Since I'm in California, I'm usually on grass when I do my back yard astronomy.
When I've used light mounts, I usually push the tripod legs into the ground so I know the feet are planted and secure so the leveling doesn't change. Also, I think its better to be fully set up before making your final leveling adjustments.
If the ground is overly dirty or wet, a tarp might help you stay more clean. We use to use a series of tarps when me and friends would set up at a friends place who had a big opened field. He would mow the field down every month or so, but the tarps kept dust and dirt from making things dirtier. Usually, I avoid dirty areas because dust can cling to dew on your front element.
Anti-vibration pads wont make any difference in the grass regarding reduced vibration.
I noticed that when I leveled the Celestron NexStar 90SLT mount, and then added the optical tube to the mount, the mount was no longer level (in the middle of a grassy field).
Should I wait until the OTA is on the mount to level it? I thought it had to be leveled before the OTA is added?
Should I place a plastic/vinyl tarp under the mount if it is being set up on grass? I would be worried about the tripod slipping on a plastic/vinyl surface.
Would using anti-vibration pads on grass be helpful or unhelpful?
