20250517 Sun (reducer finally works)

This is a test of equipment, a 1.25" 0.5x focal reducer.  It won't come to focus before, but then I remember that I have a very short 1.25" nosepiece for C mount.  It comes to focus finally.

It's easy to take a full disc shots now!  Maybe good for continuous monitoring, like making animations, I shall try later.


This is a simple two frames mosaic at prime focus.  The non-uniform illumination makes it a bit tricky, but this does not worth the effort now.


Close up with AR4087, with 2x barlows.

Solar imaging is happy in Scottish summer.
