Touching the focuser moves the telescope (even a little bit) and with a relatively large Newtonian trying to focus can be a bit tricky. I have to say here that I absolutely love using a motor focus which gives an ability to move the focus position without touching the telescope. The focal length of my newtonian is 1200mm which gave a relatively nice magnification for viewing the moon. ![]() I used the QHY 5L-II Color camera, which has a color CMOS sensor of 1280×960 pixels. ![]() Telescope, mount and camera setup and pointing at the moon. When the moon is low in the horizon, below 30 degrees, usually we don’t get as good a view as we would get if it was high in the sky. The moon was relatively high around 55 degrees which is a good thing because it means that light coming form the moon has to pass less atmosphere (or “air”) which kind of disturb it. Luckily enough, my collimation was just fine so I did not need to re-align the telescope optics. All that detail, mountains, shadows, craters, it is just amazing to be able to look at this distant world, which is at the same time amazingly close to us considering the scale of the cosmos. No matter how many times I look at the moon I always get mesmerized. A couple of days ago I took my 8″ Newtonian out of the closet to get some fresh air and observe our beloved satellite, our moon.
