Do you know what magnification you used, Star Alert?

 

Clear skies from Aubrey. 

Hmmm, good question. I can’t remember exactly, but I was using an 8.5mm XF most of the night. So 365x. If it wasn’t the XF, it was the 3.4mm HR.

Seeing was so poor Thursday night, that I couldn't split Izar with a good 12 inch reflector.

That is very surprising, John. 

 

Maybe next time you will have success with Izar.

Aubrey,

Frequently, seeing is so poor here that no airy disk is even remotely visible.  Star images may appear to be 3 or 4 seconds across, like little boiling blobs.  The terrain is very rugged, and cut by hills and valleys, which may contribute to turbulent conditions.  Thursday night, we had a north wind, which is unusual this time of year.
