Diagnosis
I took some test images from my new dark sky site last night.
Guiding was a bit off - I have some balance to get right as my new rotator has added to the weight of the rig - I will need a new counterweight.
Collimation had looked quite good when adjusting it last week. But on 5 minutes subs (unbinned), I had eggy stars, particularly in the bottom left corner.
So here is an opportunity for armchair critics. Look at the attached material. Do I have a collimation issue, tilt in my imaging train or a combination of the 2?
The aberration image is taken using PI's Aberration Inspector script and shows images at full resolution of the extremities of the image and the centre. The other screenshot is from CCD Inspector.
Any thoughts?
Pete
