This is a short event 0.3s in a narrow path but good odds. I'm planning on trying it from Olive Springs if I can get there in time
I was the only observer for this event. Got set up efficiently at the north end of the Olive Springs area, but well before the locked gate at the top of the road where the mining happened. Skies were clear and good. The 76 degree altitude required the 0.5x reducer, so f/5. It didn't slow me much, and while twisted a bit from expectation, I got on target OK visually, and in the Watec a little harder because of scale change. But in the end, the star I thought was it (it stayed stead in eyepiece and I then quickly pushed in the 1.25" barrel and Watec and only one star was on the chip. I assumed that was the target as no others were visible. It was correct and it disappeared correctly.

Target in green, was the only star visible. The red dots is empty sky for reference. |
1/25s time resolution. 0.3s duration. Nice! Reducing bright star occultations by small dim asteroids, is easy. |
