Helix Revisited
Tried to get some more data of the Helix Neb last night and set up around 9pm. A dozen 5 minute subs at ISO 1600 this time without the Teleview reducer.
My first time at combining images from more than 1 session and made harder by changing the scale of the image.
After these subs I had to perform a meridian flip and the 2 hours of data attained after that disappointed me with the object half out of the frame.
My modified 300D doesn't play with BYEOS and the LCD is fixed. When the target is straight up, I have no hope of determining if I have it framed properly. So only an hour of extra data in the 2nd image. The first image is almost 2 hours at ISO800 with the focal reducer fitted.
Oh well if nothing else I have learned to combine images from more than one session.
