Quote The veil nebula is quite large, much larger to fit in the frame with this configuration so I decided to give it a shot but only trying to photograph the west part of the nebula. With the AstroTrac I can only do about 2 hours worth of integration before the trac has to be "rewinded", so what I did was to simply frame the target perfectly (which took about 15-20 minutes), and then rewind the whole mount and start over. But because I had done the alignment before I only needed to "re-align" the RA-axis, which took only about two minutes. I'm really happy with the end-result. There is however a small hint of "red-ishness" visible in the background, which apparently is because of the severe light pollution of Munich. Quote
