ISS Lunar Transit

#1

Post by TheButcher »


Hey all,

Here is my first attempt at a lunar transit. The transit was at 4:35pm (NYC Time) so it was still light. The sky was clear but the seeing was pretty bad with 15mph+ winds. I used my 1600mm- Pro with a baader 2.25x barlow with my Stellarvue SVX80T-R.

I tried to get as close to the centerline path as possible from (Transit-finder.com) Then I checked out Google Earth and luckily found a small baseball field with a nice empty parking lot 45 min away from my house.

Now processing was a bit tricky as I have not processed anything like it where you get each frame of the ISS with the moon and also maintaining a nice looking moon. So I took the .ser file from capture using Fire Capture, put it into PIPP then extracted the TIFFS with the ISS in the frame. My FPS rate was about 20FPS so I had about 20 something images of the ISS in there.

After that, I went into Photoshop and created an action to clean up the noise and make each frame better. After that, I went back into PIPP and created an AVI file that repeats back and forth about 15 times. I didn't feel like going into my video editing program to create it to adjust speed and such, but I will do that later on. But with youtube, you can slow the Speed down to .25 seconds if you look at the bottom right on a PC.

I also combined the stacked frames in an image from Photoshop. This was tricky since I never stacked the ISS over the moon and try to bring out each ISS frame to display correctly. But I found a way and it was to have all the frames as layers and then select "Lighten" where you would normally select Luminocity for all the frames. When I did that, then all the ISS frames showed properly, but the moon was off. So I stacked about 800 frames without the ISS that was taken from the .ser file and used that as a Luminocity at 30% over the ISS frames.

I hope I explained this correctly and if there is a better way to bring it out then I would love to know :) But here is What I have below so far for processing it.
