Messier 101

To fight the noise in the picture I did two things; Decrease the ISO value and simply take more frames. For this image I used 45(!) frames. By far the most frames I made for just one image. The total exposure time is almost 4 hours. The stacking was done with DeepSkyStacker. The final touch-up was done with Photoshop.

Messier 13 (again)

With the (already not so new anymore) modified Canon I had to have a go at Messier 13. This massiv globular cluster is one of the brightest in the sky. For this image I used two sets of images; one as general image; and one for the core - to prevent overexposure. In total the image has an eposure time of 90 minutes. I used the ISO1600 setting; a little over the top. The temperature outside is to high for this setting but who an I to complain :-)
