10inch LX200Meade F3.3 reducerASI-290m A sparse field with no comp stars with similar flux as target. Also, increasing haze in second half of session contributes to residuals scatter
RC 14" f/8 on EQ8; SBIG ST-8XME, Johnson-Cousins BVRcIc filters 120" exposures. Defocused images. Some clouds at the middle of the transit disturbs photometry quality.
ASI178MM-c, Canon FD 300mm f/2.8, EQ5 Good conditions. Each measurement is a stack of 40x6s or (later) 40x5s. Observations started low (15°) in the eastern sky and required shorter exposures later to compensate extinction effects to avoid saturation. Yellow filter used.
Meade 10\\\\\\\" LX200GPS; SBIG ST10XMECCD CBB filter Processed with artificial star technique at 7x4x10 Binning 2 Used only reference stars C1-C5,C7-C9, C11-C12
RL200, f/6 + ST8, guider RF80/600+G1-0300 partial transit, transit length 233 minutes adopted from literature to findout midtransit time, moon close in the sky
