You can do a few things to try and fix a Celestron finderscope that is now working. First, check that the batteries are fresh and installed correctly. Next, check to see if the finderscope is properly aligned. If it is not, you will need to realign it. Finally, make sure that nothing is blocking the view through the finderscope.
A telescope is the best way to view distant objects in the sky, but you need a finderscope to help you aim your telescope. The finder scope is an important part of the telescope.
It is used to help you aim the telescope at an object you want to view. If your finderscope is not working, it can be frustrating. So, what can you do to fix this problem?
In this blog post, I will discuss seven of the most common ways to fix this issue. I will also provide some tips on how to prevent it from happening again in the future. Let’s get started.
13 Ways to Fix a Celestron Finderscope Not Working
Read on as I discuss the various ways to fix a Celestron finderscope that is not working.
Check The Batteries
The first thing you want to do when troubleshooting a Celestron finderscope is to check the batteries. If the batteries are dead, then the finderscope will not work.
Make sure that you have fresh batteries installed correctly. If they’re old or inserted incorrectly, they may not be providing enough power to the scope.
This is the most common reason why a finderscope will not work.
Check The Alignment
Another common issue is that the finderscope is not properly aligned. This can happen if you bump the telescope or the wind blows it off-kilter.
To fix this, you will need to realign the finderscope. This is a simple process that you can do yourself.
Check the Focus of the Finderscope
If the finderscope is out of focus, it will be difficult to see anything through it. You can fix this by adjusting the focus knob on the side of the scope.
Check For Blockages
Sometimes, the problem is not with the finderscope itself but with what is around it. Make sure no trees, buildings, or other objects block the view through the finderscope.
Also, check to see if anything is blocking the telescope’s eyepiece.
Clean the Lenses
Clean the lenses of both the telescope and the finderscope. Dust, dirt, and fingerprints can all interfere with the light passing through the lenses.
This will make it difficult to see through the scope.
Screw the Eyepiece of the Finderscope in Tight
Another common issue is that the eyepiece of the finderscope is not screwed in tight. This can cause light to leak out, making it difficult to see through the scope.
Make sure that the eyepiece is screwed in all the way.
Tighten All the Screws
Ensure that all the screws on the telescope and finderscope are tight. Loose screws can cause all sorts of problems, including making it difficult to see through the scope.
Check The Connections
Make sure that all connections between the telescope and the finderscope are secure. If any of them are loose, it could cause the finderscope to stop working.
Update The Firmware
You may need to update the firmware if you have a computerized telescope. This is software that controls how the telescope works.
Outdated firmware can cause various issues, including problems with the finderscope. You need to connect the telescope to a computer to update the firmware.
Try Using a Different Eyepiece
You can also try using a different eyepiece in the finderscope. The current eyepiece may be damaged more than you realise.
Swapping it out for a new one may fix the problem.
Collimate Your Telescope
Collimating is when you align all the lenses and mirrors in the telescope. Sometimes the finderscope may not work because it is not properly aligned.
This is a more advanced procedure, so you may need help from someone experienced in collimating telescopes.
Restart The Telescope
If you have tried all the above and the finderscope is still not working, try restarting the telescope. This will reset all the settings and may fix the problem.
Contact Celestron
This is the last resort, but if none of the above works, you will need to contact Celestron. They may be able to help you troubleshoot the problem, or they may need to repair or replace the finderscope.
Preventing Future Issues
Now that you know how to fix a Celestron finderscope, you can avoid having these issues in the future. Here are some tips:
Store the Telescope Safely
A telescope is a delicate instrument. It should be stored safely so it will not be bumped or knocked over. When traveling, ensure you have a secure case to protect it.
Check The Finderscope Regularly
It is a good idea to check the finderscope regularly to ensure it is still working properly. This way, you can catch any problems early on and fix them before they become serious.
Keep The Telescope Clean
Keeping the telescope clean is important for optimal performance. Dust, dirt, and fingerprints can all interfere with the light passing through the lenses.
This will make it difficult to see through the scope.
Update The Firmware Regularly
As mentioned earlier, you must update the firmware regularly to keep your telescope working properly. This is especially important if you have a computerized telescope.
Check Batteries
The major cause of finderscope problems is weak batteries. Check the batteries regularly to ensure they are still working properly.
If they are not, replace them as soon as possible.
Make Sure Screws are Tight
The last thing you want is for the finderscope to come loose while using it. Ensure that all screws are tightened properly so this does not happen.
