The region around the bubble nebula is full of Ha emission. If using an OSC camera, this region would be in all red. With the help of the Hubble palette, the color contrast of the image has been enhanced. We can see more detail of the bubble itself. It looks like it’s going to clean the “dust” around it. Fortunately, it didn’t clean all of them. Therefore, we still could enjoy the beauty of these nebulosity.

This is the first image taken by our new camera of SHCH observatory. We had upgraded from the 1-inch ASI533MM Pro to the APS-C format Touptek ATR2600M. With the huge improvement on the FOV, we can now collect more photons at the same time. In the aspect of selecting targets, we had much more choice. There is no need to use mosaic technique right now.
