I know it sounds crazy, but is it possible to connect a reflector telescope and a refractor telescopes (like monocular for bird watching) together to build a better telescope?

  • $\begingroup$ It's not clear what you're asking. Are you looking to build a binocular telescope from two different telescopes? BTW, almost all telescopes are "monocular" - perhaps the other scope is actually a refractor? $\endgroup$ – Florin Andrei Feb 7 '18 at 20:31
  • $\begingroup$ Yes, the 2nd one is refractor telescope. $\endgroup$ – notilas Feb 7 '18 at 20:38
  • $\begingroup$ It's going to be difficult, and it will not work very well if the telescopes differ in any significant way. If you want to use both eyes, consider using a binoviewer adapter instead (looks like the rear part of binoculars, has two eyepieces, plugs into the focuser of a regular monocular telescope). But do some research beforehand, because these are not necessarily plug and play either - there might be requirements of backfocus, etc. $\endgroup$ – Florin Andrei Feb 7 '18 at 20:48
  • $\begingroup$ You want a serial connection of the two? Then your main optical properties (image resolution, light collecting area) will be dominated by the first one simply, and the whole exercise is naught. $\endgroup$ – AtmosphericPrisonEscape Feb 7 '18 at 23:24
  • $\begingroup$ Finder scopes work. You're talking serious cash to match your 8" reflector with an 8" short focus refractor. $\endgroup$ – Wayfaring Stranger Feb 8 '18 at 16:03
