Recommendations for first doubles?


Recommended Posts

Hi all,

I've been working my way through the Messier List, with my first telescope (Done 21 so far, since late Feb), and would like a break from faint fuzzies. I have read up on double stars, and would really like to have a go at splitting some.

Could you recommend some easy to split, fairly nice doubles for me to try.

So far on my list I have Mizar, and the Double Double.

Cheers

Will the CA of my 120mm Achromatic Refractor ruin double stars?

It's just when I look at a bright star, sometimes there's alot of CA.

Do you need much aperture to view double stars, as when I use aperture masks, the CA is drastically reduced.

Cheers

Faves around at the moment - Algieba, Castor, epsilon Bootes, kappa Bootes, delta Cass, a bit low but you may get beta Monerceros + loads more :)

PS and if you fancy a bit of a challenge try Porrima in Virgo, just split it at 200x in a 5" refractor the other night

Star systems can have two or more stars orbiting around each other - but from here it just looks like a single star in the sky. Soon as you put some magnification on them you realise there's two - because you've "split them apart" :)

Wander along the stars in the plough handle with binocs and see which are single stars and which are doubles. :icon_scratch:

(sometimes you realise there are 4 stars in a "double/double" system)
