Private Observatory
Lat: +51°, Long: +01° - Instrument: 400mm f6.8 ODK, ST10XME, J/C Filters
- Photometric band: Rc
- Time standard: Gjd
- Brightness in: Flux
Note:
240 second exposure through Rc filter. GPS time control. Clear & cold, very high moisture (no wind). Scatter increased during observation, suspect dew formation on mirrors. Second upload of observation, this time with standard ensemble photometry, previous upload used limited comps for Spring joint observing campaign.
