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 (http://www.atscope.com.au/BRO/gallery201.html)

Great image, Peter:thumbsup:

[EagleEyes]

Wow! Amazing detail!

[Phil Hart]

:eyepop: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?

Soho eat your heart out! :thumbsup:

[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?

[colinmlegg]

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?

[Matt Wastell]

Excellent solar disc!

[Peter Ward]

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

[Peter Ward]

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 :question:

[Star Catcher]

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. :thumbsup::thumbsup:

Super image Peter. You sure have solar imaging nailed.

cheers

[Moonman]

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

[Peter Ward]

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! :thumbsup:



Thanks



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 :thumbsup:

[SkyViking]

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