August 20, 2023: The first solar images in almost two months

[michael.h.f.wilkinson]

Finally managed to grab a load of solar data, for the first time since June 25, all with the trusty APM 80mm F/6, and Beloptik Tri-Band ERF. First up white light with a Lunt Herschel wedge and Baader Solar Continuum, and ASI178MM

Seeing was pretty decent allowing me to stack 40% of 2000 frames.

I then switched to the Lunt Ca-K module, and grabbed another 2000 frames.

Part-Inverted + pseudo-colour:

Clicking for full resolution is recommended. I also grabbed some H-alpha, but I will post these separately.

I've also got the Lunt Herschel wedge and use mine with a Baader polarising filter, does the Baader Solar Continuum make a difference?

I get a bit more contrast with the continuum filter. A regular green filter or even O-III also work

Excellent images. Hard to tell they are mosaics, nicely put together. Excellent details in the full images.

Thanks, but these are not the mosaics. The H-alpha ones in a separate post are
