Your welcome, could well be that I simply don't know how to do it. I didn't have any documentation from Sharpstar or Ocal, had to figure it out as I went along
Very helpful video; much better than some of the other vids on the Ocal. Perhaps you could transcribe the lost audio around the 17 minute mark. The audio gets v distorted and is completely unintelligible. Thanks!
I tried unfortunately it was corrupt so badly I couldn't figure out what I was saying. But glad you found it useful. Future videos will have better audio
Hi, such a question: Did you tried to collimate maksutov-newtonian telescope with this device? Looks like you are giving much more in-depth presentation than other sources which I found - good job!
Hi, sorry for the late response, for some reason I stopped getting notifications for comments. Unlike the bigger version of this scope, the coma corrector is not easily removable on this scope. Or maybe I just haven't figured it out. However, I have tested the results under the stars and got good results
I recently purchased the SharpStar 15028HNT and am looking for collimation tools other than the little 1.25" eyepiece that came with the scope. I've been considering the Ocal, so seeing a video of it on the little brother of my scope is very helpful! One part of the video I found a bit confusing was when adjusting the secondary, you stated there was no way to adjust the physical position of the secondary. I understand there is no way to change the length of the spiders; however, the secondary can be moved up/down the tube via using the big center screw - just like any other newt. Further, you can rotate the secondary as needed. Would you mind explaining a little bit more what you mean around the 13:10 mark of the video?
I have since learned about the ability to move it in or out, but you can't use the spider to center it. I have purchased the unit on display and use ocal to collimate it. If I move it to a position where mirror is perfectly centered to focuser I can't reach focus. If I move it out a bit to reach focus, I get uneven illumination in my frame. Honestly despite these foibles, I still like the scope
Yes it does, I used it to collimate a badly out of collimation SCT that was hard to collimate under the stars because it was so far out of collimation. Then I fine tuned the collimation under the stars
Please remember that for some telescopes like RC design you can't really use laser to collimate and laser isn't always accurate enough for f2.8. Furthermore, being a tutorial I had to take my time and over explain
Your video is THE BEST for a proper understanding of the OCAL. Many thanks!
Glad you found it useful
شكرا الك فيديو مفيد جدا وخصوصا لي انا استخدم sca260 sharpstar
very well explained
Thanks for the feedback. Love my Ocal
Good job! Thanks for the video! Very informative!
Your welcome, we plan to make more videos of this style
Nice video, thanks for sharing
Glad you liked it
Thank you for the video very well done. I just wish that the scope you had used was fully adjustable.

I think you have to check „center offset“ when adjusting your focuser position
Yeah, figured that out and how to zoom after the video. Nice product, shame it doesn't come with clear instructions

Hi, never tried as I don't have one
Was a coma corrector installed during collimation?

Have you tried collimating it with OCAL? I have the same telescope and am having some difficulties with collimation using OCAL and other tools.
Does this work with a SCT?
Yes it does, I used it to collimate a badly out of collimation SCT that was hard to collimate under the stars because it was so far out of collimation. Then I fine tuned the collimation under the stars
Simplify?
