02:14 - the best video tutorial about calibrating the polarfinder I could find. Your pencil drawings are very helpful - they demonstrate the challenge as well as the procedure in a clean and simple manner. Most helpful for me was the part starting around 03:25 - the first and only explanation I could find of how the 3 screws must be used to correct a misalignment. Great thanks!
Your directions and sketch are one of the best I've seen that explain how to do this in terms that most anybody can understand. Thanks & keep up the good work! 👀👍
7 years later, and this is still very helpful. Turns out my polar scope was out a lot and this was really screwing up my guiding for astro photography!
Pityu - that's the best explanation I have seen. It's a difficult subject to explain to others (especially beginners, like me) but you did a really, really good job. Plus - big bonus points as English is obviously not your native language, due to your accent. Your English is as perfect as your explanation!!! Well done!!! I wish Celestron would provide a tool to adjust those pesky little screws........
A question or two, if I may please. 1. Is it necessary do you think to have to recalibrate the polar scope each time it is reiserted to the mount? I am just thinking its orientation could shift within the threads?? 2. Do you think it's OK to leave the polar scope permanently inserted to the mount? (Just in case the answer to Question 1 was "yes". ;) )
I installed this polar finderscope on my Celestron mount. When it is screwed in tightly, the text and star diagrams are upside down. Is this the way it's supposed to be?
Hello Pityu, Thanks for the video. Based on the instructions I received with the scope packaging, this seems accurate and I can tell that your reticle stays in the same place. The directions did not say to change RA to be exactly 90 degrees on either side, they just said 'to the right side of the mount'. So your video helped answer that question. However I have another question. When I move my mount from one side to the other, it does not stay in the same place, but it ends up at the same spot. In other words, during the movement, the reticle moves away from the starting position, but by the time I get the mount to the opposite side, the reticle is in the correct spot. However, this is with me going as far in RA as the mount will allow, not just 90 degrees then manually stopping. Do you see if/where this is a problem? Thanks.
Mike Blase Hi Mike! Uhhh... Interesting question! The problem could be one loosened setting screw that should hold the reticle in place. If one is loosened the reticle can move around in a small circle, than returning in it's original position. This is my opinion... I wish you success for fixing it!
Polar scope alignment only need on cheaper Chines mounts! Better quality mounts like the Vixen, it's all done at the factory, no user adjustment is needed!
Never had to! It's only a simple optical tube /w 2-3x magnification, I think! The end focusing lens can be screwed off, if some one crazy about cleaning.
No this is incorrect . You can move Crosshair of the Center of Polar Finder Telescope , so that it is misaligned . And it will still hold on to the Target and wont move , if your Finder is not Centered to the RA axis ..
Of course you can do so! But then ... it's dark outside, you need to fumble with the screwdriver finding the tiny holes in the dark or with read light only. It's much harder ...

I hate skywatchter my equimend over 2000 euros an i work 1 monuth to calibrate the fucking polar scope but not work .. But this micocosmos mill coast 50 euros and not calibrate ????

Thank you. Your demo was much like some others but also showed me how to rotate the big dipper pattern to match the sky.

This is a frustrating process, happy to find your video. Thanks for sharing
Great video. I was having trouble until I watched your video. Many thanks!!!!

That's nicely done. So simply explained - thank you.
A very informative and easy to understand video. Many thanks for for posting this.
Thank you for this !! The only instruction that I could find that didn’t loose me part way was through!
Thanks, been tearing my hair out trying to align my polar scope! Great job
My polar finder will arrive soon and just wanted to say this video was helpful how to center target back and forth from 180*.
Many thanks!, very helpful video. You are a very good teacher.
Perfect video
thanks finally an easy way to learn this
thanks! I was able to calibrate my finderscope using this! Thanks again! very helpful1
Very helpful indeed. Thank you for the explaination.
Thanks! Clear and simple. Good job!
Thanks for this it is a big help now I can put my polar finder in
Excellent tutorial. Just what I needed. Thanks.
Thank you so much for this instruction!!
Thanks for sharing this information. Very informative.
Thanks !
nagyon jol buddy
Very good instructions. Thank you.
Superb! Thankyou very much.
awsome :D :)
Nice job comrade
szia Pityu! ezt a videót megcsinálhattad volna magyarul is! :D nem Trollkodásból mondom! biztos soka hálásak lennének érte! :))

When I calibrate my scope, the object stays within the cross, but the entire image shifts somewhat, even though the image and cross stay together.
Many many thanks!
What motors do you have installed on your mount?

what screwdriver you were used for calibrated?
Thank you.
Why does the mount need to be parallel? I can't lower below 20 degrees.
Well, it doesn't. As long as you have a fixed point you're looking at, it should be fine.
Polar scope alignment only need on cheaper Chines mounts! Better quality mounts like the Vixen, it's all done at the factory, no user adjustment is needed!
Sooner or later you'll have to take it out (ex. cleaning it). Or if you are willing to build your gear. It's good to know how to deal with it. :)
Never had to! It's only a simple optical tube /w 2-3x magnification, I think! The end focusing lens can be screwed off, if some one crazy about cleaning.
Vixen are poor quality Chinese knockoffs mam.
Hi, your mount seems Newtonian EQ3 with a stainless tripod just like mine. Your tracking motors set up, can it be adapted for auto guiding system?
Hi! Unfortunately the EQ3 mount has some serious backlash so it's not very suitable for autoguiding... But You may try.
Pityu Nagy Just as I suspected,,anyway thanks for the attention Sir.
How do I adjust the screws? I see no screws...just 3 teeny tiny holes...
Mine takes a 1.5mm Allen wrench to adjust the screws.
My EQ 5 wont go horizontal
No this is incorrect . You can move Crosshair of the Center of Polar Finder Telescope , so that it is misaligned . And it will still hold on to the Target and wont move , if your Finder is not Centered to the RA axis ..
Why not use Polaris for calibration.why?
Of course you can do so! But then ... it's dark outside, you need to fumble with the screwdriver finding the tiny holes in the dark or with read light only. It's much harder ...
Use Polaris matey boy!
