The equipment used in that session: A 15 year-old 6CR achromat refractor (bought used) with re-spaced objective lens optimised for CAK imaging.

Re: Saturday Catch Up 9th March

The scudding clouds and haze made pulling the proms harder with the full disk, and despite only being 40mm f15 the softness of the image is a result of being onband in CaK imaging higher in the lower chromosphere. Those are beautiful images. Could you please explain why on-band CaK results in soft ...

Re: Coronal and prominence views from sea level

George,

Regarding the 10A Halpha image - I assume that without the occulting disk in place (for example - imaging with just a wedge) those loops would be totally washed out? What exposure did you use for this video?

Those are really amazing! The 10A Ha is quite interesting - do you by any chance have a comparison GONG image from the same time to compare with? I'm guessing from your comment above that those loops would not be seen in the GONG image??
