Extragalactic Supernova Project imaging
Posted: 27 April 2019
Open: Friday, 26 April 2019, 1810 MST
Conditions: Mostly clear
After several days when the daytime outside air temperature was over 95°F I decided it was time to prepare the observatory air conditioner for its daily use. Opened the outside vent and set up the timer for automated operation.
I then relaxed on the observatory patio bench as sunset approached.
1904 MST: sunset.
I continued relaxing on the bench to watch the stars come out.
1933 MST: back inside the observatory. Prepared the D850 DSLR for later galaxy imaging for my Extragalactic Supernova Project.
1938 MST: LX600 ON, StarLock OFF, High Precision OFF.
I then did some more work with my new nightscope. I will post my review soon.
2015 MST: mounted the D850 DSLR at prime focus, focused on the star Procyon, and locked the 12" telescope mirror.
2020 MST: High Precision ON.
Slewed to the first target, NGC3359.
2030 MST: StarLock ON.
Unfortunately, for some reason the StarLock could not get a lock on a suitable guidestar. So my exposure time was limited. This is an unguided, 90 seconds exposure, ISO 6400, White Balance 5000K, image of NGC3359:
The StarLock did get a successful lock when imaging NGC3198 for this StarLock autoguided, 5 minutes, ISO 6400, WB 5000K, image:
I hope to get a longer exposure of NGC3359 on a future session.
2103 MST: StarLock OFF, High Precision OFF.
Removed camera. Viewed M104 (Sombrero Galaxy), 102X.
2111 MST: LX600 OFF.
Close: Friday, 26 April 2019, 2123 MST
Session Length: 3h 13m|
