Hi all,

Sequence spans a 6 hour period from second contact (left) at 8:30am (Australian EST) through to third contact (right) at 2:30pm. The shots in between were taken at half hour intervals.

Canon 60D
Baader Hyperion 8-24mm Zoom EP
H-alpha Coronado PST (Personal Solar Telescope)
NEQ6 Pro Goto Telescope Mount
50 images stacked together in Registax 6 for the faint prominences around the solar limb.
5 images stacked together for the surface detail of the sun and one of the Venus images.
Additional 12 images of Venus processed individually and then layer masked on top of the background image in PS CS3.
Captured in monochrome and a false colour added at the end.

Thank you so much Mike and Petra

Yeah it's been good to get a couple of write ups in the paper this last week.

Love it. 50 image stack must have been fun aligning. What program did you use for stacking?

Baz.

Thank you Baz

Registax 6 for the stacking.

Wow, nicely done! Was this captured with your 60D? How did you have it hooked up to the PST?

Thank you very much Dave

I use a Baader Hyperion MkIII 8-24mm Zoom EP. It has a thread under the eye rest that with the aid of a M42-T2 adapter screws straight into the DSLR T-ring. Without it I couldn't get the focal plane of the PST back far enough to hit the sensor and get focus. I know I ideally need a mono CCD shoved in the end of the PST but I'm happy enough just playing with the DSLR setup.
Cheers
Greg
