Details:
Last night I've been staring at my ISS animation and spotted a black cylindrical shape object with a bright blob on its top which I could suddenly identify. At first sight it looked like a russian spacecraft and also looked like it is docket to Pirs module on the Earth facing side of ISS. Which was awkward because I knew for a fact that there is no spacecraft docked to Pirs at the moment.
There is only one spacecraft around there which is Soyuz MS-08 (okey and Progress 69 too at the very top of the russian segment docked to Zvezda module :) ). So I had to come to the realization that the low 50° pass just happened in such angle that I am looking at ISS from sideways instead of upwards.
Wait up, what??!! Spacecraft on the "far side" of the station? That's coool!! :)
I think when has passed its highest altitude I rather begin to look at it from behind, just from the correct angle to be able to see MS-08. We see ISS from sideways when ratiator blocks us from seeing it fully. As frames go by MS-08 comes out from radiator's obstruction and shows its beauty, black body with white top .
I have never ever spotted spacecrafts docked to the "far side" of ISS :D
I used a 10" dobsonian telescope (250/1200 Flextube) with a Zwo ASI224MC color camera and a TeleVue 2.5x powermate to record a video at 60fps frame rate, after carefully aligning my Telrad and my main scope.
Video recorded with Fire Capture at these values:
Expo: 0.798ms
Gain: 210
After the bright ISS pass I processed the video first in PIPP. It turns a video to single frames.
Then I carefully analized the frames by checking each and every one of them. When my manual tracking was accurate, I could manage to record between 4-7 sharp frames right after each other. Those can be stacked, for stacking I always use Autostakkert 3.
I eventually ended up with 4 stacked image, so I've made an animation in Windows Movie Maker after post processing all 4 frames in Photoshop.
The picture about the ISS showing the currently docked spacecrafts is from Nasa's ISS Blog.
