Description

This is a first light image for my SW 130P-DS.  I purchased this little inexpensive newtonian with the hope of it working as a faster alternative to my ED80 refractor.  I paired it with a Starizona Nexus 0.75 reducing coma corrector, and an ASI2600MM giving what for me is a wide field of 3.2 degrees, a focal length of 488mm and a fast focal ratio F3.75.  After initial adjustments indoors (removing a bit of tilt from the focuser, and basic collimation) the stars were sharp from the very first sub, no additional tweaks required.  

Comparing this version of M31 to my previous best effort shot with the ED-80, the detail captured by the 130P-DS is better, and the stars are free of any chromatic aberration.  So far the little newtonian looks to be a keeper.
