Re: Split the doubles?
Observing double stars can be a very enjoyable pastime and also doable in bright moonlight when the faint fuzzies are washed out.
Clear skies,

Re: Split the doubles?
There are optical doubles as well as actual double stars, some are fairly easy like Mizar/ Alcor (optical double) but others are quite close together so splitting them takes magnification and good skies.
Really tough/ close doubles may be referred to as figure 8 doubles as they are to close to split but the 2 airy disks look like a figure 8 or a figure 8 with a thin line between them.
There are various atlases that show many doubles of varying difficulty to view.
Cambridge Double Star Atlas is a good one to start with.
Enjoy the views and the chase as double are a lot of fun

Re: Split the doubles?
Also one must take into account whether your scope is equatorially mounted or alt/az. Equatorial mounts will allow a constant orientation with the sky, alt/az do not, they align with the horizon.
Sorry for the confusion,
Steve

Thank you...Makuser wrote: ↑Sat Oct 01, 2022 8:42 pm Hi Razz. A nice double splitting report from you. Lady Fraktor did a nice job of explaining the difference between a binary system double from an optical double as it appears to us from our point of view when one of the stars are many light years away from each other and not a binary system. Also, you will enjoy using the Cambridge Double Star Atlas by James Mullaney and Will Turion as it is the best:

Re: Split the doubles?
If that is the case, then what is the star or light next to Mizar? I see a double star in the lower right but a single at the top left...I thought Mizar and Alcor were the 2 stars right next to each other....

Re: Split the doubles?
Many stars are not just doubles but multiples. Mizar and Alcor is very wide double, it is best viewed under lower power. At high power they appear wide a part (like in that photo). Mizar it self is a double star but with much smaller separation between two components, to separate them one needs to go to higher power. So, on the photo you see Alcor in the upper left and Mizar A and B components in the lower right.

We are all still learning. If we ever stop, it'll get boring. People I look up to as experts claim they are still learning.
