D7000 DSLR Imaging: M38 Open Cluster, Asteroid 6 Hebe

Posted: 25 October 2014

Opened: Friday, 24 October 2014, 2307 MST
Temperature: 66°F
Session: 734
Conditions: Clear

Slewed to M38 (open cluster), my next Messier catalog imaging target. Began preparing for 8" prime focus imaging using the D7000 DSLR. Did a focus test on the star Capella using the Bahtinov Mask. This is M38, 30 seconds (unguided), ISO 640:


Then powered on the GC Wi-Fi Adapter and used SkySafari Pro on the iPhone to GOTO Asteroid 6 Hebe. Did some 30 second (unguided) exposures. Will take a second image Saturday night to check movement in 24 hours.

2355 MST: viewed Asteroid 6 Hebe, 83X. At least, I think I did. I did star comparisons using SkySafari Pro.

0000 MST: viewed M1 (Crab Nebula), 83X. Some structure visible.

Lastly, did some sky quality measurements. Got 21.01 with the SQM-L meter. Still not as dark as normal; still have relatively high humidity.

Closed: Saturday, 25 October 2014, 0019 MST

I added a new Photos album: iPhone Astrophotography to showcase some of my iPhone astrophotography.
