1749 MST: LX600 ON, StarLock OFF, High Precision OFF.

Viewed the crescent Moon, 102X. Nice Earthshine.

Took this handheld "selfie" with the iPhone 13 Pro Max photo using the Camera app (Night Mode, 3 seconds, front camera). It shows the 12" telescope, the Moon, Earthshine, and some clouds in the western sky.

Mounted the D850 DSLR at prime focus + Starizona Filter Slider. Took these images of the Moon (1/250sec and 2 seconds, respectively, ISO 400).


1831 MST: High Precision ON.

Viewed two more Herschel 400 Catalog objects, 102X: NGC7662 (planetary nebula) and NGC7686 (open cluster).

Mounted the D850 DSLR at prime focus + filter holder, focused on the star Altair, and locked the 12" primary mirror.

Slewed to NGC7217 to begin imaging more Herschel 400 Catalog objects. No filter was used for these images taken with various exposures (1 minute to 5 minutes, ISO 400, 800, and 3200).

1849 MST: StarLock ON.

NGC7217 (galaxy)

NGC7331 (galaxy)

NGC7448 (galaxy)

NGC7479 (galaxy)

NGC7662 (planetary nebula)

NGC7686 (open cluster)

I have now observed and photographed all the NGC7000s objects in the Herschel 400 Catalog for my Herschel 400 Catalog Astrophotography Album.

2019 MST: Dome ON.

Inserted the Explore Scientific 2" UHC filter into the filter holder, focused on the star Aldebaran, and locked the mirror.

Took this StarLock autoguided image of NGC1579 (Northern Trifid Nebula), 5 minutes, ISO 3200.
