Doesn't the optic head/objective just screw back in?
It might not be well collimated if the same position is not found.
An out of focus star should show serious misalignment.
David Hinds, Tring I think was a Celestron specialist but not all Celestrons were sold via his store.

It may be that Celestron don't have a U.K. service centre.
Maybe items are sent to Europe or the U.S.
East Coast binoculars might repair a Celestron scope.
It depends on the value of the scope as to whether repair is cost effective.
If it just need screwing back then any waterproofness is lost.

It may be that if Celestron do not have a repair centre in the U.K. their policy is just to replace any faulty scopes.
If this is the case, I think that filling in a repair document and mentioning that the scope fell apart might result in a new scope.
It may be cheaper for Celestron to replace rather than repair.
There is a Celestron telephone number in the U.S., which may result in a proper reply.

Thanks for the reply. Images are here. I purchase from F1 in Kent but they ceased trading during Covid. I don’t understand the mechanics so if it does screw in that would be great aside from feeling like an idiot. It literally came off as I unscrewed the cap. It’s a Regal M2 80. Decent scope for the price if you don’t mind the size.

Hi,
If the small particles are glass, then there is a problem.
If maybe some kind of glue, then one needs to carefully clean it may be using a small vacuum device with batteries to extract any remnants inside.
Then screw it back carefully after cleaning seeing how many start positions there are.
The scope is no longer waterproof if it was before.
Alternatively, if there is no glass damage, then ask East Coast binoculars whether he can repair it and purge it with nitrogen or argon or whatever is needed to make it waterproof.
Also, it may need realignment.
Maybe £100 cost?
So, are the small particles glass debris or something else?
I think you just applied too much force and should have held the top of the tube when unscrewing the cap.
I don't suppose you have house contents accidental damage insurance.
But even if you have there may be an excess.
So, ask East Coast Binoculars for a quote, and if he won't repair it, who might.
You could ask Richard at Action Optics, Southampton if he might have a go.

B.

thanks for the help. The particles are all some for, of adhesive. There’s no physical damage that I can see beyond the obvious. Certainly no broken glass. It works when popped back in, just doesn’t stick. I’ve been reluctant to mess with it out of fear of doing more harm. I have enquired with my insurers but until I get quotations for repair I need to weight it up against the excess. The Celestron customer care are still unresponsive.
Hi,
the notches in the eyepiece mount and the corrsponding protrusions in the body to prevent the mount from moving show that it was not screwed in. My money would be a failed glued connection and I would remove the old glue and find some new fitting the materials to connect - certainly plastic for the body and maybe metal for the EP mount?
As for nitrogen - you only lost 22% of the 100% nitrogen filling... if it was actually kept in by the glue joint - there could also be a protective glass in front of the prism assembly still keeping it in... in that case there is probably no glass in the eyepice mount when taking out the EP.

It is good there is no broken glass.
Orion Optics UK say they will service and repair any telescope.
They make telescopes and have coating facilities with a complete workshop.
Beacon Hill also can repair scopes if they are still active.
Then there is Richard of Action Optics, Southampton, and East Coast Binoculars.
Also the very good repairer on the south coast near Selsey.
Personally, I would carefully remove all the particles with tweezers and possibly the tiny vacuum I have for small jobs.
I would try not to move the prisms at all..
Then screw the objective tube back in tight but not too tight.
I would see if there was more than one thread start.
With a bit of luck the alignment would still be quite good for normal observation.
But maybe not waterproof any more.
If I got a good alignment using out of focus stars I would mark both sides of the joint for future reference.
Depending on the work time needed I suppose a professional repair might be £100 to £150 including alignment and sealing to make waterproof again.
I have collimated refractors from the objective end, but not spotting scope prisms.
I have also collimated Newtonians and Maksutovs etc.
But not binoculars, except for simple repairs.

To be honest I think I’ll go to someone who knows what they are doing. I’ve contacted east coast as I‘ve used them before. Rother contacted Celestron who apparently said a replacement is the only option based upon the same images I posted here, I tried fitting it back in but it seems the thread on the scope body is just shot. I’m no longer in Kent, now East Yorkshire.
Would either of you be able to suggest a type of glue? All of the repairs contacted have said no. When I place the eyepiece back in situ it works fine, zooms well and is clear. It seems the adhesive has failed and the thread possibly. I’m still waiting to hear from Celestron but if it is a write off then I’m inclined to have a stab at using an adhesive.
If it is insured then it is probably worth claiming, but I am not sure if the insurer requires the return of the scope.
You can tell them it is a write off.
However, don't allow them to use their own repairer.
I dropped a Minolta SRT 101 16ft onto concrete photgraphing comet Kohoutek.
The tripod and camera toppled out of the window.
It took a year for their lousy repairer, and then Minolta when I told them that their repairer didn't have a clue.
I immediately had bought a replacement camera after the accident.
I don't think I used the properly repaired camera by Minolta afterwards.
It had quite a different serial number as top plates of repaired cameras have special numbers.
If Orion telescopes UK of Stafford won't repair it, then yes have a go yourself.
I don't know what adhesive to.use.
It seems that Nikon 50ED and maybe Pentax scopes fail in the same place as the Celestron.
Nikon 50 ED repairers can probably tell you what adhesive they used.

Perhaps ring Araldite and ask their advice if nobody here gives advice.
Personally, I would try to make sure the two halves were well aligned and I would use an artificial star, i.e a ball bearing or spherical bauble and reflected sunlight at say 30m.
The out of focus star should have concentric rings with a central point.
Slight misalignment is probably inevitable, but should not have much effect on the image.
Hopefully, the prisms have not moved when trying to clear out the debris.
I am not sure if an alternative is to attach both halves to a plate to secure them in position.

Just a quick update. Celestrons customer service was poor on the communication front, all done via an online ticket system based in the USA but I ended up being asked to post the scope to their UK centre. Had no idea what was going on but today a Sony new scope arrived so credit where its due.

Interesting, where was there Uk Centre please?
