Back from a week away on the boat, and Sunday dawned with clearish skies, bit of haze contributing to variable transparency. I got out the HaT to try with the Na Quark, but the seeing was not up to it so backed off to the 100mm Tal refractor. Initial impressions are it is like slightly more contrasty white light, but (at this scale) less of an emphasis on granule boundaries. It's interesting to see what this Q is capable of. Camera used throughout was the PGR Chameleon 3.
Bit of plage that has recently rotated into view...

Seeing was rapidly falling away so I dropped down to the 60mm f6 scope to do a full disk mosaic. I'm quite surprised at the detail I get from this small scope, especially when the image is viewed full size.

I've been trying the flat field function in firecapture too, which, as long as transparency (and exposure) remain the same is quite effective. Not sure if anyone else is using this?
