Thanks Chris.

Yeah I thought the satellite trails would go as well in median combine bit not in this case. I did not do data reject on this image. I may go back and use it. I usually do data reject but I was wondering if it also makes data less sharp as the interpolation process after removal of rejects possibly could do that.

Eggy stars are slightly wrong adapter distance. Unfortunately I have 2 adapters with 2 extension pieces so I can use both Proline and microline camera. I need to label them more exactly as I was not sure which combo went with which camera in the end. I tried several combos. This seemed best but is not the right one. The right combo gives perfect stars to the corner but the downside of this wonderful AP reducer/corrector is it requires accuracy to +/- 1mm. So no tolerance for error.

Thanks Steve. Top half looks a but yellow perhaps? I took that as a thin layer of dust. I have seen FSQ images of this area and the dust is very extensive. I'll check it though. Thanks.
