Ngc5139- first light CFF RC250

What with weather, USB cable issues and ordering the the wrong focuser motor from starlight along with a trip overseas, getting a first light has been a long time coming.

Not the most challenging DSO but it’s great for picking up any collimation issues.


I havnt actually touched collimation yet, still trying to find a window of opportunity with decent seeing and it’s a little off, but straight out of the box, there don’t seem to be any dramas with the mirrors.
