• Target: M 13, Hercules Globular Cluster[1]
• Const: Hercules
• RaDec: 16h41m 36°28
• Type: Globular Cluster
• Scope: AT102ED
• Setting: 200x

Started off wanting to push M13 to a higher magnification. I was able to get similar viewing as last time with the x2 barlow at 200x. The conditions tonight didn't seem as crisp as the last night, but I was still able to get a sea of smaller stars in view using AV.

• Target: SAO 46574 (HD 156074)[1]
• Const: Hercules
• RaDec: 17h13m 42°06
• Type: Star (Carbon)
• Scope: AT102ED
• Setting: 34x

The description stated that it was about 1.25 degrees SW of M92. So I started by locating M92; then using my FOV at 34x (which is about 1.2 degrees) moved M92 to the NE edge of the FOV. The star was very pale, and didn't contrast much with other stars in the vicinity. It stood out a little more because of a hint of yellow that the other stars lacked.

• Target: M 92[1]
• RaDec: 17h17m +43°80
• Type: Globular Cluster
• Scope: AT102ED
• Setting: 100x, 240x

The smaller version of M13, very similar in appearance. Great view at 100x. I could see as much detail as with M13. Tried pushing to 220x, the detail was still decent. AV helps bring fainter stars into view.

Very deep orange/red color. Stands out vibrantly among all the other stars.
