Notes
Here we have five globulars in the Messier list: M3, M5, M13, M12 and M92 photographed on 28th April in one session. I thought it would be interesting to see them side-by-side. The transparency was good but yet again the seeing was poor which has affected the stars in the clusters which never reached a decent altitude. The image scale and rotation of each is identical. Each image has between 30 mins and one hour of exposure.
