The Horsehead Nebula (Fall 2021)


OK, it's not like I've never taken an image of the Horsehead Nebula, but I haven't with this scope and camera.  This one took four nights and includes only frames east of the meridian (till the tree blocks the view). I was happy to capture signs of four or five Herbig-Haro objects identified in this paper.

This is 56x300" with the 203mm Synta ONTC Newtonian at f/4.95 with the Atikc 460EXC and an Astronomik CLS filter.
