V1297 Cas eclipsing binary

No predictions for transit times for this one so trial and error. Sadly missed both peaks and dips.

Got both secondary and primary transits before cloud came in but had hoped to get both peaks to see if asymmetric or not which might indicate star spots. Primary transit is deeper than the secondary.

Cloud stopped play so caught the primary transit but not the secondary. Will try this one again since it transits so fast.

Thought I’d try to catch an eclipsing binary transit since no obvious exoplanet ones to do for last night. First processed in HOPS, since that’s what I know, but that obviously wants to map an exoplanet transit onto the data. Finally processed in AstroImageJ, which charted it quite well.
