After just, just under 48 hours of total exposure time, my image of the M33 Triangulum Galaxy is finally done. As with the M31 Andromeda Galaxy image, I opted to capture separate Hydrogen-Alpha data to enhance the Red channel of the image. This has brought out the most active regions within the galaxy in vivid detail. Below is the final image after all post-processing:
The NGC7293 Helix Nebula is a very interesting and pretty large planetary nebula located towards the South. Given Spain's latitude, it can be imaged within a window of about two months of the year, though it is still fairly low in altitude above horizon throughout. I tended to start imaging this target when it was 18° above horizon, and ended before it dipped to the same altitude above horizon later in the night. My initial plan was to do this in the Hubble Palette, but between the weeks passing and the Moon disappearing later in the night, the window to image this target was soon closing. I therefore cut my imaging run short of capturing any Sulphur-II data.
