James Webb Space Telescope at the second Lagrange point (L2) from Brisbane

Now that's just amazing work. I was wondering if the asteroid track should be about twice the length shown in your image showing it for the length of the exposure (38 minutes). I was also wondering how faint you got as there were two other asteroids just outside the east edge of the field of view. You mentioned cropped from full frame. 2005 TO37 [mag 20.3] & 2015 XU138 [mag 21.4] Also a couple just west within the mag 20 range. And several more as faint as mag. 22.

Again, amazing and thanks for sharing.

Hi BMD

Thanks for your response, I appreciate it.

The sub-set of frames used in the composite spanned 31 mins, as clouds damaged others in the session. So effectively, we are only seeing 31 mins of motion which might explain the shortened trail for 1999 XK98. I did pick up the trail of 11478 1985 CD at mag 16.7, but the others were too faint for my system.

Cheers

Hi Dennis,

Again, that's some very impressive imaging! 

I watched a talk about the Tycho Tracker software, presented by its developer Daniel Parrott, put on by the iTelescope folks. Here's the link:

Tycho Tracker (tycho-tracker.com)

This software is designed to detect asteroids (& comets) & analyse light curves (variable stars & exoplanets, too), among other things. Daniel used it to image the JWST as well. You might want to check it out, especially if you're going to be imaging more asteroids in the future  .

Hi Phil

Thanks for your response and the link to Tycho Tracker, I appreciate it.  

I'll jump over there and take a look.

Cheers

Nice!

Thanks Greg, I was very surprised to have picked up the trail of the JWST.

The improved sensitivity of the QHY268M has extended my range by maybe 1/2 to 1 magnitude for faint moving objects.

Cheers
