Query re Eyepiece view from a Dobsonian

Recommended Posts

Hello everyone 

I've just bought my first telescope, a 10 inch Dobsonian, Saxon brand (same as Skywatcher).

In daylight I've collimated it with a laser collimator.  Also in delight I've centred the finderscope on a house on the horizon (probably 5 km away). The image is inverted and the left side appears on the right.  I understand that's normal.

The house is also centred in the eyepiece and the view is inverted and left appears right, as with the finder scope.  BUT the horizon is at about a 60 degree angle ( see pdf sketch attached).  Is this normal? Or am I doing something wrong?  Or is there a problem with the telescope?

 

Many thanks in advance

 

Susan

As above. That's normal for a dob.

Congratulations on the new scope and welcome to the forum :smiley:

      Hi, i have made a video where i show a coople of eyepieces that i use and like, and also show how a barlow works, compared to the "Powermate" from Televue. And how is the FOV affected when changing the magnification with different eyepieces?

      Feel free to comment and give me feedback - I hope you like the video!

      I am looking for a Vixen HR 3.4mm eyepiece. I have a 2.4 and it is great on a good night, but usually a bit too much power for my FLT132.
      Is there a chance you have one that you don't use?
       
      Thanks for looking

      Gt my telescope based on recommendations here years ago. Its getting dusty though.
      Really just want to see as many planets in solar system as possible please. I read plenty but its too much to remember sorry. Struggled just looking at the moon
      Most things said barlows are a stepping stone.
      Can someone point out an eye piece on first light optics or something similar in UK please. Its for me and my 6 year old space obsessed son.
      Also a polarising filter if there worth it. Is a collimater cap as easy as a laser? I wont get round to making one so ill buy.
      Last step would then be plumbers tape on the eyepiece threads right?
      Thanks

      Hello, I am having a problem with a relatively expensive flat field eyepiece in a combination with a newtonian reflector. I am unable to achieve proper focus with that eyepiece because when I focus it on axis, the edges are blurry. When I focus it at the edge, the center field is out of focus. I don't want to mention the concrete type of this eyepiece because I received it with a spot on the bottom barrel, therefore I cannot be sure whether it has been dropped. This eyepiece has very good reviews on this forum. Optically it looks good and there is no rattle. My question is whether these flat field eyepieces are usable with newtonians as these telescopes doesn't generally suffer from the field curvature. Many thanks for help.
