I have seen great photos taken with this chip that were composed from 30-minute subs. From closely inspecting your photograph, I believe you might have a CCD tilt that results in elongated and somehow blurred stars. But that is just my hardly educated guess...  |
Hi
Thanks for the comments, I'm aware of a potential tilt issue with the camera and I think this due to the adapter that FLI provided to convert the standard nosepiece of the MLx814 to ZTA. When attached to the camera it leaves a tiny gap between the adapter and the front plate of the camera and it is very difficult to see if that gap is uniform all the way round so I'm going to have a shim made to fill the gap and ensure uniformity all the way round. This is of course not an issue with the PL16803 as it has a purpose built ZTA front plate
Best wishes
Gordon
