Super-mega-hi-res AR1045 – a river of light

[Dennis]

Hello,

Sheltering under my shade blanket from the fierce heat and glare of the Sun, I watched in awe as waves of good seeing washed over the live image on the computer screen, revealing some breathtaking moments of steady seeing that lasted several seconds at a time. This one AVI was going to be a joy to process.:)

By the time I had slewed to AR1046, the seeing had slumped from gobsmackingly fantastic to just very good. I went to fetch the x2.5 PowerMate but upon returning, the Sun was blotted out by wisps of clouds arriving from the SE, so I packed up. Plugging the portable HDD into my desktop computer I eagerly launched AviStack, itching to see the quality of the data embedded in the 1250 frame file; I wasn’t disappointed, it was easily the best of the 3 recorded today.

In the final image we can see the remnants of AR1045 along with solar granules and faculae, bright areas that are usually most easily seen near the limb of the solar disk. I’m not sure if it’s just a perspective effect, but the main sun spot appears to have the profile of a depression, or bowl?

Cheers

That's fantastic Dennis. Amazing landscape of the sun's surface.
:thumbsup:

That's excellent Dennis! You're certainly getting the goods out of Avistack! I love the 3D/perspective look of this image too.

Wow Dennis, another image for Spaceweather.com.

Any truth to the rumour that they are being petitioned to rename their site "Dennis's Spaceweather"?:D

Awesome Dennis, good to see some activity on sol!

[Troy]

Nice picture Dennis

Great hi-res. Never had that quality of seeing from here in 2 years solar imaging, very envious. I’ve also noticed that sunspots nearing the limb appear slightly sunken.

Fanastic work. Well done - gives the pro's a run for their money. The depth of field is simply stunning!

[h0ughy]

oh how good is that........... awesome mr simmons.

[Gladiator]

Magnificent vista, Dennis!
I'm also loving the way you framed the river! :thumbsup:

[Octane]

Dennis,

That's remarkable.

The texture is almost hypnotising.

Also, agree with what looks like a depression; like water flowing into a sinkhole.

I rarely ever visit this sub-forum; I'm sure glad I did.

Thank you to everyone for your nice words about this image, although please excuse the somewhat childish title of this post – I was a little excited at the time!;)

I guess that one day I had to get lucky with Sol, after innumerable times setting up over the last couple of years, each time being thwarted by either mediocre seeing or pesky clouds that seem to boil up from nowhere at the first glimpse of a telescope being deployed!:(

Good seeing doth good data make!:)

Cheers

Hey Dennis
That is a cracker of an image - I know you put in a fair bit of time and you are getting some great rewards!
Super sweet!

[Dennis]

Thanks Matt. My best hi-res shots have come through playing the waiting game. I watch the “seeing” on the notebook display and when it settles down, start the capture and hope that the AVI run records sufficient bursts of good seeing to produce enough good data to stack.

Now if only someone would invent some “seeing software” that monitors the seeing in real time and starts/pauses the recording accordingly.

I’ve spent way too many hours trolling through AVI’s looking for the good ‘uns!

Cheers

Dennis

Beautiful work Dennis... Really amazing... I've just got to get me a solar filter.. :)

[iceman]

Beautiful Dennis, the perspective is just awesome. Lovely and sharp, right place at the right time with the right skills!

[Miaplacidus]

One hell of a Shazam-esque image there, Dennis. And beautifully framed. Congratulations.

(A colleague here just said: "Hey, that is hot!")

Thank you again for the most recent nice words about my AR1045 image.

When I posted it on CN, someone replied that the depression like appearance of the large sun spot near the limb is termed the “Wilson Effect”.

The apparent displacement of a sunspot's umbra towards the Sun's centre as the spot approaches the limb was named after the Scottish astronomer Alexander Wilson (1714–86), who first observed it in 1769.

Cheers
