Please help. Celestron NPF 60 travel scope - blurry image

Recommended Posts

Hey guys I'm new to telescopes and well I have tried reading up on possible fixes, nothing works. 

First day I used it I was able to get a clear image on the lowest power inserting a 20mm eye piece and it would focus. 

Attempted my first night to look at Mars. Well it was a big blur and nothing worked. 

Next day I was attempting to look at a mountain and no matter what I did or try it remained blurry. Focus dial is free moving but the image stay as a massive blur. With no eyepiece it's still all a blur. If I look through it backwards there is a clear image however looking from the eyepiece it remains blurry. 

Im not sure what to do now. Any ideas?

What kind of telescope are you using? Some scopes are more sensitive to internal heat than others, so that may be playing a part. Also, Mars can be a really awkward customer. It's a tiny world with a brilliant disk, so to dull the image, especially in a large aperture scope, its best to use a reasonably high magnification. However, increasing the magnification also increases the visible effects of atmospheric turbulence, which will wash out any detail. 

You mention that "the image stays as a massive blur!" That sounds to me like the telescope isn't properly in focus. Does the mountain you tried to focus on appear to come close to being focussed? If you're using a Schmidt or Maksutov Cassegrain you may have been turning the focuser in the wrong direction. It might be a good idea to look for a local astro society near by that could take a look and who would be more than happy to help you out.

The focus wheel may be turning but is the focuser actually moving in and out as you turn the wheel ?

Are you using a Barlow lens in the system too? With a 20mm eyepiece Mars will will be small, not massive. I kNow some lower end scopes come with a 3 x Barlow, or possibly a 2x Barlow, so if you are using one of these along with the EP then take the Barlow out and just put the EP in the focuser to view with.

Shaun has hit upon the likely culprit. So I've gone and pulled-up some pictures of you National Parks edition Celestron. Underneath the focuser should be a metal-knob, a small bolt actually. Tighten this up and then turn the two focus-knobs - one on each side of the draw-tube the diagonal (what you put the eyepiece in so you don't need yoga to look into it). You should see the focuser move in & out as you turn the focus-knob.

If it doesn't, try turning the small-bolt the opposite direction. Once you've got the focuser moving in & out, try an eyepiece and attempt to focus on a distant object - in daylight again. Once you have this down, onwards to the stars!

Let us know how you're doing, please.

Enjoy -

Dave

when I try to adjust the focus the telescope focuser will adjust however the image I see remain a blur with no change at all. Also the first day I used it the image was projected normally but now it is inverted and doesn't seem to adjust.  Anything from 100 meters to .5 miles away. The telescope I got is a clestron national parks foundation 60 travel scope. Meant for camping and day hikes I loved the concept. I tried to carefully adjust one of the lenses to see if that would do anything but to no prevail.

If the image was the right way up but now inverted then something must have changed. Are you using the supplied erect image diagonal, which will give a right way up image.

It can only be one of a few issues all of which have been mentioned above, the last being as Peter mentioned above IE the diagonal not seating correctly or the mirrors are not clean....... This may make give the effect of looking clear one way as the view would be so small you do not notice the blur when looking through it in reverse.

Not sure what the problem is but its one of the above most likely. I have a 70mm Celestron travel scope and one thing i found out very quickly is that it doesnt do well at all when trying to observe planets. It, like your scope is designed as a wide field scope which is good for looking at star clusters and that sort of thing. It should give good views of the Moon also. It just cant handle the magnification needed to observe planets. 

A better tripod helps a bit.

Ok I am not sure how weird this is. But the national park foundation celestron 60 Travelscope is only focusing with the angle lensepiece (in picture) after pure frustration. I went back to what I could remember worked. And well I guess I'll always need the angle lense. Is this a common thing? Anyways I really do appreciate all the help and feedback.

It's possible it needs that travel and distance to come to focus. So that may be a 'yes' to your question. However as it's a 45° diagonal, it isn't the best for observing objects in outer-space like stars & planets. 45° diagonals are generally used for terrestrial observations. A 90° diagonal are considered best for the purposes of astronomy.

I hope this helps,

Dave

      Hi I am fairly new with telescopes and I noticed my telescope needed collimation. I preview the collimation at the beginning (tell me please if its alright) however after I finished the secondary mirror kept tilting and not staying in place as seen in the video. This is a Heritage 130P telescope. Please help.

      Hi everyone!
      As I said few days ago in my presentation I recently got my first scope  (skywatcher 127) and over the last days I tried to test It.
      Due to impossibility (temporary) to bring the scope in a decent location to make observations, I had to test it from home through a window  (and under the sky of London - not the best at all). So i know that quality is of course affected.
      On the other hand, I am sure that the performances are worse than I could expect also under these conditions (maybe you will correct me) and would asks for opinions to improve.
      As a (mainly) planetary scope, I did not have a lot of choice: no Moon, Jupiter and Saturn out of my field of view. I pointed at Mars.
      First sight, I see the very big central obstruction. I played with the knob of the focus to get rid of the big black spot in the centre of my target and here you are the issues that I would like to talk about:
      1) the target became very small (ok) but still was not focus  (very blurry and not a lot of clues to get atleast the shape of the planet well defined - can imagine to find any detail on it )
      2) Also the colours did not convince me as no other colour than a light yellow was visible
      3) Changing the eyepiece  (10 instead of 25) for a magnification of 150x did not improve the situation: probably the image was even worse, more blurry with more irregular shape than before, no ability to focus at all. Differences from before : bigger (but still much smaller than expected) and very little variation in colours (I believe I saw a bit of orange).
      To complete, later, I tried the scope to stars: Orion costellation was visible from my place and tried to all the stars. Although still a bit blurry  (the brightest stars), I had impression of more sharp view, differentiation in colour and better shape  (stars almost like a dot). Moreover, to give you a final idea, Mars (at the best focus I could get) did not appear that much bigger than Betelguese.
      What do you think I can do to get better results? Could be a scope problem or some adjustments needed? Unfortunately I have no comparisons. 
      Thank you, Hope I was not too long 😅

      Hi,
      I am hoping someone here may be able to offer some help or advice. I have submitted a support ticket with Celestron but I am still waiting for a reply and would really like to get this working ready for the next clear sky!
      I recently brought a starsense but have not been able to use it because it comes up with the following errors,
      Err: Model Num
      The telescope model could not be read and initialization cannot proceed.
      Critical error!
      File: ..\source\mo
      Line: 1468
      An unexpected error occurred that may cause the HC to not opperate normally.
      When updating the controller and camera it finishes succesfully but when I check for new updates it proceeds to install the same one again and again.
      I can still control the mount and I think the camera tried to do an alignment in my room.
      I have a Celestron Nexstar 6SE.
      Thanks

      Hello all,
      I always been fascinated by astronomy and finally purchased a celestron nexstar 8se. Setup went smoothly but I'm a little stuck on the lens. I attached the star diagonal to the telescope and focused in on an object. I was able to see a part of the leaf on the plant in my house and I attached a picture of that. Moving the telescope left and right allowed me to see other things. I then took out the 25mm lens and can see through that when not attached to the telescope. I can see my sandals and feet through the lens and attached a picture of that. I then inserted the 25mm lens into the star diagonal and that's where all hope gets lost. I see white (assuming that's my wall) and yes the cover on the telescope is also off. No matter where I move the telescope. All I see is white. I tried last night in clear skies and pointed towards some clear stars using the skyportal app to align but I didnt see anything except pitch black through the lens. I also played with the focus but nothing. Am I doing something wrong, I would think the 25mm wouldnt be so zoomed in that I cant see anything? Thanks for any help you can provide me. Looking forward to exploring!!
