Anyone get this?

I recorded it but not very well

I forgot about it until late last night and so preparation was almost non-existent. As a result I was up until 11pm sorting out the automation script and then ended up with only about 2.64 images/minute and some images with slight trailing.

How does one come to an accurate decision on what exposure time to use for occultations??? I always wonder and never know. In this case I used 10 second exposures to get reasonable brightness (the star was at about 1500 ADU). But I think I could've & should've probably gone down to about 3 or 5 seconds? Unsure where the compromise between SNR and exposure time should be.

Have no idea if my shots will be useful.

Roger.
