This time I attempted to detect a different transit of another star using two different setups:

a DSLR mounted on a big, heavy 14-inch Schmidt-Cassegrain telescope on a very sturdy AP1600GTO equatorial mount and a basic alt-az Seestar S50 all-in-one astro camera, both on the grounds of Hopewell Observatory in northern Virginia.

Can you spot where the exoplanet TOI-1259-b dimmed the light from its host star?

Here are the graphs I made from the data I collected:

Was it at A? Or did it happen at B?

And this graph is what I got from my SeestarS50:

Psst:

Choice A in the first graph was when I reduced the exposure time on the camera from 2 minutes to 30 seconds. Arrow B points to where the transit was supposed to happen, with a 2.7% decrease in brightness. I don’t see it either.

In the second graph, done by the Seestar at the same location on the same night, I again don’t see much.
