summer milky way

Posted By John Beadles

This is my first film Milky Way image. Done on E200 film, 50mm lens, f/2.8, 10 minute exposure. Some glow from the horizon, but still turned out pretty good. 8)

University Optics mirrors

Posted By John Beadles

I have a UO 12.5" mirror. I also have an Orion 10" XT-10 and the 6" f/8 XT-6. I would just leave it alone if I was you. Orion optics are good for the money. Plus the fact an f/8 mirror is easier to make than an f/5, so the odds you have a major error in your primary is slim. UO / Discovery mirrors are nice. I doubt I'll be replacing mine with a Zambuto or Swayze anytime soon, although I do think about it now and then... 8)
