To try and narrow down the problem wind the focuser in and out with nothing in it to check it's actually moving then wind it right in, have you got a longer focal length eyepiece ? something like a 26mm, drop in in the fully in focuser aimed at the edge off the Moon and then slowly withdraw it with your hand and see if the image appears to get less or more blurry, if it gets less blurry as you withdraw it but falls out before reaching focus there may be some sort of extension with it.

Using a camera would put the focus point in a different place to an eyepiece, some folk modify these scopes for imaging by moving the mirror up the tube which may move it too far out for an eyepiece.

Dave thank you for the ideas I will test these out and see...I've had this for over 5 months now and have been unable to get it to work...all these ideas are amazing and hopefully I will be able to learn help others at some point!

Hi again @Andy55

Upon a closer look at the second image, I think you have a type of single-speed Crayford focusser. 

As previously mentioned, I think the black thumbscrew adjusts the tension of the drawtube. If you cannot see the drawtube move up/down, then you will need to turn the thumbscrew a few turns until it does. Once you see it move, then tighten to a position where you think it is comfortable and will not slip.

 

So I'm pretty sure it functions properly the tube moves up and down freely and if I turn the screw it will lock it into position...previous owner did only use this scope for astrophotography I cant thank you enough for this advise unfortunately I'm at work this evening and will not be able to test these suggestions until tommorow...hopefully I'm understanding the function of the focuser it is only on component that moves correct?

Used to have one although fitted with a new Crayford and it focused with no problems.🤔

 

Never heard of that scope will have to look very nice

Hi @Andy55 and welcome to SGL. 

Couple of things spring to mind...

1. being a Schmitt/Newtoinan it may have dew forming on the corrector plate. - do you have dew-shield?
2. do you notice any change of the shape of what you are seeing? - you may need to keep turning the focus knob anti-clockwise or clockwise [in/out] before the object comes into focus. 
3. what type of focusser is it? - i.e. rack & pinion or Crayford? - looking at your image, I am thinking the black thumbscrew under the the focusser may be an adjuster to adjust the friction of the drawtube - can you turn it? 
4. what eyepieces do you have?
5. it maybe out of collimation, so will need to be collimated.

 

1.I have a dew heater no shield

2.no shape change I've seen 

3.rack and pinion (will add photo)

4. I have a 9mm and celestron kit very low quality kit but was told it will work 

5.collimation seems ok but I might have done it wrong 

I will admit I became over excited and purchased this scope with very little to no experience but I am baffled as to why nothing comes into view moon is just a bright blur and any other planet just looks like a black spot previous owner showed me amazing pics with this scope

Hi Dave 

I will send a pic as soon as I figure it out lol telling me file is to big 

Meade ldx75...schmidt newtonian 10 inch

I bought a meade 10 inch scope with the ldx75 stand I have been unable to figure out autostar...besides that I have not been able to get anything to focus at all not even the moon have tried every lense I have but nothing just a blur
