NGC 6618-6645

NGC 6618 (M17). Swan Nebula. Sgr. At 24 mm with CLS filter, displays the eponymous shape: a massive nebula greatly extended E-W with a hook running S from its W end. Several bright stars surround the hook.

NGC 6633, OC, Oph. Large and bright, poor, no concentration. A larger and a smaller triangle of bright stars, between them a broken line of fainter stars. 24 mm, CLS filter.

NGC 6645, OC, Sgr. Adequately framed in the 20' field at 24 mm. Relatively poor and scattered; the periphery is dominated by comparatively bright stars; fainter stars appear gathered toward the center.

NGC 6664-6712

NGC 6664, OC, Sct. HVIII-12. A poor, scattered cluster that prominently contains a group of 6 stars that are arranged in a roughly equilateral and an isosceles triangle. 24 mm, CLS filter.

NGC 6694 (M26). OC, Sct. In a figure possibly involving foreground stars, this cluster has an integral-sign arrangement of stars running through it. It is dominated by a triangle of stars with the mass of fainter stars near its apex. 24 mm, CLS filter.

NGC 6705 (M11). OC, Sct. Beautiful rich cluster of largely uniform stars. The "wild duck" shape is actually outside the main mass on the side facing a bright star pair. The main mass has a more vague V shape with the lucida at its apex. 24 mm, CLS filter.

NGC 6712, GC, Sct. Diffuse nebulous patch at 24 mm with CLS filter. Remains unresolved at 8 mm.

NGC 6823, 6830

NGC 6823, OC, Vul. 24 mm. Resembles Corvus at the apex of which is a small group of stars that itself resembles Orion. The tabular dimensions include bright outliers.

NGC 6830, OC, Vul. 24 mm. Crossed by a line of 5 moderately bright stars. Two brighter stars point at the middle one at right angles. Opposite these two, fainter stars are scattered.

NGC 6802-6819

NGC 6802, OC, Vul. Can just be seen at 24 mm. Small. At 8 mm, not resolved, 3 moderately bright stars nearby. Greatly extended.

NGC 6809 (M55). GC, Sgr. In the trees at transit.

NGC 6818, PN, Sgr. Small, nonstellar at 24 mm. At 8 mm, round, no concentration, soft edges.

NGC 6819, OC, Cyg. Not in H400. Foxhead Cluster. Appears smaller than the tabular size, 26', unless the outlying stars are counted. Flanked by 2 moderately bright stars, an elongated pentagon of fainter stars. An unresolved mass that is much fainter is inside the short side of the pentagon. 40, 24 mm.

NGC 6755-6781

NGC 6755, OC, Aql. 12 mm. Cluster of faint stars, the brightest of which run at right angles with a line of stars in a brighter cluster that is adjacent (Czernik 39). [Cz 39 is smaller than the cluster now identified as NGC 6755. It may be a separate cluster astrophysically, but it is certain that the original NGC 6755 is the entire grouping.]

NGC 6756, OC, Aql. Barely resolved at 8 mm, shimmering with faint stars. Off-round near a vertex inside a triangle of brighter stars. A much brighter star near outside the triangle.

NGC 6779 (M56). GC, Lyr. 8 mm. Resolved across the core. Appears triangular and little compressed due to the brighter stars on its periphery.

NGC 6781, PN, Aql. 24 mm. Just seen without a filter. With OIII, round, annular, brighter toward the bright star in the field.

NGC 7448, 7479

NGC 7448, GX, Peg. Faintly visible next to a star at 8 mm. 8 s, F/3.3: greatly elongated, small bright core, unequally bright extensions.

NGC 7479, GX, Peg. C44. 8 s, F/3.3. Small bright core. One extension curves slightly before reaching a star. The extension opposite curves around another star.

NGC 7209-7331

NGC 7209, OC, Lac. 8 s, F/3.3. Fills the 20' field with a uniform assemblage of moderately bright stars.

NGC 7217, GX, Peg. Small, round, gradually brighter to the middle. Edges diffuse. 8-40 s, F/3.3.

NGC 7243, OC, Lac. C16. 40 mm. Elongated cluster that seems to consist of two slightly unequal parts.

NGC 7293, Helix Nebula. PN, Aqr. C63. In the trees at transit.

NGC 7296, OC, Lac. 40 mm. Small, poor, moderately well-detached cluster that is defined by an incomplete circlet of stars with a brighter, warm-tinged star outside it.

NGC 7331, GX, Peg. C30. Lens-shaped in 40 mm. 8 s, F/3.3 shows asymmetry in the lens-shaped core, 15 s brings out the very large halo and a dust lane on one side of the core. A small galaxy is nearby (NGC 7335).
