Dual mounted my Apo's on my Atlas Pro May try this out under the stars tonight
Be sure you let the SVA130 cool down long enough, you may be surprised at the eyepiece views when comparing them at high magnification until the SVA130 cools. Set them outside without any sunlight falling on them a few hours before sunset and the acclimation time will be shorter. My experience with medium size air spaced triplets is they need a good 30-120 minutes cooling time depending on the temperature difference between where they were stored and the observing time temperature. Also know that while you may not feel it any sun directly or indirectly hitting the tubes will warm them and the glass and cells. Keep them in the dark when placing scopes outside to speed waiting time for acclimation. Take notes and get back to us tomorrow!
