  2. Thanks guys, Have to be really careful................................ P.
  3. Hi, Just getting into astrophotography and when I took the camera off the focus tube of the telescope (skywatcher 200) last night, I noticed that the secondary mirror was very dirty. I used a tissue as I thought that it may have been dew. It came up ok but my worry is that it may have a delicate coating or that it may even move out of alignment. Just interested if anyone else has had this problem and how they dealt with it. Also, more importantly, if the primary mirror gets dirty, (dew and dust etc.),how on earth is that supposed to be cleaned. Any help is welcome. P.
  4. Thanks guys, I'll be hopefully using a canon 40D with a skywatcher 200 on an EQ5 mount. Any and all suggestions will be gratefully received.
  5. Hi, being a complete beginner to imaging, I have a very basic question. I read somewhere that the only stupid question is the one that's never asked so here goes. When a camera is attached to a telescope both the camera lens and the telescope eyepiece are removed, so where does any magnification come from, or is it only in the image enlargement. (Bet all beginners think about this but are too embarrassed to ask).
