Like Jonathon, I had rubbish seeing plus heat rising off local buildings as I was observing from the balcony of my apartment.
Using a 4" f12.5 Mak with 11mm eyepiece on a Vixen Polarie, I lost lamda Aquarii in the glare much earlier than the predicted time.
Equipment : Manfrotto 475, Vixen Polarie, 4" Maksutov f12.5, 11mm ES eyepiece
Seeing: very poor + heat from nearby buildings. Major turbulence, multiple images visible on occasions. Images reasonably still at times.
Disappearance :
Predicted: 17:59:40 (Starry Night Pro)
Observed : 17:56:15UT [lost in glare of Venus and turbulence/poor seeing]
Reappearance :
Predicted: 18:04:45 (Starry Night Pro)
Observed : 18:05:16UT [ no gradual brightening observed ]
