>>2578990>>2579003thanks! This is actually my 2nd attempt. My first one was the same setup (127/1500mm Cassegrain and EOS1100D) but my exposure time was too long. I did my focus on the planet Venus (someone on a forum said it was the same magnitude than the ISS), but all I could see on my shots was a bright sphere. With shorter exposure it was fine.
I will try again with a barlow lens (3x focal length) but it will make the ISS really really hard to track. and damn this thing is moving fast.
bump with M81 and M82 galaxies. (1000mm Newtonian telescope). already posted it in the old astro thread but the weather is shit and I have nothing new :')
