![]() Recently, I made another secondary housing which will allow me to use either the secondary mirror and eyepiece focuser or remove the mirror and mount a webcam or other sensor at the prime focus. drive and embellished the mount with stars and stuff I cut out of Alum. The images of the 12 1/2″ are somewhat dated. Like many of us, monetary considerations have slowed progress for this scope – I need to get the mirror coated. ![]() This last one is to be my ‘baby’ (I hope) when completed. mount and modified to look at sunspots using a projection technique and I am _still_ building a handmade 12 1/2″ Newtonian. I have a 4″ Meade Schmidt Cassegrain model 2040, a Kueffel and Esser (sp?) 60 mm refractor that I have mounted on a German Eq. That’s a 1 followed by twenty-four Planemo… Hello! I own three scopes. There are spiral galaxies out there with more than a trillion stars, and giant elliptical galaxies with 100 trillion stars.Īnd there are tiny dwarf galaxies with a fraction of our number of stars.Īccording to astronomers, there are probably more than 170 billion galaxies in the observable Universe, stretching out into a region of space 13.8 billion light-years away from us in all directions.Īnd so, if you multiply the number of stars in our galaxy by the number of galaxies in the Universe, you get approximately 10 24 stars. These massive structures can contain more or less stars than our own Milky Way. The vast majority of stars in the Milky Way are red dwarf stars dim, low mass, with a fraction of the brightness of our Sun.Īs we peer through our telescopes, we can see fuzzy patches in the sky which astronomers now know are other galaxies like our Milky Way. Many more are average-sized stars like our Sun. A few are supergiants, like Betelgeuse or Rigel.
