Greetings.  I got up early today to set up my 10" reflector to capture the ISS.  I thought I would share a few pics.  It was a nice bright pass (magnitude -3.6) and I was surprised when I first saw it that I saw another object not too far away.  I joked to myself "which do I point to?".  Checking the mission page it appears what I saw near the ISS was the SpaceX Dragon craft which had just departed from the ISS.  Nice accidental observation. smile.gif

 

These were taken with a 254mm f/4.7 Reflector on my atlas mount with a 2" 4x Barlow.  Exposures were 1/2000 sec at ISO 1600 using my Canon T4i.

It could be better but I tell you this was not easy.  I must be nuts, getting up at 4am to go out in -11 F air temperature to get everything set up. smile.gif

 

Clear skies,

Eric

Nice job! You got some good detail out of the ISS. Not an easy task.

Thanks!  Needless to say I had on many layers.  3 hats and a hood, 3 scarfs, 4 shirts, big warm jacket, thick warm socks, boots, hand warmers.  Only thing that got cold was my toes and occasionally my hands because I had to use my fingers now and then.  Funny having to handle things like a hot potato to avoid cold burns then also how the cables just don't want to bend.

Thanks!  The whole time I was predicting a less than 50% chance success.  This was the highest focal length I have attempted the ISS with.  4775.2mm at f/18.8.  I was not confident about focus which I spent at least 30 minutes on.  Also I wondered how well I could get the telescope on target using my little red dot finder from the back of the scope .  I think it is time for a more proper telrad.

Great job! and with stills which I imagine is much more difficult than video with a few lucky frames!!!

I hope now you finally realize the ISS is real and the Earth is not flat:

Thanks!  You're right.  At the focal length I was at it wouldn't have been a big deal to lose the resolution I would have if I went with video.  Maybe I'll try that next time.  I was impressed with the camera in continuous mode that I noticed no significant delay between frames the entire time.  I also considered using BackyardEOS in planetary (crop) mode but was afraid of losing frames by not getting it centered enough.  Any time trying a new focal length on something it can be a learning experience. 

Oh, right.  Now I must be a true globe Earth shill.  lol waytogo.gif   Isn't it great to be capable of understanding simple geometry?  I can't imagine how hard life could be if I did not but it might explain some of the driving behavior I see. lol

Here is a redo of the animation using PIPP to stretch the image and create the .GIF file.
