Description

This is a quick first try on HaRGB with my DSLR.

Ha filter is mounted on the filter thread of the focal reducer, so it is not very close to the sensor, which I think is the main reason of the star halo.

Ha image and RGB image was taken one night apart, and the DSLR was in different rotation angle, so when processing I had to rotate the Ha image to align the images which was very hard to achieve, and still you can see some double stars on the edges. The solution is simpler than trying to align perfectly. Get a filter rack so I wont have to take the camera out to change the filter.

26x500s RGB 800 ISO

26x500s Ha 1600 ISO
