The image is form StarryNight Pro, it also displays the magnitudes of the stars.

Which scope did you use?

I have checked this and have the following info.

The Mag 8 star is HR7041

18h43m16.70s +39°18'01.0" * HR 7041 HD173383 Fl: Ba: const: mV: 6.45 b-v: 1.59 sp: K5 pm: 0.016 -0.002

18h43m16.57s +39°18'00.2" * TYC3118-02079-1 Bt: 8.57 Vt: 6.64 mV: 6.47 b-v: 1.64 pm: 0.000 -0.008

The Mag 9.5 star is HR7009

18h38m06.50s +39°40'05.0" * HR 7009 HD172380 Fl: Ba: const: mV: 6.04 b-v: 1.65 sp: M4.5-M5+II pm: 0.006 0.006

18h38m06.48s +39°40'06.0" * TYC3109-02453-1 Bt: 7.95 Vt: 6.24 mV: 6.09 b-v: 1.45 pm: 0.006 0.008

There at several candidates for the Mag 10.5 star. The 2 best candidates are

18h39m52.39s +39°13'48.9" * TYC3105-00099-1 Bt:10.60 Vt: 9.50 mV: 9.40 b-v: 0.93 pm: 0.026 -0.156

18h39m45.83s +39°01'14.5" * TYC3105-00630-1 Bt:10.30 Vt: 9.17 mV: 9.07 b-v: 0.96 pm: 0.091 -0.086

I hope this helps

Cheers

Here y'go

Let me know if I have missed any...

Thanks guys! This confirms that I did split the Tim Horton's double at 94x last night. It was close, but the two doubles were definitely in the orientation shown on the drawing and screenshots.

[FLO]

Thats it, your in the star-splitter club now (I think Ian has some spare badges) 8)

Orion Which scope did you use? Cheers Ian

i was using the orion optics f 6.3 hi-lux 1/8 p.v wave

[orion f6.3]

Not so sure now, if the two stars at the top right are the double double then i am looking at stars between them. on the limt of my 10" scopes limiting magintude (14.5 or more). the star map i think shows the other single double in lyra to the bottom left of the map. orion
