Ha and Ca Sol

[Peter Ward]

Nice blue sky morning.

After positioning the telescope, SkyX's display was indicating the moon as remarkably close to the Sun today (in fact an annular eclipse in the USA)

Great detail Peter!

Ta. The Coronado 90mm etalon has served me well over the years.

When properly tuned they do not show a "hot spot" that is quite common with other designs (the disk overall illumination should look very even and only show limb darkening).

The only downside to solar imaging is daytime seeing...which at times makes the air look like it's boiling.

Good comparison of images Peter. Nice details. I agree - the atmosphere of Earth greatly affects solar imaging.
