Re: Exploding arch prom from 9/19

That is a really cool sequence! The arch opens up and the tongue of plasma flicks through. Nice.

Re: Why is the PST etalon not sold on its own?

A friend saw my solar photos and asked me if he could use his iPhone with settings to do the same thing.
Yeah, he asked that.
So I created this instructional video for him:

Re: Prominence Hedgerow Animation

I'm looking into that, which is a helpful exercise. There were a lot of differences, including different capture time, t...

Closure of National Solar Observatory remains shrouded in secrecy

I have no idea what kind of security issue would require shut down of a solar observatory and post office. It'll probably all makes sense some day. SUNSPOT, New Mexico - The National Solar Observatory in Sunspot New Mexico has been closed since last Thursday. The post office near Sunspot also remain...

Re: First light with C8 Edge scope.

Great first shots, and an impressive imaging train! I can't wait to see more of your work.

Small spots and small proms today.

AR12712 on June 1

Active Region AR12712. Finally a sunny day! I was able to get some pretty good resolution on the Sun today and caught this sunspot region before it rotates off into the, errr, sunset. 2280mm focal length, 160mm refractor, LS80DSii module, Basler Ace http://a4.pbase.com/o10/77/857277/1/167579494.A9k7...
