Venus & Mercury, Thor's Helmet Nebula
Posted: 27 February 2025
Due to an early morning meeting the next day with some local ex-military fighter pilots, I did not open the observatory Tuesday night, 25 February 2025.
Open: Wednesday, 26 February 2025, 1815 MST Temperature: 83°F |
Session: 2076 Conditions: Clear |
Equipment:
12" f/8 LX600 w/StarLock

Focal reducer
2" UHC filter
Camera:
iPhone 15 Pro Max
D850 DSLR
1818 MST: Sunset.
1823 MST: LX600 ON, StarLock OFF, High Precision OFF.
Viewed Venus, 102X. A nice crescent phase was visible. Viewed Mercury, 102X. A small disk was seen.
Prepared the D850 DSLR for imaging.
1837 MST: Relaxed on the observatory patio bench.

1930 MST: The Zodiacal Light was visible in the western sky.
1932 MST: Back in the observatory. High Precision ON.
Slewed to NGC2359 (Thor's Helmet Nebula). Some faint nebulosity was visible, 102X.
Mounted the D850 DSLR camera at prime focus + focal reducer + UHC filter, focused on the star Sirius, locked the telescope mirror, and slewed to NGC2359.
1942 MST: StarLock ON.
After doing two short framing test images, I began doing StarLock autoguided, ISO 4000, exposures of NGC2359 (Thor's Helmet Nebula). Unfortunately poor seeing resulted in poor autoguiding. I finally gave up doing any imaging on this session. This is the only usable image I got (278 seconds).
I will image Thor's Helmet Nebula on a future session. I have imaged it several times in the past with different cameras and filters.
2000 MST: StarLock OFF.
Viewed NGC1977 (Running Man Nebula), 102X. I enjoy viewing and photographing this nebula. I included an image that I had taken on the cover of my autobiography Finding my Way to the Stars.
2009 MST: LX600 OFF.
2019 MST: Took a Sky Quality reading and reported the result to Globe at Night.
Close: Wednesday, 26 February 2025, 2023 MST Temperature: 63°F |
Session Length: 2h 08m Conditions: Clear, SQM 20.65 |
