Caldwell 45 is a spiral galaxy ca. 70 million lightyears away, spread over 150 million ly. Magn. 11
The visible spiral arms are rich of new star forming regions (the little knots, best seen at high res.)

The very faint outer arms of this galaxy are not yet visible.
I need to add more light, perhabs using special filter, like Ha

thanks for watching !
