The first successful experiment with the Lunt LS50 telescope and Barlow. Barlow is nominally 2X but Barlow was at such a distance from the camera that here the odds are around 1.33.

Next I have to buy someone a 5X Barlow and try what it becomes. Now the Sun conveniently fills almost the entire camera area horizontally. In the vertical direction, the part is cut off but does not harm. The picture weakly shows Newton's rings, which are thus ge...
