Posted: 26 October 2017
Open: Wednesday, 25 October 2017, 1808 MST
Conditions: Clear, hazy
12" f/8 LX600 w/StarLock
2" 24mm UWA eyepiece
1.25" 40mm eyepiece
1.25" 15mm eyepiece
iPhone 8 Plus
1815 MST: LX600 ON, StarLock OFF, High Precision OFF.
Viewed Saturm 102X.
Next, viewed the Messier globular clusters M2 and M30, 102X. I would image both of these later this session.
Viewed the Moon, 102X and 61X.
Mounted the iPhone 8 Plus on the 40mm eyepiece using the Levenhuk adapter. Took this afocal 61X image of the Moon using the iOS app NightCap Camera:
Slewed to M2 (globular cluster) and SYNCed the AutoStar. Switched to 163X. The view of M2 was nice. Mounted the iPhone on the 15mm eyepiece.
1840 MST: StarLock ON. Took StarLock autoguided iPhone 8 Plus images of M2 and M30 globular clusters using NightCap Camera (Long Exposure, Light Boost, ISO 8000, 1/3sec, 1 minute exposure).
I discovered during post-processing that autoguiding was not very accurate. Will redo these images on a future session.
Slewed to the star Altair and SYNCed the AutoStar. Slewed to M71 (globular cluster). Needed to wait a few minutes for the object to clear the observatory dome. 1900 MST: StarLock OFF.
1935 MST: StarLock ON. Did this StarLock autoguided iPhone 8 Plus image of M71 globular cluster using NightCap Camera (Long Exposure, Light Boost, ISO 8000, 1/3sec, 1 minute exposure.
Autoguiding was better for this image.
1939 MST: StarLock OFF.
Viewed M71 (globular cluster), 102X.
Then viewed the open clusters M52, M103, and the Double Cluster, 102X. I plan to image these with the iPhone on the next session.
1948 MST: LX600 OFF.
Began closing the observatory after a long day of activities.
Close: Wednesday, 25 October 2017, 2000 MST
