Double Stars

Antares
Magnitude 1.09/5.50
2.9" separation. Due to Antares A being 370 times brighter than Antares B this can be a very challenging split because of the glare of Antares requiring a very steady and clear atmosphere . Antares A is a red supergiant larger in diameter than the orbit of Mars and B is a hot blue star.

Taken 5/19/2007 on the summit of Mt. Lemmon (9100 feet) just North of Tucson, AZ.
Astro-Physics 160 EDF with 2x barlow

54 Leo STF1487 Magnitude 4.48/6.30 6.6" separation. This was an easy split. Taken 5/10/2007 Astro-Physics 160 EDF with 2x barlow (pushed to approximately 2.5x) with a Philips SPC900NC webcam. Best of 30 frames. Effective focal length 3000mm, 0.4 arc seconds per pixel.	STT 215 Magnitude 7.25/7.46 1.5" separation. This shot took very careful focus. To be able to actually image a 1.5" separation is remarkable. Taken 5/10/2007 Astro-Physics 160 EDF with 2x barlow (pushed to approximately 2.5x) with a Philips SPC900NC webcam. Best of 30 frames. Effective focal length 3000mm, 0.4 arc seconds per pixel.

Antares A is a red supergiant larger in diameter than the orbit of Mars and B is a hot blue star. Taken 5/19/2007 on the summit of Mt. Lemmon (9100 feet) just North of Tucson, AZ. Astro-Physics 160 EDF with 2x barlow with a Philips SPC900NC webcam. Best of 50 frames. Effective focal length 2400mm, 0.6 arc seconds per pixel.	Albireo Magnitude 3.1/5.1 34" separation. Albireo is a beautiful double system with highly contrasting stars with Beta Cygni A a distinctly yellow star and Beta Cygni B a distinctly blue star. At 34" separation this is an easy split even in binoculars. Taken 5/19/2007 on the summit of Mt. Lemmon (9100 feet) just North of Tucson, AZ. Astro-Physics 160 EDF with 2x barlow with a Philips SPC900NC webcam. Best of 50 frames. Effective focal length 2400mm, 0.6 arc seconds per pixel.
Rigel Magnitude 0.3/6.7 9.5" separation. Often used as a test for the seeing the pair of Rigel can be challenging in a small telescope. Taken 2/27/2008 in my yard in Scottsdale, AZ. Astro-Physics 160 EDF with a Philips SPC900NC webcam. Best of 50 frames. Focal length 1200mm, 1.2 arc seconds per pixel.	Trapezium Taken 2/27/2008 in my yard in Scottsdale, AZ. Astro-Physics 160 EDF with a Philips SPC900NC webcam. Best of 50 frames. Focal length 1200mm, 1.2 arc seconds per pixel. If you look closely at the image the E and F stars are visible.
Epsilon Lyrae (Double double) Magnitude 4.7/6.2 and 5.1/5.5 2.3" and 2.6" separation with the pairs split by 208" or 3.5 arc minutes. Those with very keen vision can split the Epsilon Lyrae into two with the naked eye. Taken 5/19/2007 on the summit of Mt. Lemmon (9100 feet) just North of Tucson, AZ. Astro-Physics 160 EDF with 2x barlow with a Philips SPC900NC webcam. Best of 50 frames. Effective focal length 2400mm, 0.6 arc seconds per pixel.
