iss 2nd attempt of captureing it.

Post by TheButcher »


Hey all,

Here is the iss I tried to capture on early Sunday morning about 4 am. The iss was around Magnitude -3.5 and a peak altitude of 60 degress. My first attempt I failed by messing up the exposure and gain and of course the tracking of it. I used my ZWO290mm at around 140fps and was using my 80mm ED refractor with a 2x GSO Barlow. I also tried rigging up a little contraption so I could point and aim with my refractor made of wood. It kind of worked but had to rely on the good old duct tape for safety measures :). I was holding it like a Bazooka and staring into my 8x50 RACI finder the whole time (the neighbors would of loved me as it was going over their house with me aiming for the iss)

Anyway here are the file details if anyone is interested on exposure of it with a mono cam. I will try with my 385mc after I get the right exposure time down for the 290mm. But from this I learned that I need to keep it more steady and lower the exposure/gain a bit more. Gona make some modifications to my new contraption lol. Also you will see in the last photo Jupiter. it was heading that way and thought I would capture it with the same settings so you can see what that looks like.

Frames captured=28993
File type=SER
Binning=no
ROI=1936x1096
ROI(Offset)=0x0
FPS (avg.)=137
Shutter=6.300ms
Gain=232 (38%)
Gamma=50


Thx for looking :)

Sounds like it would have been fun to watch!

Good result.

Great job! Capturing the ISS takes a lot of trial and error with camera settings. It doesn't help that it's constantly changing altitude and brightness during its pass.

Hello again TheButcher. Some nice ISS images here from you here. It's all I can do to track the ISS flybys here with naked eye observing. Thanks for sharing these with us TheButcher, and keep up the nice work.

Thanks all,

I will do more when it comes approaches over deg. The next 10 days in my location it is like 10-20 degrees. But just my luck my ISS app just beeped and the iss will be at 47 degrees and a mag -1.3 within 5 minutes. And it is clear now. Oh well... Originally the weather said cloudy so didn't pay attention.

I was actually thinking of getting a camera tripod mount for it, since my refractor can be mounted on it. I think that would stabilize it better gona do some research. :)

Certainly a hard thing to capture. Good catch!
