Thanks Pierre, this object is so faint!
Last night, I downloaded an Ephemeris from the JPL Horizons website for 3I/ATLAS for 2025-07-04 as observed from our back garden and used the data to generate a TSX Pro Database (SDB) which plotted the position of 3I/ATLAS every 5 mins over that period.
This is a stack of 24 frames taken on 2025-07-04, from 9:06PM to 9:54PM (AEST).
- 2025-07-04 11:06:00 UT to 2025-07-04 11:54:00 UT.
- Tak Mewlon 210 F11.5 with Tak x0.8 Reducer/Flattener.
- F10 at 2100mm focal length.
- ZWO ASI 2600 MM Duo camera
- 24x60 sec exposures.
I set the Stack Mode to “Maximum” (Default=Average) as the object was very faint and I wanted all the data to “poke” through the BG.
