Hi Yohanan, Don't know your interest in exploring the night sky, so a few questions. If you are really interested you might look into joining a local astronomy club. Your scope sounds like a 90mm aperture Mak or Cassagrain scope model. Sounds like the lenses you refer to are actually called eyepieces or oculars. Have you tried you scope from a dark sky location where the Milky Way would be visible? There are lots of deep sky objects that should be visible in your scope. If you have some kind of night sky atlas and learn to navigate the night sky to find some of the brighter deep sky objects you can find these objects. Also, Venus, Saturn, and Jupiter are all in the southwestern sky now lined up in a row and are bright enough to be easily identified and should show easily in your scope. Saturn and Jupiter are my favorites. I have three reflecting telescopes, aka Newtonians, one with a 12.5 inch diameter primary mirror and 2 other reflecting telescopes both with 10 inch mirrors. I have a favorite saying: If you want theories and facts, look to science: but if you want truth, look to the Bible. God can and has used events in the night sky like comets, novae and supernovae as signs that we can identify and understand. I have a lot of light pollution here but could get up the the north Georgia mountains easy enough. Next time I’m up that way I’ll take the scope with me. I have Night Sky app so I should be able to get in the right direction. Yes, there is a local astronomy club here but I’m not sure I have the time to join. They might have viewing event open to non members. I watched some videos on Mira. It's a truly amazing star. Thanks for the heads up. It's going to be so fun exploring the universe in eternity. We can all be astronomers. :good:
