PC,
1. I would think that in Australia the crux wouldn't rise or set. But as you get farther north, then the crux would be lower and lower in the sky. I would think that it would appear to rise and set from that location?
Hi S14
That is correct.
Now, you can see the full southern cross on the horizon at 25 degrees north of the equator, briefly, at its 12 o'clock position...
Between 25 degrees north and 25 degrees south of the equator the crux can be seen rising at setting at certain times of the year.
South of 25 degrees from the equator it can be seen in the night sky all year round...
At the equator the dipper can only be seen for 6 months of the year because of earths tilt...
The same applies with the crux...
I've been to Peru a couple times and the Maldives. I saw the southern cross in both locations and I feel like it was lower in the sky when I was in the Maldives. Maldives are basically right on the equator.
Its elevation depends on the time of year and how far you are from the equator
Now as we approach our shortest day, the crux is high in the sky, which is why it can be seen from north of the equator now...
In summer it will be lower in the sky...
If you we're in Peru and Maldives in the same months, then BE says that it should appear lower in the Maldives.
Where are you in Australia?
Tasmania, that little island on the southern edge...
It might be interesting to compare notes with someone near the equator.
Iv done my best and thats mostly what i learnt they are seeing near the equator
2. I wonder if the confusion might be on a little bit of an autistic level. When you face the crux, you are always facing in a southerly direction. But only once per night would it be precisely south. This is because the crux points towards south. It is very close to true south, but not quite exact. So as the crux appears to rotate about that true south point, then it would only be exactly south when the crux is directly on top (or directly underneath) of that axis point. Right?
True. Check out the image

At this time of year i see the crux upright in the 12 o'clock position at 6pm. (pointing south, i would say)
At midnight it sits at 3 o'clock position (pointing east i would say)
At 6am it sits upside down at 6 o'clock position (pointing north i would say)
In south America its the opposite...
At 6pm they see the SC upside down in the 6 o'clock position
At midnight its at 9 o'clock position
At 6am its at upright at 12 o'clock position
I find the term "pointing" to be a problematic.
It always points to the SCP, that center point in the sky, but not always to compass south.
Thats why i use this wording, "when u face the crux, then you are facing south."
Also comparing one star, Polaris, to a constellation, the SC, isn't suitable which is why iv gone to using the dipper cos it spins in the sky as well
So, at midnight its laying 25 degrees from where your compass points south.
So to be precise you would be facing south south west.
Finding true south from here is easy, there are at least 2 methods one can use without the need for any equipment

One way is to use these two bright pointer stars like this

An easier way is like this. Its 4 times the length to the SCP
The FE guys are desperately trying to find an excuse in this 25 degrees when it still can't explain this
Southern cross being seen everywhere at the same time... It can't be both in front of me and behind me can it?
Their explanations are filled with erroneous claims...
And they don't accept my observations, preferring to believe FE propaganda instead.
This excuse used by Gary that my attitude has something to do with it is an absolute joke.
Fact is that he can't explain it and is cut up about it. He won't speak to me now all bitter and twisted.
Im here to drop science not nurse the emotions of people...
On a different note... How was Peru? Did u go and see many megaliths? They fascinate me those structures, all megaliths do...
