M109

Hello,

this is M109 in Ursa Maior.

Imaged in March and April 2015 with the Moravian G2-8300 at my 12″ f/4 Newtonian with L:R:G:B=540:210:210:210 minutes. Subexposures were 30 minutes for luminance and 30 minutes for RGB.

In February 2014 I imaged the same galaxy with L:R:G:B=160:160:160:160 minutes. Subexposures were 10 minutes for luminance and 10 minutes for RGB.

So now I got a total exposure time of 30 hours.

M13 – The Great Globular Cluster in Hercules

Hello,

this is M13The Great Globular Cluster in Hercules
Imaged with the Moravian G2-8300 at my 12″ f/4 Newtonian with L:R:G:B=230:80:80:80 minutes. Subexposures were 10 minutes for luminance and 10 minutes for RGB and L:R:G:B=214:120:120:120 minutes. Subexposures were 2 minutes for luminance and 2 minutes for RGB.

So the total number of frames in this image is 335. So I processed 5.3 GB of data  with CCDStack, PixInsight, NAFE and Photoshop for this image.
