Re: Milky Way and M83 with iPhone

hi thanks. The noise level is low enough to see galaxies. There is some walking noise and i wonder what causes it. How do you measure it? So far the app can image m31, m83, ngc 6774 etc. Here is an updated post at https://www.cloudynights.com/topic/657529-introducing-spiralcam/ Best regards

Re: Milky Way with iPhone

I wonder why an 6 inch dob needs to be heavy like 18kg. The mirror is only about 1kg. I am thinking of building ...
