Observations with the SV110ED (6-24-15)

The sky was clear until around 11:30 tonight.  I mounted the SV110ED on the Tak EM-10 and took a ride through the eastern sky.  Objects observed included

1) Globular clusters: M92, M13, NGC 6229, M56.

2) Planetaries: M57, NGC 6210 (in Hercules; small and trapezoid shaped, faint around the edges and irregular), NGC 6543 (Cat's Eye Nebula, in Draco, shaped like a cat's eye, and some faint nebulosity around it).

3) Numerous double stars, but the most fun was Al Fawaris, aka Delta Cygni.  The separation is 2.7" but at magnitudes 2.91 and 6.27.  I pumped the magnification to 388x before I could clearly see the dimmer star, and then only when seeing did not wash it out.  Cool.  Also, 17 Herculis was great, as was Sarin and many others.  Could drive a truck through the Double Double at 194x, but it was cleanly split at 77x.

The scope was on one tonight: textbook images, and seeing was not bad.
