Just testing the SM60/PST Mod DS with a new focuser (to replace the Borg helical) Looks very promising.....
BUT, there's a bright active area visible near the centre of the solar disk - unexpected.
Nothing on Raben, but shows on the latest SOHO (just).
Well worth the look (and possible imaging - I've got terrible wind buffeting down here....) also check out the large filaprom...

Re: Active area visible???
Whoooo..........
Just got back from the workshop and had another look at the active area...hardly visible against the solar background .... and as I watched it brightened up dramatically definitely the brightest area on the disk - must have been a flare - looked like a very bright "halo" - I hope someone was imaging at 11:02 AEST....
Well worth watching - there may be some more interesting events to come......

I guess I imaged the very faint AR yesterday (visible in all wavelengths) Ken
