iPhone 13 Pro Max Messier Open Clusters, Crab Nebula

Posted: 6 December 2021

Saturday, 4 December 2021, was mostly cloudy. I tried to observe a pass of the SpaceX Starlinks satellites that were launched on 2 December, but a bright twilight sky and clouds hid them. The sky was clear on Sunday, 5 December.

Mounted the iPhone 13 Pro Max on the 2" 30mm eyepiece to do afocal 81X imaging of some Messier Catalog open star clusters for my iPhone Messier Catalog photo album. These StarLock autoguided images were taken with the iOS app NightCap Camera (Long Exposure, Light Boost, ISO 32000, 1sec, 1 minute, 1X lens).





Then slewed to M1 (Crab Nebula) for this StarLock autoguided image with NightCap Camera (Long Exposure, Light Boost, ISO 32000, 1sec, 1 minute, 1X lens).
