Notes |
This was my first attempt at H-Alpha DSLR imaging. A new area of expertise. I was unsure of how much exposure this might need and also how long the subs needed to be. I'm very happy with this result and it is quite obvious that I captured enough data. However, this poses a new processing challenge for me so I might process this one again later for a different result. I gave a friend of mine access to the data at his request so we could combine it with a color image he took through his new Takahashi E130D Astrograph. That image with image details are listed below. |
