It was a busy weekend these past couple of days with friends stopping, late night chit chatting meant I wasn't up at my usual 'crack of dawn' weekend timings for the sunshine, and so was rushing to get the solar in. I'd imaged (even briefer) on Saturday morning and the seeing was surprisingly good, so I gambled Sunday might be on a par, it wasn't, it was worse, but not by a huge amount, so I just upped the number of frames being captured on the rationale that some of the frames would be good. It kind of did, but at the expense of huge amounts of data to chew through!
Starting off with the disks for the overview, the Ha wasn't shot until much later in the afternoon, the CaK was shot in the morning. Ha with the DS50 Lunt etalons, 2x cemax zwo183mm. CaK 40mm f15 with the zwo183mm.

I opted for closeups with 80mm f15 with the 2x cemax and zwo290mm in CaK, for Ha, and providing much the same resolution the 152mm f6 stopped down to 120mm to get to f7.5, throw in the 4x telecentric and the solar spectrum 0.3a sees f30, all recorded with the imx174 chipped FLIR camera. There are more CaK than Ha, I shot the CaK first, and by the time the Ha came along the seeing was failing and my hard drive filling...

Note the fibrils coming out of some of the larger sunspots in CaK, they definitely have 'height' to them unlike in WL, kind of reminds me of tentacles from a sea anenome... Guess we are seeing up into the chromosphere...
Hope you like them.
