Re: Blank! Nothing to See Here... 21st may

Thanks Maurits, thanks Alexandra. It's exactly bright points like these we need to keep an eye on. They start off like this, as the solar jetstream for cycle 25 gets closer to the surface they become emerging flux regions, and then once the magnetic field strength gets above 1500 gauss we have spots...

There are yellow glass, red glass, Baader D-ERF, and Aries D-ERF that I'm aware of.
I've got a couple of Beloptik tri-bands, and Frederic at Airy Labs make a Ha ERF for C9.25.
