Details:
I downloaded an Ephemeris from the JPL Horizons website for 3I/ATLAS (C/2025 N1) for 2025-07-04 as observed from our back garden in Brisbane and used the data to generate a Database (SDB) in The Sky X Pro which plotted the position of 3I/ATLAS every 5 mins over that period.
After slewing the telescope to the plotted position, I captured 24 images from 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.
After processing in Tycho-Tracker, I was able to generate an image of the trail of C/2025 N1 and an image stacked on the Comet with the showing the stars as trails.
