Based on a really good video from Jenhams Astronomy, and using 'Transit-finder.com' I took this video using my 127mm Mak and a DSLR early one morning whilst in Spain. The Sun was only a few degrees above the horizon, so the 'seeing' was really bad, but focus is ok. I have another one forecast for this Friday from close to my home location, if the sun is visible!
