Description

This is first light with the Takahashi CR 0.73x reducer for my TAK FSQ106 EDX4. In combination with my APS/C size sensor, it gives a Field of View of more the 2 degrees with an image scale of 2 arcsec/pixel, ideal to image large target as the Andromeda galaxy at F/3.65. I am still strangling with a small spherical aberration and radial stars in the corner but since they are symmetrical I can live with it :-)

The data was acquired during several days, 2-3 hours per night due to my limited visibility to the west when the target crosses the meridian. 

I hope I will manage to add additional Ha data in the next few days.
