Galaxy time

M101 M51 and the Needle Galaxy from the last few weeks. It's been difficult at times with strong winds and snow showers to contend with but having got my guiding sorted out it is now much easier to get longer exposures and gain more data for the final images. M101 was done with my 450d ISO 1600 4 minute subs about 4 hours worth. M51 5 minute subs one hour's worth and last night the Needle Galaxy two-minute subs about 30 of them. One of the most useful discoveries of late is using dithering with my images something I never really tried before but it really makes a big difference to the final stacked image so well worth trying it out.
