A couple of images

Messier 3 and Messier 13

Images captured using Altair Hypercam 183c pro connected to Skywatcher 150p on EQ3-2 mount guided using asi120mm and phd2. Images captured using APT stacked in DSS and processed in Pixinsight. Each image is 30 x 60 sec exposures with darks, flats and dark flats calibration frames added.

Is the scale of these two superb pictures the same? It would be perhaps interesting to assemble and compare these with some of the the other "bright" globular clusters on the Messier list, M2, M5, M10, M12, M15, M22, & M92, say: all at the same scale. Regards maf.

Hi

Yes both images taken with the same set up on the same evening so in scale. Nice idea.
