Description: My first large mosaic with the QHY600. I had to crop some due to misalignment of the sensor, but didn't lose much. The full raw FITs file was 1.2GB! O3 filters are on indefinite back order so this will stay mono for a while, but I'm still very impressed with the scale and level of detail. SH2-240 The Spaghetti Nebula. This object is massive, spanning the width of 9 full moons in the sky, but so faint as to be very difficult to even image, let alone see.
