Hi All,

I have put together an instruction set on how I collimate my RC8, if anyone is interested.
It also covers some adapters that are required and where to get them.

Download the PDF if you wish. the file is about 51Mb.

In photos 1 and 4 it appears that the spider has a long leg, top left.

Or am I imagining things?

Hi starhunter50,

 

Yep, your scope is a very long way out of collimation.

From the images you have posted it is impossible to determine where the error is and would only be guessing.

 

Although you have an RC6" the general collimating procedure would be the same however, the distance between the two mirrors would more then likely be different.

 

Now here the thing,

your first image shows the the small white ring dead center, and would indicate that the secondary is collimated, and the primary is out of collimation due to the offset of the spider, so one would make an adjustment of the primary to fix this, however, this will not solve the problem as now you will see the the small white ring is no longer in the center, which would indicate the secondary was also out of collimation as well.

 

You need the correct collimating tools to get it right, then just follow my instruction manual and you should be one happy chappy......I'm sure.

 

Robin
