  1. Focal ratio is governed by focal length divided by aperture end of.. so that's why f5 scopes don't have the same fov if either the fl or the aperture is different.. focal length gives you big the target will be, the aperture gives you the brightness as more photons are captured, if your imaging circle is bigger it can illuminate a bigger sensor.. Thought it was about microlensing anyway
  2. Still quoting in f ratio, f8 is the focal ratio..you said f8 focal length?? And the add a Barlow to make it f15 focal length??? Full frame sensor will have a wider fov than a 1600 Your c11 edge will have a reducer to make it f7? I personally feel if you scope has a bigger imaging circle the bigger the pixels you can use..
  3. I see that as a halo, not microlensing.. Are you using more than 1 filter ie a light pollution filter, is your filter as close to the sensor as it can be?
  4. I don't see f ratio as fast or slow, I see it as wider fov But since you ask , yes a f5 frac was the last one I see
  5. First thing I do is zoom in..never seen blocky stars at my own 3.0 pp.. but then again I'm never going to get it printed A4/3 size..
  6. Great job lee,enjoy the camera and keep those images coming
  7. Yes I agree with you Olly, I'm continuing to hear that you can't undersample as you get blocky stars..when I show them your image of the witches head at 3.5 pp it all goes strangely quiet.. Then they say it again a few weeks later!!

  9. Good ol windows.. Glad you got it connected but when imaging turn off the internet connection to the internet as you say I'm sure they watch you and then try to mess up your eve with a update
  10. Not sure that's the way, I've seen plenty of images with small aperture and focal length scopes with micro lensing effect..
  11. If it helps..I have the shaped packaging which is what I store my c8 in..don't mind it being borrowed to send the scope in as long as it gets posted back
  12. You could send it to me for a few months of thorough testing....!!
  13. What camera is it, obviously a atik? Driver issues..Windows is fantastic for that..
