Hello .
I have a question about tilt and im not sure about what i found on the Web.
I have a new sharpstar 13028hnt and my stars are elongated all over the image . I think it's tilt because my backfocus seem to be ok . 55.6mm
My question is : does tilt affect the overall image quality or just the stars ? If the answer is just stars , i can live with that and use blurx
Thanks
It might be good to show an image of the elongation you are talking about; it's difficult to identify just from your words.
Tilt will affect your overall image quality.

This sounds more like guide error than a spacing issue.
I was just testing yesterday and forgot to save an exemple .
My guiding was good . Around 0.6
Still doesn’t sound like a spacing issue. No spikes anywhere in the guiding graph for the session. Have you blinked your frames? You could get a spike or two and still have a good RMS.
