I’ll respond to a couple of specific questions in this post, so please do not think that I did not appreciate your replies if I have not quoted them.

Al.
Hi Al,
Yes – these events would be good practice sessions for total solar eclipses! As we got within 10 mins of the predicted transit, each minute appeared to pass like a second as final adjustments were made.

Hi Dave
Here is a 1600 pixel wide strip showing the full resolution at a focal length of approx. 1728 mm.
Thanks Matt, there is a nice Ice In Space community story behind this image.
It started with Mike (Iceman) and Dave (H0ughy) planning to photograph the total lunar eclipse of 16th June from Brisbane, whereupon I felt a twinge of guilt that these guys were flying in from NSW making a huge effort to capture this event.
For my part, I was going to watch the latter stages from the comfort of our study window, but the crushing guilt I felt due to these cross-border raiders, compelled me to meet up with Mike and record the eclipse in the wee hours of the morning.
Then, along comes Tom who posts that an ISS solar transit is to take place some 20kms from home. Friday dawned a perfect day and with so with no excuses, I headed out and managed to record that event too.
I suspect that without the help, motivation and cajoling from this community, these events may have passed me by, so thanks to my extended Ice In Space “family” for stimulating my interest in recording these two most recent and dramatic events.
What a fantastic image Dennis. Can't believe this was only your first attempt at an ISS transit
You've captured it so well and with so much detail. Maybe you'll be able to stack the ISS bits of the frames and get even more detail out of the station itself?
Congratulations on yet another excellent result
What can I say that hasn't already been said... You have the touch of King Midas in that everything you do is pure gold.
Is there any chance you can come to the BAS meeting on the 8th July? We would love to see these at the meeting from a BAS old-boy. i will have some from the eclipse there and I would like to listen to your thoughts on the eclipse and the ISS transit.

Hi Rolf & Tom
Okay, it’s not real pretty but this is the best that I could do from stacking 19 of the frames. At this small scale, it can become difficult to differentiate between the real, core data and unwanted artefacts arising from the number of conversion, aligning, stacking and processing steps involved.
Dennis I have something (almost) right up your alley . Tomorrow afternoon the HST transits the sun at a lazy 4.8 sec duration on the 22km wide centreline through Brisbane. It will be 1.6" in size though and a real challenge one would think! Centreline is here: http://www.calsky.com/?Transitline=&...231&mainbody=0

Thanks Tom, you are a real wiz at these predictions!
Sadly, the Sun will be at an altitude of only 10 degrees and with rain forecast for tomorrow, I don’t rate my chances.
