My adventure with astrophotography is going quite well except that I'm a dusk and dawn target for mosquitoes. Tracking is improving. Vibration control is improving. here is the Orion Nebula - cropped and uncropped.
|Orion Nebula uncrossed: ISO 8000 Exposure, 10 sec 400 mm|
|Cropped: ISO 3200, 5 sec, 400 mm|
Oct 5 Better tracking ISO 800 60 sec exposure, 200mm
The boundary around the reddish region is quite interesting. The colors apparently come from UV radiation of hydrogen gas (ionized Hydrogen, H II)
