In the last time I finally understood the basics collimation steps, mostly due to Jason´s excellent posts. Thank you Jason!!
Now, I have been performing collimation with my collimation cap in the last three years and that´s the only tool I own. I will be ordering a chesire/sight tube soon, but meanwhile I´m using a complement of the basic CC to achieve the focuser axial collimation.
So, once I achieved this allignment, I started to work with the secondary placement. My focuser is fairly squared and I measured the spider vanes to be in the exact center of the tube. My secondary has a classic offset, I think.
So, looking at the reflections I centered the secondary with the central bolt, always making iterations with the focuser axial alignment. But now I´m stuck in the final step, I think it´s a rotation issue, but I cannot make the two allignments well, it´s seems that at this point I cannot separate at all the tilt-rotation movement.
Or maybe is the spider? I don´t wan´t to touch the spider any more as it´s delicate and I think this is the best position, centered and with no vanes forced to the side.
So, should I accept this secondary placement or I can do better?
Here are some pictures
This are the home made collimation cap and the aditional tool that I made.
