Got home from our trip to Erik's Ranch. Unpacked the car quickly then setup the telescope.

- Target: ε Lyrae[1]
- Const: Lyra
- RaDec: 18h44m +39°4
- Type: Star (Multiple)[2]
- Scope: ST80
- Setting: 150x, 1/2 stop-down
- Double: AB: 350°, AB-CD: 170°, CD: 80°

I could not see the primary companion without tapping the lens (B). The secondary companion (D) showed up but without a clean split, looked more like an extension of (C). Took a bit to find all 4. Pretty cool double-double.

Very easy split. Similar in color, but the sibling looks like it has a little more purple?

Another easy split. The sibling is more noticeably faint.

- Target: M 57, Ring Nebula[1]
- Const: Lyra
- RaDec: 18h53m +33°2
- Type: Planetary Nebula
- Scope: ST80
- Setting: 40x, AV
- Image: ../images/2022-8-21_M57.jpg[2]
Very small. Just a subtle fat dot on a dark background. Looking directly at it will make it disappear! AV pops it back into view with a little definition. Getting some "irregularity" in the glow around the center.

Took a little to determine which nearby star was the sibling. Both are nestled between β and ν Lyrae.

- Target: M 56[1]
- Const: Lyra
- RaDec: 19h16m +30°11
- Type: Globular Cluster
- Scope: ST80
- Setting: 40x, AV
- Image: ../images/2022-8-21_M56.jpg[2]
Very faint. AV isn't required for detection, but is necessary to get an observation of the size and shape.

Cool pair! The primary is very orange / yellow. The secondary is a colder white, a little less bright.

I would have missed it if my star chart didn't tell me it was there. No "concentration" of light or glow, more evenly distributed and spread out.
