Posted: 19 January 2023

Cloudy skies returned on Friday, 13 January 2023. Rained (0.39") arrived on Sunday, 15 January. Rain (0.95") continued on Monday, 16 January. Tuesday, 17 January, was a rainy (0.78") and windy day with some snow in the morning. Cloudy skies continued until Wednesday, 18 January.

Open: Wednesday, 18 January 2023, 1818 MST
Temperature: 49°F
Session: 1819
Conditions: Mostly clear

12" f/8 LX600 w/StarLock
2" 24mm UWA eyepiece


1829 MST: Dome Cover OFF.

1833 MST: LX600 ON, StarLock OFF, High Precision OFF.

Viewed Venus, Saturn, Jupiter, and Mars, 102X.

Viewed M42 (Great Nebula in Orion), 102X.

1841 MST: High Precision ON.

Viewed NGC584 (galaxy), which would be my first Herschel 400 Catalog galaxy I planned to image this night, 102X. I then prepared the D850 DSLR for imaging, mounted the D850 at prime focus, focused on the star Rigel, and locked the 12" primary mirror.

1900 MST: StarLock ON.

These StarLock autoguided images were 5 minutes, ISO 3200, exposures.

NGC584 (galaxy), note 3 other faint galaxies

NGC596 (galaxy)

NGC598 (M33, Triangulum Galaxy)

I then imaged NGC613 (galaxy), but thin clouds were slightly obscuring the view. This is the best StarLock autoguided, 5 minutes, ISO 3200, image. I will re-image it on the next session.


Clouds were increasing. This StarLock autoguided image of NGC524 (galaxy), 5 minutes, ISO 3200, is the last image I took. Note that there are four other galaxies in the image.


Due to increasing clouds, I ended the session.

2003 MST: LX600 OFF.

Close: Wednesday, 18 January 2023, 2018 MST
Temperature: 36°F
Session Length: 2h 00m
Conditions: Partly cloudy

For those interested, I have split up my iPhone Astrophotography Album into separate pages for each model: iPhone 13 Pro Max, iPhone 11 Pro Max, iPhone 8 Plus, iPhone 6s Plus, iPhone 5s, iPhone 4, and the original iPhone. I have also split up my Sky Photography Album by years and added some sky photos for 2009 and 2010.
