| Telescope: | CN-212 Corrected Newtonian f/3.9 |
| Mount: | Losmandy G-11 |
| Imager: | ST-8XME Non-ABG CFW-10 Ha, SII, OIII Filters. |
| Image Details: |
Here it is, the final result of two night's of imaging: NGC 6888 color
using narrow band filters. Minimum image times were 5 minutes in length.
Longest images were 20 minutes. Darks, biases and flats were used on all
images. All images taken at -15C on the chip, ST-8xme non-ABG through CN212
corrected Newtonian mode. Images were stacked in MaxImDL, and saved.
They were then brought into Photoshop using FITS Liberator. Luminance
layering was used to generate the final stack.
