Helix is testing my camera and cheap filter

Hi All,

Have been for a while trying to image Helix Planetary Nebula and without the CLS filter from SVBony, the maximum subs I could try was 90sec.

Now with the filter depending on the moon, yesterday I managed to get 300sec subs although my guide camera is in need of replacement.

A lot of subs had to be removed as the webcam just can't handle the guide quality. Anyway, there are 2 images the first is from guided ~ 50 x 300sec, while the second is from 104 x combination 240sec (from earlier) and 300sec. The thermal noise level of the camera (450D) is starting to suffer and therefore have to clip the background to compensate.

Overall for such an old camera, it is performing well under the circumstances.

The filter is definitely impeding the yellow, and very difficult to get the yellow stars to pop. I hope to try to change camera settings later to compensate hopefully.

Enjoy
