I was also at VicSouth, I did not see it in operation at night but it was interesting to watch in solar mode, with a proper solar filter (I believe the addition of that might have been one cause of shipping delay) and a "No alignment" solar mode where it simply panned and tilted around until it found the sun, producing about as good a natural colour image as you could ask for.
Chris I had put an advise stock alert on Testar earlier this week. Got a sms on Thursday 23rd put the order in and it shipped Friday 24th. I called them to confirm and they said they just had a small batch come in and lucky few who had orders got them. So glad I followed this thread and put a stock alert with Testar. It’s bit more expensive than direct but given wait times worth it.
