Thanks so much! And thanks for the tip on the F-ratio. Heres another one i did 5 nights earlier (which means i got it backwards and this is really my first ever piggyback shot) only with my OM2n and a 28mm wide angle @ f4. The film was Kodak Elitechrome 400. Not much abberition as the 50mm f1.8. I think i like the Elitechrome 400 a little better. It required very little curves adjusting to the raw TIFF as it was pretty evenly dark blue. However since this was really my first attempt at guiding too, my stars are a little bloated. My drift alignment was not so good as on March 23rd and it was really windy. Mount was all over the place. I now see first hand the importance of a good drift polar alignment. My unguided shot with a larger lens with has much less bloating than my guided shot here.
I love this hobby.
