Wizard Nebula, Asteroid Adamblock

Posted: 4 November 2021

Although Sunday night, 31 October 2021, was clear I didn't open the observatory due to commitments the next day. Monday, 1 November, and Tuesday, 2 November, were cloudy. The sky cleared on Wednesday, 3 November.

Open: Wednesday, 3 November 2021, 1808 MST
Temperature: 78°F
Session: 1686
Conditions: Clear

12" f/8 LX600 w/StarLock
2" 24mm UWA eyepiece
2" UHC filter
Focal reducer


1814 MST: LX600 ON, StarLock OFF, High Precision OFF.

Viewed the planets Venus, Saturn, and Jupiter, 102X.

Prepared the D850 DSLR for imaging.

1827-1850 MST: relaxed on the observatory patio bench while waiting for Astronomical Twilight to end.

Mounted the D850 DSLR at prime focus + focal reducer + UHC filter, focused on the star Shedir, locked the 12" mirror, and SYNCed on Shedir.

Took six StarLock autoguided, 5 minutes, ISO 12800, images of NGC7380 (Wizard Nebula). This is a stack of the six images, effective exposure 30 minutes.


I then removed the UHC filter to image Asteroid (172525) Adamblock, Mag.+ 18.9, named for Adam Block, an Astrophotography Wizard.

I used SkySafari 6 Pro on my iPhone to GOTO Asteroid Adamblock via a Wi-Fi connection to the 12" LX600 telescope. SYNCed on the star Hamal.

1952 MST and 2052 MST: took StarLock autoguided, 5 minutes, ISO 6400, images of the asteroid. In between the two images I relaxed on the bench and enjoyed looking up at the night sky. The asteroid appears as the faint dot at the center of the images. Seeing was not great when I was imaging Asteroid Adamblock.
