Comment : In the Southern direction there are so many galaxies, but it's very difficult for me to take photos in that direction, lot of things that block the view. In this photo the telescope is centered around the galaxy NGC 4435. But there are many more galaxies in the photo, the maximum exposure time I can get one night on a object in that direction is 40 minutes, needs much more.
