I have been trying to capture the ISS in one form or another. Either a solar or lunar transient, someday direct tracking. Location, time and weather are the main variables that all need to come together to be successful.

 

And that finally happened for me on Aug 17 this year 2019. And the center track line was only 2 miles from home.

 

I used my ES 80mm refractor and ZWO ASI120MM. and proper filter. I had my resolution to high so only captured at 29fps, could of used a higher frame rate, but here is a composite image of 19 frames.

I was excited!

Really cool.  What software did you use to determine precisely when the ISS would cross the sun from your location?  What mount were you using?

Thanks Tim. Calsky.com gives you alerts on location,position,time, centerline etc. The final centerline kept changing everyday right up to the transient.

I used my CGX mount, which I have since sold. Solid mount and tracked really well.

Very nice! I'd say that was a good trade-off between frame rate and FOV or resolution.

Need to get a lunar one. Then try direct imaging/tracking.

It's kind of an adrenaline rush trying to be ready like for an eclipse.

Thanks for the story!

It's a chore as you said, and it won't wait for you to set up, haha, one has to be on-time!

I'm always happy for people to succeed!

Good luck with grabbing a lunar pass now!

I always like to see the different configurations--like yours with the 'tie-fighter' flying 'diagonal'!!!!
