  1. Hi Andy, I'm Carole's friend of many years standing, we both belong to the Orpington Astronomical Society and post our astro images on the forum there. Carole sent me an email saying you were looking for fellow astronomy fiends in Manche, I live about 45 mins south of Cherbourg. I also have been hankering after a bit of astro-socialisation, but there doesn't seem to be a local association or club that's still active. I'll PM you. Duncan
  2. Checking collimation in a SCT?

    Hi I'm Dunc and new to the SGL but a long time member of the Orpington Astronomical Society, The Duncan Mask document was drawn up by me based on something I read on the web, I used to have great difficulty collimating my 8" LX90. I still do as the dratted thing needs collimating every time it's used. I tried out of focus stars etc. but they were too imprecise especially given my far from perfect eyes. It takes 10 minutes, scissors and a piece of card to make the mask and it will save you hours *and* you will be certain your SCT is collimated correctly. My next astro kit project is to dismantle and reassemble the secondary holder to find out why it won't hold collimation. Should have done it years ago!
