Simbad didn't find A0535+262 just "HD 245770" or "AO 0535+26" at similar position and mag 9.5.
Yesterday I did a 3 x 5 minute series (ref: 125 tau), and 5 hours later made 8 x 5 minutes series (ref: 136 tau), curious if I can find variabilities.

To remove doubt of diferent/wrong ref. star, I quickly tried 125-tau for the 2nd series and saw a similarily lower blue end for the 2nd run.

Indeed, reason to return for me was to try a series till clouds arrive, from what I could see a minor Ha-variability, hope not because of cloud veils:
