20240623 - Solex

Published: 08 July 2024

Almost the last day of my hols and the last day of imaging.

A better day than the previous in terms of seeing and my competence.

First, Ha

Not as sharp as it could be but the prominences show up remarkably well

Calcium K - quite pleased with this, it appears to be sharp and there is very good definition.

and finally, Hydrogen Beta

I think that the bands occur when the line is selected using SharpCap. Broadly, the line is selected by drawing a box around the spectral line. I think that my problem here is that the box is too deep and that is causing the banding effect. I'll need to experiment further.
