Merci Daniel pour cette excellente vidéo et surtout pour ton fantastique travail. Des que le ciel me le permettra, je testerais ces nouvelles fonctionnalités. Merci encore.
Great Christmas present for the community! Thanks Daniel. PS : The variability in brightness of satellites on short timescales can be caused by the object tumbling.
Thanks for another great video. Using iTelescopes are 60 second exposures(I believe the shortest with supplied Calibration Frames) useful for asteroid hunting? Do you have any pointers for using iTelescopes?
Example #5 (with the numerous geostationary satellites) was taken using iTelescope T70, which is a camera lens offering a 70 square degree field of view. I used 10 second exposures on it. And while there might not have been calibration frames, I was still able to apply the "Pseudo flat" option in Tycho to achieve a consistent background level. Now, if the goal is asteroid discovery, and you want to reach the fainter magnitudes (mag 19 and fainter), then yes the 60 second exposures can still be useful.
The images are 16-bit. The preprocessing is as follows: (1) the pseudo flat option to achieve consistent background level (2) fix hot pixels (3) plate solve (4) alignment.

A super addition !

@@tychotracker Thanks for the reply
what's the bit depth of these images? Are you preprocessing in any way or compressing into int8 before feeding to the model?
The images are 16-bit. The preprocessing is as follows: (1) the pseudo flat option to achieve consistent background level (2) fix hot pixels (3) plate solve (4) alignment.
is Fast Tracker included in the Standard Version 12?
The Standard version includes the synthetic tracker, while the F.A.S.T. Tracker is part of the Pro version.
