vibration

[matcat]

Astrophotography has its problems. I have one. Vibration from the shudder opening and closing, im thinking about trying styrofoam blocks under the tripod legs. what do you think?

1) Get a big piece of black cardboard.<br />2) Hold the cardboard in front of the telescope to block the light<br />3) Open the shutter manually.<br />4) Wait for vibration to dampen out.<br />5) Remove the cardboard.<br />6) Wait for the exposure time to elapse.<br />7) Put the cardboard back in front of the telescope.<br />8) Close the shutter.<br /><br />Don't touch the telescope with the cardboard.
