Collimating the telescope

Sign in to follow this  


Well being new to all this and doing much research and reading up I knew I would need to check the collimation of the telescope so bought a collimation cap for this

With the instructions provided with the telescope it was pretty straight forwards to do and as I have also watched a few youTube videos and read some how-to's so I knew what to expect and do

So firstly fitted the collimation cap and check things - things were not ideal (see attached image)

So using the instructions the first thing to do was alter the secondary mirror (the one that direct light into the eyepiece) which was straightforwards so I could see the three tabs on the edge of the primary mirror (in the attached image you can only see two)

Once this was done it was time to adjust the primary mirror. There are three holding screws and three allen key bolts, the allen key bolts move\adjust the mirror and the holding screws hold it in place. So following the instructions I attempted to loosen the allen key bolts with no luck using the smaller provided allen key - I had to go into the shed and get a much smaller allen key that would fit. So by adjusting things I got the central circle lined up and tighted up the screws.

All in all 20 mins to read through the instructions and do the adjustments - now I have done it once its will be more straight forwards next time
