Hi Ving

Here are the doubles and the exposures used to capture them.

Rigil Kentaurus & Acrux: Exp 0.25 secs. Approx 20 frames combined.
Theta 1 Ori: Exp 2.8 secs. 12 frames combined. Dark Frames used.
Antares: Exp 0.5 secs. Approx 20 frames combined.

Rigil Kentaurus and Acrux were captured using Vixen x2 Barlow.
Theta 1 Ori was captured using Televue x5 PowerMate.
Antares was captured using Televue x5 PowerMate and Vixen x2 Barlow stacked.

Note the use of dark frames with Theta 1 Ori (Trapezium) and the atmospheric smearing.

Equipment Used: Vixen ED102mm f9 refractor, TeleVue x5 PowerMate, Vixen x2 Barlow, Meade LPI CMOS digital camera.

Cheers

Dennis
