November 13, 2018: More progress with astrophotography

Slowly, I'm overcoming problems - initially huge problems: vibration, tracking, noise and polar alignment.  For post processing, I'm using Deep Sky Stacker and then Lightroom 6 for post-post processing. Below are results from last night. Still room for improvement.

Orion Nebula, M42. 25 images stacked

Flame nebula (NGC2024) and the Horsehead Nebula (IC 434) - 46 images stacked (30 sec exposures)

October 31, 2018. Orion Nebula and flame nebula

More practice with astrophotography using DSLR camera telephoto lens.  I've encountered a new challenge - how to identify what I "think" I've photographed.  I've found a web site Astrometry: Images analysis and annotation. In addition, I've found that Amazon is offering an image and feature recognition site:  Amazon Image Recognition API.  This world of image analysis is a new world for me to explore.
