  1. When viewing/imaging to the south your scope will be east or west of the pier/tripod...
  2. Both these mount styles given a clear horizon are able to point the scope to any part of the sky. Their only differences will likely be how far past the meridian they can travel when the scope is in a near vertical or vertical position. If both where mounted on a pier rather than a tripod then the distance between the centre rotation axis of the RA axle and the top mounting plate will determine how far past vertical the scope can point. The physical length of the scope will be a factor in when or if the focuser/camera fouls it's support.
  3. I think you just replace one adjustment screw at a time so you maintain the mirror's overall position not all three at once? Cut a slot in the 'washer to allow it to pass the centre bolt.
  4. Hi Brian, I was expecting the stars to have more colour. There's hints of colour in the halos. Depends on the processing software etc. Great image though, don't get me wrong. Waiting for my CEM60 standard to arrive...
  5. Like that. I suspect the 'colour' has been muted by the Ha. Have you one with just the RGB subs?
  6. Firstly you need to balance your mount on both axles. Next loosen both the RA and Dec axis locks so the mount will move freely. Then tell the mount to go to it's zero position. Once the mount has zeroed you can then with a spirit level put the Dec shaft so the weights are pointing vertically down - lock the dec axis, then rotate the RA axis so it is pointing towards north and lock it. The mount now knows where it's pointing and you should then be able to do a one, two or three star alignment.
  7. Easiest way (and free!) is to set a custom white balance with a sheet of white paper under whatever illumination source you intend to use. Usually you find custom white balance under the white balance settings within the camera menu's - check your manual to set how your particular camera needs to be set-up for custom balances.

  9. Superb piece of imaging, the processing I guess was another feat too.
  10. Might be worth taking the focus motor off and do a manual in / out to see what happens. My EDGE HD8 definitely 'feels' different at each end of travel
  11. Orion 100mm Tube Rings – £25 Take this please - pm sent
  12. Just bought a CEM60 standard and tri-pier (where's that postman...)
  13. Great start - don't be tempted to make the background too dark (black) you'll loose a lot of fine detail around the edges of objects like M1. I take it from the exposures your running unguided - can you record PEC for the NEQ6 that should soften drive errors a bit.
