M-class flare animation (90 mm)

[GreatAttractor]

It was a fruitful (and too hot) Saturday morning with good seeing. Everything captured with Chameleon 3 mono (ICX445), stacked in AviStack 2, post-processed and aligned with ImPPG, colored in GIMP.

Mandatory full disc with Lunt 35:

Lunt 35 90 mm mod, mosaics stitched in MS ICE:

And finally, animation of the M1.3 flare at AR 2360 (maximum at 7:29 UT). 30-second intervals, shortened to 15 seconds around the maximum. Total: 1:23 h. Shutter time was reduced on two occassions during capture.

On closer inspection there is a long, faint arc entering the sunspot shortly before the flare's maximum.

Very nice. That AR has been very busy of late.

I'm impressed.

For the ignorant, have you used only the Lunt scope or is this with the narrow band filter as well? Just wondering the bandwidth required for this detail.

My budget can't stretch that far but I can dream....

[David Smith]

Impressive.

Thank you, everyone.

I've used the Lunt 35, which includes a 0.7 Å Hα filter (etalon) as its main component. For high-resolution shots I'm using a 100 mm (90 mm effective) refractor modified to accept the LS35 etalon as an attachment. Details are available here: http://solarchat.natca.net/viewtopic.php?f=9&t=13382

Really good detail in those shots

Excellent images, I was watching AR2360 flaring away on GONG hoping the clouds would clear

Thanks, just the information I wanted.

The animation brings it all to life.

Bravo! It's a beautiful flare.

Very nice capture, I am wondering if that's what I caught today.
