Description

I attached the Nikon AF-S DX 40mm 1:2.8 lens to my CCD via the Geoptik adapter. Due to a small tilt in the setup it was not possible to have perfect focus over the whole frame. I took totally 12 frames each 300s, half focussed the upper part, the other half the lower part of the picture. Then I stiched the two useful halfs together. So the effective exposure time is only 30min.
