Looking at stars

Advanced VX 6” SCT

Finally Rob sold his two telescopes lately and got a new one.
I am not sure from the deck how much we can see stars, but there is a nice spot in walking distance in Sellwood, we are planning to look for starry night!
For the test, we pointed the telescope to a bird that was quite far away. I took photo of the bird which was on top of an electric pole. Then I took photo of the bird with the telescope. The result was far better than previous telescopes! Rob apparently made a happy choice for this one.

However we could not much test the stars at night because of clouds. We are waiting for a clear night.

In the photo underneath the bird, I used Sony Alpha 65 with Sony SAL-1680Z 16-80mm f/3.5-4.5 Carl Zeiss Vario-Sonnar T* DT Autofocus Lens
