I am honored to introduce our OCAL electronic collimator

 

pro small picture.jpg

 

 

OCAL electronic collimator is an ideal and superior tool for carring out precise collimation of Newtonian reflector, Ritchey-Chrétien telescope and other reflecting telescope.

Special features

1、Each Collimator has perfect pixel level accuracy in our high quality control.
2、Installing the collimator by M42 threads minimizes the install error.
3、The collimation errors may cause by different visual axis of human eyes in the traditional collimation tools. It can be total eliminated by OCAL.
4、The product can solve the problem of collimating large telescopes,with the assistance of collimation result shows on screen immediately.
5、4 steps collimation by this product. It is easy and suitable for everyone.
6、The product can check if the center mark of the primary mirror is correctly or not.
7、You can share your collimation result by screenshot. Or sending your collimation screenshot to us to get technical support.

For details, please visit the official website www.ocalworld.com/en/

Looks interesting, but I spent most of my time on the video trying to figure out where the bird calls, quacking ducks, owl hoots and dog barks on the audio track were coming from that I missed all of it. What's up with that? It is really distracting.

There’s a “pro” version and a regular version. What’s the difference?

Hello, the computer version supports computer use. The PRO version currently supports Android phones. The number of accessories is also different. The computer version only has one data cable.

Is the product description correct? Does it actually use a 5V battery or is powered via the USB cable?

 

"Focus Type Manual-and-auto" could be changed to read "Focuser Type" or "Works with both manual and motor focusers" Not all motorized focusers are automatic focusers.

 

You should consider mentioning or linking the product warranty, to include both the coverage and the such information as who pays for the shipping.

 

Good luck with your new product.

Wow, I have to say, this looks amazing. I've used many collimation tools from lasers to Takahashi collimation tools, and this looks better than all of those.

I would love to see video of an RC collimation. I struggled the most with RC telescopes.

Thank you, there is a problem with the laser collimator, its own collimation is a big trouble.
Also, the laser collimator cannot collimate the secondary mirror
Takahashi’s collimator is a good tool, but it is also a big trouble for the secondary mirror. For those telescopes that do not have the secondary mirror mark

I have tested RC, but I didn't make a video for a short time because I don't have an RC telescope myself, but I have pictures, I will post them.

RC collimation is much more difficult than SCT, and the collimation method is also very different from SCT. I will provide a tutorial later.
We have too many successful experiences with Newton mirrors. If you have any questions about the collimation of Newton mirrors, you can ask them at any time.

I have a few questions : 

- You say you don't have any video of a RC collimation, but is there a description of the procedure for the RC in the manual (which can't be downloaded as the link on your website returns a 404).

- Your software is all Windows. Any plan to support Linux and/or macOS (I exclusively run Linux in the observatory and macOS in the rest of the house, no Windows here).

 

Thanks.

Hello, sorry, there is no RC collimation video and manual at the moment, because there are not too many successful cases, so I am cautious about the RC collimation for the time being, but I will verify it soon.
Due to cost issues, the computer version currently only supports windows. If the number of customers for IOS and Linux systems increases, we will consider starting software development immediately.

Thanks for the quick response. As my use case is collimating a RC-250 on Linux.. looks like this is not going to work for me right now.

I'll keep an eye on it to see when there is more data on RC collimation and Linux support (IOS support would be an acceptable solution if Linux doesn't come soon).

Me too. This is the fastest easy looking collimation I've seen, and it threads on. Almost all issues I ever had were mechanical in nature. Whether it were a clamp ring clamping on to a laser collimator that would shift around, or even the Takahashi collimation scope which has a sliding focus which wobbles and massively moves around what you're looking at.
