October 19th SOL H-alpha

[Peter Ward]

Been a wee-bit busy of late

...apologies for a slight gap in the data.

In case you were wondering: here is what the sun looked like today

[Larryp (Laurie)]

Great image, Peter

[EagleEyes (Andy)]

Wow! Amazing detail!

[Phil Hart]

jeepers.. that's (another) amazing sun image Peter.

Amazing!!! Peter, over what time period is the stack? Is it feasible to capture enough images through the day to animate that scene?

[ourkind (Carlos)]

Soho eat your heart out!

[Peter Ward]

Thanks Guys,

About 60 seconds Col. It's a 2 frame mosaic. Nothing to animate I'm afraid.

That said, yes you can get a sense of solar rotation and activity by bagging frames for the entire day. Particularly active proms and flares can change in a matter of minutes...but require high magnification and excellent seeing.

Nice work Pete. Still processing away on the 6 panel data even this morning. 2 panels would be sheer luxury.

That top prom has been there for a few days now and the one at 2 o'clock position looks like an eruptive prominence.

Are you still doing a separate run for the the proms or are you doing something different now?

Would be amazing to see, but I'd imagine a hell of lot of effort and data processing to pull off?

I have another (probably dumb) question. Would it make sense or improve things (given unlimited dollars) to capture this with a high res, high frame rate, high dynamic range cinema camera...like Red Epic? 5K 120fps seems tailor made for this?

Excellent solar disc!

Thanks Paul. If the proms are reasonably bright, a single run works fine.

Red make nice camera, but I am unaware of any mono chip models. The lack of a Bayer matrix with mono sensors effectively triples ( thereabouts) their resolution when compared to colour sensors used in Red or any other cameras, particularly when used with extremely monochromatic sources such as h-alpha, hence I'm not sure there I'd notice any improvement over a 2.7k mono camera I'm currently running.

A multi-day solar animation sequence would be a nice challenge...were it not for the weather

Now that is top stuff Peter! Lovely crisp detail and balance from the proms to the surface detail.

For a crazy amount of money, Red do have a mono sensor, recently released. They say it's 15-20% higher res than the colour sensor.

Hi Peter,

Fabulous image. Love the fine detail. Exquisite.

[Martin Pugh]

Super image Peter. You sure have solar imaging nailed.

cheers
Martin

[Moonman (Michael)]

That's a Woppa of a picture! The detail is amazing!

Ta. Actually, the original is double the web format...

Thanks Martin.... I could say the same about your deep-sky images, totally nailed them of late!

15-20% might be true with camera/cine lenses and extended objects. But with telescopes and point sources debayering loses much more.

As for the price tag..aye carrumba.....nah I'm not *that* keen.

Thanks Ted. Your excellent recent work has not gone un-noticed

[SkyViking (Rolf)]

Simply fantastic. That's a stunning solar image and superbly processed as usual. Well done.
