Description

The computer and stock focuser were broken early this summer on my Takahashi FSQ-85EDX rig. I replaced the Feather Touch focuser and decided to use ASI Air Plus to control the rig four weeks ago. I really like my new setup. This is a Hubble Palette (SHO) narrowband imaging with RGB stars. C & C are welcome.
