Been on my list to detect exoplanets for ages and finally got around to doing it. The data is messy and needs to be improved but it does fit the transit. Target star is over-saturated so never going to be good.

Top line shows curve before detrending – probably due to airmass changes. Quite serious clarity variations during session.
