Thoughts on Binaries

[DAVE AMENDALL]

Hi all, I must admit that I have neglected the area of double stars. However, this time of the year there are some fine doubles worth observing,particularly as it does not get dark until late on. Last night, I thought I would give it a try and logged about a dozen. The main ones were Alberio, Epsilon Lyrae Gamma (Y) Delphini and 61 Cygni. A very satisfying half hour before moving on to other things..........Dave

Albireo. 

Sorry, it’s a thing I have that I cannot resist. Like a tic.

No acrimony at all, it’s Albireo. ??

Glad you had a good session. Still waiting for night here ... ?

Nice one Dave, they are always worth a look. I had a quick squiz around a few old favourites again last night. Alberio - snap! Double Double - snap! Then a few tighter ones like Izar and Pi Aquilae. Nice way to spend a lighter evening.

Listen, I already changed it from Alberto which is what the spool chocker thought it should be, I thought I was doing well!

Albeeryoh is a realy nice double, coloured as well. Just about split in a 9x50 finder

Iota Cassiopeia is also a favorite of mine - a lovely triple !

For those not into doubles, you should be ?

The whole sky is stuffed with them at all seasons of the year, fascinating in their variety, some easy, some tough, lots of the theory of astronomy regarding them to learn, least affected by light pollution, what’s not to like !!

Can you tell I like them ?

Okay, okay. I suppose these are gentle ways to tell me I need to get out more ...

... just wish I could get Albireo out of my head! ??

Actually it does bother me as well, at least in my own posts. I often have to do a couple of edits to corrent spelling errors that I notice after I've posted. They niggle me

Neodymium is my nemesis- I have to look it up every time, and even then I’m not sure ?

You should try its close cousin, praeseodymium!

Re Albireo, you can see why many folk prefer more scientific names, although they are less colourful of course (unlike doubles, which are often very colourful, unlike those faint fuzzy thingies). I believe that the name Albireo is in fact a mistake?

Thanks John for the tip on Iota Cass. I have missed this one. I hope to find it at the next session....Dave

My thread seems to have changed to a Scientific latin grammar and spelling quiz. How about Per adem ad Astra or "Whats dat dim wittle lites in da sky Clim?

Apologies Dave - to get back to your subject; I love doubles too. I find the Cambridge Double Star Atlas to be invaluable and I am gradually ticking  them off on the list in that book. A good starting point is to go for the ones marked as 'showpiece'. Many on SGL swear by the Sissy Haas book, I just happen to prefer the Cambridge one. Sky Safari is very helpful too for locating the more obvious ones.

[DAVE AMENDALL]

 Ah yes the Cambridge Double Star Atlas, so many examples I tend to stick to the showpiece ones because of the sheer quantity. I haven't seen Sky Safari.thanks for the mention,worth a look. The Belmont Society Double Star List is worth a Google............Dave

I have a similar problem Gordon.....It's only "it's" when shortening "it is" - no apostrophe otherwise. It's a problem that has worked its way into my head (etc).

Took the words out of my mouth. Binaries are fascinating and compelling targets - particularly for city dwellers

Hi John, one of my favourites too, as is the so-called Easter Egg double.
