Oscillations or Wind Shake?

Monday, June 1, 2015 10:14 AM

Problem(s) Encountered:

Several mages showed oscillations in the N/S direction.  Telescope

was pointed at dec = -8, h.a. = +1. About half the images in

this position displayed an oscillation.  Most of the light

was in the central image, but there were many excursions N/S.

These images are not useable.


Checking the image left, it looks like some wind shake to me.  This seems to coincide with the telescope pointed to the S/SW with breezy conditions coming out of the S/SW last night.

Raised the vertical weights from 3125 to 3275 to bias balance slightly to the top.  This should keep the secondary anchored a bit more in any gusts.
