ngc3031 Posted March 31, 2017 Share Posted March 31, 2017 Had a very good ISS pass a few days ago. 200/1200 dobson ZWO ASI 290MC with a 2.5x Powermate (imaging camera) ZWO ASI 1600MM (guide camera) 400 gain 1.1 msec exposure Recorded at 160 fps The ZWO 1600 was attached to the finder scope of the dob. Combined with a tablet fixed to the telescope I could manually track the entire pass standing upright, looking at the tablet screen instead of through the finder scope. This allowed for much smoother tracking, escpecially towards the zenith. Out of roughly 80.000 frames 1300 contained the ISS. The gif consists of 70 images captured near the zenith. The frames are clearly overexposed, gonna have to reduce exposure time next time. Overall I'm quite happy with how this turned out. Link to comment Share on other sites More sharing options...
tooth_dr Posted March 31, 2017 Share Posted March 31, 2017 I'd love to capture this. Great images. Any photos of your setup? Link to comment Share on other sites More sharing options...
CraigT82 Posted March 31, 2017 Share Posted March 31, 2017 Very nice! I'm planning on trying something like this myself with my mak, your info on gain and exposure will come in very handy so thanks very much! Link to comment Share on other sites More sharing options...
ngc3031 Posted March 31, 2017 Author Share Posted March 31, 2017 As for exposure settings, take these with a grain of salt. I had to use very different exposure settings on my 750d (1/600 sec and gain 3200) to achieve similar results. Link to comment Share on other sites More sharing options...
Pondus Posted March 31, 2017 Share Posted March 31, 2017 Very Nice indeed. I managed to manually track ISS With an 8" dob, for maybe 30-40 secs. Not at all easy even With low Power. Rune Link to comment Share on other sites More sharing options...
