Re: Sol from the 4th of June 2018.

Thanks, Eric. I was curious to see what SDO recorded at the same time.

I believe it is a real feature, rather than an image artefact. Maybe it's the result of some random alignment, or maybe it was nucleated at AR12712.

Thoughts anyone?

Mark, Did you capture another sodium bridge??

It's so difficult to distinguish if these are real features, or a trick of the eye. It's interesting to note, though, that this feature does appear to connect between two pores.

Re: Sol from the 4th of June 2018.

Alexandra and guys, thanks for the comments. Stu, I also saw that. BTW, you can see it in all the FD´s in CaK and in Ha, in some shots it looks much fainter. In my workflow I always change the recording parameters on each FD, so that is why in some FD`s you can see more or less details. The seam co...

Ha Filaprom June 11th

Just time for a 'quick' solar image this evening after work. I say 'quick' because by the time I've lugged all of my gear around the house to my back garden it feels like much longer than the few minutes that it actually takes, going back and forth, taking a few pieces at a time. Anyhow, moments aft...

Re: Sol from the 4th of June 2018.

Excellent images, as always, Eric; lots of contrast and detail.

There appears to be a 'seam' around the Sun in the third (and inverted fourth) image. Is this some sort of long range structure, I wonder?

Re: Sundays Sodium Sun - 3rd June

Good images, there, Mark. The sodium Quark looks like a nice addition to the family. I've no idea what the arches are. You'll have to see if they show up in future images using the same setup to check if they are some sort of artefact, although looking closely there appears to be lots of similar arc...

Re: Sunday Sun 3rd June_RCT_Ha

Interesting setup, I'm curious about how to rear-mount fast focal-ratio etalons behind larger scopes, be they SCT or refractor (though mainly interested in SCT at the larger apertures for compactness and weight). Especially finding a way to use a 50mm or 60mm etalon, instead of a PST etalon to avoi...

Re: Sunday Sun 3rd June_RCT_Ha

Hi Stu, The result is clearly better than all before! Nice processing too. I noted that you do use some oversampling. The image scale you do use with a 10" scope is significatly larger than I do use with my 11" scope. Smaller scale will makes imaging easier - shorter exposure, larger FOV, better se...

Re: Sunday Sun 3rd June_RCT_Ha

Many thanks everyone for your kind comments. Like all these things, practice and homing in on things that work are what count.....and I'm still learning! AR2712 is/was a particularly spectacular target with loads of dramatic structures on a large scale.

Re: Sunspot AR2712, some flaring, today's proms | Quark | June 2nd 2018

Very nice, Marty. Lots of great detail in both the AR and proms. It's a blue sky start to the day here, so I'm hoping to have a good session too. I'll see what the atmosphere is doing!

Flares are always exciting to see 'live'. Hopefully there's still some activity this morning.
