I have no idea what that means...



...but I can check my observing list for those. Here are the colourful ones I've logged:


94 Aquarii: easy split, looks golden and bluish to me
Antares: a bit tricky due to high delta mag, orange and blue (looks more green to me)
HR 2764 in CMa: easy split, wonderful orange and blue (similar to Albireo)
Rigel: easy split, brilliant white and greenish
Xi Scorpii: White (and tight) AB, comfortably split from orange C
70 Ophiuchi: easy split, yellow and orange


There are undoubtedly more, I'm a bit slack when it comes to recording colour.

I'm guessing SL refers to Sri Lanka

And 4m means "from", perhaps?

Is that really necessary? I mean, we're not being charged by character count for posting to IceInSpace :shrug:

Hi,

Attached is a spreadsheet of multiple stars by constellation. The 3rd worksheet along lists well known multiples showing colour, so you can look up a few for whatever constellations are visible on a given night.

If you wish, fill in a few blanks for what colour you see, and send it back, then we can improve the list.

Cheers
