Correction these were shot without powermate at f/10. Today I tried the powermate on the #ISS but (as with earlier barlow experiments) there seems to be not much benefit because the higher resolution comes at the cost of longer exposures which increase motion blur.
Quick view of this evening's #Jupiter. 1000 x 10 ms unfiltered mono in Celestron 8" + 2.5x powermate.
@latuernich I feel old now realizing how long I've been doing this but here is an image I tried 2014 of the automated transfer vehicle that is about 10m long so large enough to show a bit of structure but well you see...
@latuernich technically yes in the sense that it may resolve to more than one pixel but it is unlikey to show useful detail. ISS is about 100m from end to end so you can see useful resolution here is about 1m/pixel.
Two views of this evening's #ISS pass over The Hague. 44 / 14 x 0.2 ms unfiltered mono in Celestron 8" + 2.5x powermate. #astrophotography
This evening's two day old #Moon crescent 3.8% illuminated. Single shots 1 sec and 15 sec EOS 400D in Celestron 8" + 0.63x reducer. #astrophotography
If you look carefully at the great red spot you can see that it appears to move a bit faster than the dark structures to the south this is due to differential rotation.
Time lapse of #Jupiter Wednesday night covering two hours of real time. 60 x 3000 x 12 ms RGB in Celestron 8" + 2.5x powermate. #astrophotography
Longer exposure of #Saturn reveals some of the moons.
70 x 2 sec Ha 35 nm in Celestron 8" at f/10 (oops I forgot to remove the filter which is silly when going for faint objects)
