Hi Jeremy, thank you for the PM, I bought my scope in South Africa through an authorized Celestron dealer. I found my invoice so should be good there. I’ll need to check my paperwork and take it from there. Cheers again for the advice

Hi Alex, you are a genius! The chip is exactly where the screw for the finder scope bracket is!! Funny, I have been using the same screw for years. As soon as I started to loosen the screw I could hear the contact with the mirror, I stopped immediately.....Man this is turning into a nightmare, going to have to ever so gently unscrew and hope and pray for the best.

Just remember do NOT take the first NO for an answer and check out their laws on what i Pm'd you about

Send ALL communications registered and COPY what they send back

Finally (trust me) any phone conversations, record them

You are best to seek professional advice from an authorised dealer.
Too many people don't know that and assume they can just replace a mirror or corrector plate

Point a flashlight down the tube, move the mirror away from the screw, then remove the screw. To move the mirror towards the back of the tube turn the focuser clockwise.

NOT before he checks the GUARANTEE he has or taking any advice about paint, stickers, moving mirrors could VOID his guarantee

Jeremy, there's no warranty on 8 year old scopes damaged by user error.

I didn't know the age how did you

Are you assuming or do you KNOW it is "damaged by user error"

What Tony says is correct, the scope was bought in Dec 2009 and from the looks of it, a combination of me screwing in the screw of the finder bracket to far and then turning the focus knob to far caused the issue. My own stupidity!

While people usually figure it out before damage occurs, it's a fairly common occurrence seen from time to time on the forums, so don't feel too bad

Mark, what Tony is REALLY saying is, "gee, you're dumb!"

Eh, Tony...

Nice, thanks guys
Going to have to wait now for some time to tackle the mirror, I think I need to set aside a decent amount of time to remove the corrector plate and take out the glass shards and then test to check the diffraction and take it from there, I.e. to cover the chip or not.
Thanks again for everyone’s input and advice, I really appreciate it.

Hi everyone, thought I would post an update on where I’m at. I claimed through insurance and after quite a bit of back and forth they have agreed to pay me out for my scope, good news. I’ve had to return the scope, mount the whole caboodle to them before they pay the claim.

Question is what do I do, replace with another Nexstar 8SE which I have really enjoyed or move onto a dob, I’ve had my eye on a 10” GoTo skywatcher. Any thoughts or advice? I’m in two minds at the moment.

Cheers

THAT is exactly why I have always had new for old insurance all my life

My Father was an insurance consultant and always said to people asking why they needed insurance "Insurance is an un-rewarding expense until you need it"
