I realise that would be difficult for a visual observer, but magnitude 12 stars would be doable in that 40cm Newt ! The magnitude drop is around 2 full magnitudes, so it would be easily noticed. The ingress and egress are not sharp, so you must consider that; more like a fade away than a turn off the lights.

Thanks Tony, I will give it a try weather permitting.
12 mag stars no problem for my scope.
My "Sky6 program gives a 12.2 star in that position and is occulted around that time,so will print off a chart and get the ARGO NAVIS to do it's thing and see how I go.
I have only ever had one successful Asteroidle occultation that is mainly due to the weather.
Fingers crossed.
Cheers
