A regular problem with this red dot finder, is that once some users have changed the battery, they can not get the new one to work. This short video shows what may have caused the issue, followed hopefully by a solution.
OK this may not work for everyone and all situations, but costs nothing to try.
Thank for watching.
Thank you very much! I was prepared to completely disassemble the finder and the solution was just this simple.
Glad to be of help, and thank you for watching our channel
For me the problem was in the knob that adjusted the intensity of the red dot. It had a loose connection. On pressing the knob tightly on its side, it worked. Hope this too helps.
Nice that you provide support... Wish I bought through you. I just got a 102 and turns out the focal knobs will NOT move my eyepiece in and out of main tube. Celestron's support, NOT GREAT, told me it was "stuck" and to back the screws off and "pull the tube apart." So I did that. No deal. Ever see those knobs not responding, and not sliding the eyepiece such that you can focus?
In my issues it was related to the on-off knob / intensity settings. A tiny Philips screw at the on/off knob needs to be readjusted after so many uses. I exhausted battery issues to no avail. Try in a dark space to observe if a red glow, it leads to premature battery failure . Switch failure due to screw tension has many variables.
You think that's bad? I can't even mount my finderscope because the base of it is missing 2 holes to mount it! Waiting to hear back from Celestron support for the Starsense Explorer LT 70AZ and why they gave us the wrong base inside the box for the finderscope.
I bought mine second-hand, and the manual doesn't mention how to change it. I'm glad i found your video, and only 2 weeks after you posted it, too!
Result ! . Thank you for watching our channel
Can you tell me the battery specification?
I have added a thin disk of foam packing inside the battery cover. This presses the contact down on the battery to ensure a good connection. I feel that this is something they should include from the factory.
Great tip, and thank you for watching our channel. Wishing you clear skies.
This was helpful but still didn't work for me. After looking at it and moving alignments around I noticed you can see into near where the potentiometer power switch is. So I cleaned it out by blowing into that to get any dust build up off the switch contact. I also wiped off the glass where the led is. After that I noticed the light flickering which was some sign of function. So I blew into it some more to get any further dust out and now it's working. Hope this helps.
Excellent result. Thank you for sharing
Thanks, i needed to do the battery thingy and i just cleaned the glass and the laser and took the potentiometer cover off and cleaned it. Save myself 20 quid.
Thank you! It took me a minute to figure out how to remove the plastic battery cover without breaking it. It simply pulls off and pushes back in. Easy peazy!
Wow i can finally see the red dot. After searching and searching videos, this was the solution. A loose battery😞
Thank you for this. Fixed the rattling battery. Still stuck though. Just feels like such a cheap bit to be stuck on the side of a telescope.
I have the battery the right way, the metal tongue holds it firmly in place. I still don't see any light, I don't even know what to look for as this is my very first time and I am stuck trying to make the pointer thingy work
There is a chance it could be faulty. If bought new contact the retailer for advice.
Had some viewers contact us to imply the RDF in the video is not a Celestron one. This particular one was taken off a Celestron Astromaster 80 EQ MD . Yes this type of mass produced product, is re-branded in many brand names. But this one was definitely out a Celestron box. So yes, this video applies to many other same / similar RDFs.
I was putting it upside down. Thank you
Ótima dica, eu pensei que tinha quebrado o meu. Fui lá e fiz oq que mostrou e pegou 🙌🏻
Bottom line this finderscope is cheaply made. Already sent a message to Celestron to fix the problem. After spending what I did on this scope, there should be better quality. Total BS!!
I have noticed with the odd batch, Skywatcher have included a little more beefy RDF. Maybe they are trying out different ones. On the 2-3 occasions our customers have said the Celestron RDF wont work, I have tested and sent another out , no questions asked. Wishing you clear skies.
What battery does it take?? Nobody mentioned it!
CR2032 3v as mentioned already in one of the comment replies
Celestron should be ashamed for putting these on their scopes… they are useless junk. The one that came on my scope failed after 2 days( not a battery issue) the replacement they sent didn’t work at all right out of the box( again… no a battery issue) finally the third one actually turns on and works…. But … can’t get it to align properly, not enough travel in the vertical adjustment 😖😖😖 the best fix is to take it off your scope and throw it in the garbage can!!! Going to adapt a green laser for a finder 👍👍
Once when experimenting, I found I could fit a weaver mount red dot sight on a celestron RDF bracket with a little persuasion . Not sure if all weaver mounts are the same size
My on and off switch doesn't click anymore, and the red dot won't turn on, I tried the solution in this video but it didnt work, what should I do?
If it is under warranty contact the retailer for advice. If not, there is somewhere a video tutorial on how to strip them down on you-tube. Otherwise its a case of getting another
We're can you get that battery please tell me
Look on eBay or in your local shops for CR2032 batteries. Thanks for watching our channel
I changed the battery but it still wont work. Is there another problem with these scopes?
The switch. Try a little tap on the switch wheel. This finderscope is pretty awful. All is plastic. I have tried to change for other of metal. Even other brand, but I think is no to easy for the holes on the base. If anyone has the answer please let me know !. Thanks.
@@fugomaye396 it actually worked. Thank you.
Top marks to you. As per DankSter420 , I found a little tap got a RDF working again, I thought I could not fix. Not perfect, and may need the odd further taps to bring it back into life. Was a spare RDF I was using for demos. Great to get so much user feed back on this topic
@@fugomaye396 Thank you for the tip worked for me too!
@@fugomaye396 Man, mine was dead. I just did what you said, changed the battery and kind of slapped a few times, back from the dead. Thanks a lot
Would this item fit onto a DSLR Hotshoe mount ?
Been asked this a few times. Simple answer, no . Thanks for watching our channel anyway.
How do you even turn it on?
Look at the thumbnail photo. The dial to the left of the sheep hand as we look.
Thank you!!
What battery?
CR2032 . Thx for watching
Can anyone tell me what battery size ?
CR2032 3v
Thanks thanks thanks alot
Tried this method but no success. Gonna open it up and test the potentiometer and led.
Brendan would you please share the circuitry with me if you happen to know how it looks inside properly wired?
My battery was in upside down right out of the box. Also, it was only in the comment section that I saw it has and on/off/dimmer switch.
The battery bit is the easy bit ... I need to know how to take the cover off without breaking it 🤔
Careful prising force from all 4 sides with small amounts of pressure . Very steady as she goes. Its one of those things where patience is a virtue
There is one prong at the front and two at the back. Taking out the front prong is easy. Gently lift out the back prongs by lifting up the sides and the back. Reading/watching other sources of info led me to believe I just needed to force up the front, but that would have snapped the back prongs!
obviously very poorly designed battery lid.
From many years of selling and servicing telescope parts, it one of the best designs. Clips securely in place. The last thing you want is a cover that comes off too easy , drops off and gets lost. Its a much better design than the celestron starpointer Pro, which can be easy to strip the threads + the coin slot for unscrewing is easily damaged if care is not taken.
@@44messier - fair enough. The problem is probably me -I only rarely need to change the battery so I forget how to do it nex ttime (and it looks, misleadingly, as though the cover should just flip up, but is being prevented by the dovetail behind it). Andt here's nothing in the Celestron manual.
Thanks
No problem
My problem is that the battery keeps dying even when switched off. I'll replace it one night, turn it off and next day I need to replace it once again. I think the switch must be faulty, and doesn't properly break the circuit.
Not exactly a couple of solutions, but nevertheless useful.
Glad to hear I am useful for something ;-) . Thank you for watching our channel.
This actual help me as well :) Thanks
Fred, this man owes you nothing bud.. Helped me too.
That's all well and good for this pointer however the one I have which is very similar so similar in fact I thought it was the same one until he turned it over and there the battery was in a spot where a blind person could change it. My battery is buried inside the plastic housing with no possible way to get it out without breaking the damn thing.
If it is buried deep inside, it must be a different design / brand.
Thank you man 🫶🏻
Happy to help
