Open: Wednesday, 11 November 2020, 1819 MST Temperature: 65°F |
Session: 1551 Conditions: Clear |
Equipment:
12" f/8 LX600 w/StarLock
2" 24mm UWA eyepiece
Focal Reducer
HA filter
Camera:
D850 DSLR
1821 MST: LX600 ON, StarLock OFF, High Precision OFF.
Viewed Jupiter and three moons, Saturn and three moons, and Mars, 102X.
Then prepared the D850 DSLR for imaging Sharpless 2-173 (Phantom of the Opera Nebula). Mounted the D850 DSLR at prime focus + focal reducer + Hydrogen-Alpha filter. Focused on Mars and locked the 12" primary mirror. Slewed to Sharpless 2-173.
1845 MST: StarLock ON.
Took StarLock autoguided ISO 6400 and ISO 12800, White Balance 4000K, images using exposure lengths of 1, 5, 10, and 15 minutes. Seeing was excellent this night, yielding excellent autoguiding. This 15 minute, ISO 12800, image (with a lot of image processing and converted to black-n-white) shows the Phantom's face the best. (He is looking up towards the upper left corner.)
1939 MST: StarLock OFF.
Began closing up due to an early morning commitment.
1951 MST: LX600 OFF.
1958 MST: did a Sky Quality reading.
