to comment Share on other sites More sharing options...
chrisecurtis Posted September 3 Share Posted September 3 I was using pro. I think, by chance, I happened to look at a few from the search list that did not show a PA. Catalogues are like that: incomplete! 1 1 Link to comment Share on other sites More sharing options...
