Found an old pic of my OTA with an eyepiece fiteed. Note the length of the extension I had to use on the focuser.

Johninderby out of curiosity what mount do you use? I'm looking to replace mine in near future.

I used it on a Skytee II alt az mount. Was too heavy really and needed a stronger mount. That”s why I sold it on as I didn’t want to spend the money on a stronger mount at the time.

Perhaps an EQ6 would be OK for visual use.

The weight is def a huge issue ldx75 mount is maxed almost to much with full set up

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.

 

First pic is what is in there now fully extended 

Second pic is the original focuser much longer it is beat up pretty good but I'm wondering if I should change it out to try since I do not have a extension for the on currently on there?

Thoughts or suggestions are greatly appreciated

If you have a barlow lens then you may be able to remove the lens element from it and use the body as an extender.

The image you posted of the eyepices shows a barlow lens....remove the lens and fix an eyepiece into it then place in the scopes focuser.

You just need an eyepiece extenstion tube like one of these. Does your focuser accept 2” eyepieces or just 1.25”.

Accepts 2" unfortunately where I live there is no where close to get one would have to order it

Hopefully will be just the right length but impossible to be 100% sure until you try the eyepiece with it. 🤞🏻

Be sure not to mark or damage the extender in any way while testing it in case you need to exchange it.

In that Celestron lens kit there is a Barlow lens. Its the one in the top right of the picture, If you unscrew the lens on that you can then use the tube as an extension.

Don't wait for darkness. try getting focus on a distant object in daylight, much less frustrating.

I'll take a guess that you mean the tube rings have broken? You may be able to find a way to fix it or alternatively buy a replacement pair of the correct size. If you have one good one left as a spare that's maybe no bad thing as you can mod it so the OTA remains in the correct balance point each time you re-mount it or while rotating it to get a better EP position. 

Can't comment on the focuser, but if you've found a way to get visual images into focus and do plan on trying photography, perhaps save the cost and stick with the one fitted, given the prev owner was using it for this purpose?

However, you might consider adding a counterweight so that the OTA is balanced with the weights further up the bar to reduce oscillation when imaging.

What was the solution by the way? might help others in the future...

I used a Skywatcher crayford which worked just fine and not too expensive. New mounting holes for the Skywatcher base plate will probably be needed and of course removing the corrector plate.
