Thanks all, :bow :bow BTW. My company is ARIES, not Aires. :) Valery Apologies, I've corrected it. :) Question: Would you mind please seeing your PM either here on SolarChat or CloudyNights from me? Trying to get the most out of the D-ERF, just need some information. If they're not coming through, I...

Thanks all, Later in the afternoon, it was still clear, so I figured I'd try to do some time lapse animation and grabbed data for an hour. Was mostly interested in the main filament in the active region to see it's plasma flowing around and of course any potential flare activity crackling in the pla...

Heya, It's been raining for days and total cloud cover all through this week, but today it was cleared up for a while. Seeing was poor this morning. But I was able to get a little time on AR2752 which is still persistent. I looked at the photosphere and didn't notice any appreciable sunspot, but the...

Thanks all, appreciate it, I'm glad we all got to see such a transit. For many it's the last!

Very best,

Great captures Stu, always love to see some Calcium!

Very best,

Great show of the transit Pedro!

Very best,

Super captures Phil!

Very best,

Lovely Predro, really starkly different only just 2 years ago how much more active the star was!

Very best,

Hey all, I was lucky to have decent weather all day for once, right up to the end, it clouded up at the end of the transit but I was still able to grab some information there through clouds and poor seeing. But up to that point it was a wonderful day of observing and I imaged a little bit along the ...

Depends on the weather entirely.

Very best,

Super cool Phil! Never would have guessed an 80mm!

Very best,

Hi Valery, Would you kindly check out my PM to you on here? I think the etalon on the left is probably better. My reasons: It's nearly the same as the one on the right, at F42, yet it's doing it at F30. So if they were both brought to F42, the one on the left would be superior and more narrow. I'm s...

Thanks all :bow Marty, is the first image in WL done with a wedge or with film filter? I don't use film nor wedges for imaging, they lower transmission too much. That first image was done with my C8 Edge and my full aperture Aires D-ERF followed by a Baader Red CCD-IR blocked filter (2nd erf). The t...

Heya, Woke up to an ok sky, clouds, but had a chance. Got some data later in the afternoon, so seeing was poor, but managed. The new plage is interesting and there are some proms in the quadrants on the limbs. Took at look at the plage in two scales and both from the chromosphere & photosphere persp...

Heya,

Well, use a 656nm (Astronomik HA 12nm) filter for poor seeing.
Use a 395nm or 430nm (Andover or Edmund Optics) for higher angular resolution with very good seeing.

Very best,

Thanks all!

It became an interesting prom on the limb since then!

Very best,

Heya, Woke up to a fairly clear sky, it's been storming for days with the remnants of the tropical storm that just finished up in the Gulf of Mexico. Not much going on today on our star, but a fairly interesting and dark filament, doesn't look like much at course scale, but at fine scale it reveals ...

Lovely discs Eric!

Very best,

Lovely captures Pedro!

Very best,

Lovely captures Brian!

Very best,

Lovely discs Mark!

Very best,

Thanks, I am very interested to see more info on this. I too am quite interested in adding the Baader 1.25x GPC and how it can be easily added to the imaging train to operate a 150mm F10 option from time to time. Especially from a thermal handling standpoint, as my 120mm F10 version handles the heat...
