Splitting the double double

[mtnhkr]

I have a celestron 114 eq and I can't seem to split the double double.  I can find it with binoculars and make the first split, but I can't seem to get it to split again.  How much magnification do I need to get this done?  Is it possible that because everything gets turned with my reflector that I am actually looking in the direction?  Any help would be greatly appreciated.

Thanks

Should be doable in your scope but it needs to be cooled and collimated well. The orientation won't make any difference as long as you are looking at the right stars! ;-)

Try somewhere over x100, maybe x150 if you have the eyepieces for it.

Can you see that they are elongated, or peanut shaped even though you can't split them?

Sometimes the seeing conditions just aren't good enough, so keep trying on another night if you don't get it tonight

I have split the double double with my 120ED using the Baader Zoom and Barlow at x253 many times but have not managed to split it with my 12"Dob even though the collimation seems to be spot on.

I definitely think refractors have an easier time of it splitting tighter doubles. It is doable at x70 or so in a 4" apo refractor, I've split it in a 66mm at not so much more than that, around x100.

I've never viewed it in a smallish reflector but do expect it to be achievable although others will have more relevant direct experience.

I first split e-Lyra in 1973 with a 75mm F/15 achromatic refractor. Used a 9mm Kellner at 125X.

funny enough i have just got in from a semi dark site, i split the double double clean at x100 with a 6" mak and 18mm BST ep

Nice one Jules :-)

I use a 150 Newtonian and find this very challenging, needing good to excellent conditions and x150. The last two evenings the nearest I got was seeing both as peanuts.

Keep at it and you'll get there.

Good luck.

As said above, the seeing condition has the major part of it, then type of scopes and collimation play some role too.

I guess the seeings have been mostly good up here, I can splitt it with MarkIII zoom in 16mm setting with 120ED, that's 56x, and 85x with 8" SCT when it was not best collimated, and 66x when it is. Earlier when I had SW 130P, it was only splitted in 130x.

There had been a couple of time when the seeing were bad, I had difficult to split it in C8 even in 127x.

I've split the double double with the 4" Genesis at x49.....I believe others have done even better (- an even lower magnification). Take your time and train your eye.

Thanks for the advice and encouragement I'll keep trying.

split it friday with ease in both a 12 and 10 newt, and have done it with a 6 inch newt so your scope should do it, but its tight. so good collimation and steady air needed. Next clear night I will try with the 115mm tal i have, to check.
