Today's Proms, HA, Sept 24th 2018

Heya, Some interesting proms on the limb this morning. Clear sky and decent seeing. Fall is approaching I suppose! Pointed my 120mm F8 refractor with a Quark at these ones. I think in general my 6" F8 just can't take the thermal load with currents in the tube with only the internal 50mm UV/IR cut fi...

Re: Return of the SPOD

I think having SPOD is great, and being able to look at an archive of past SPODs as time goes by would be really cool.

Re: Magnificent Prominence, HA, Sept 21 2018

Later today, that large proms is mostly gone, it's large frame is there, but it's way less bright and lost a lot of it's pressence. Opposite side of the disc, the other smaller prom has gotten more active and more interesting. I took a stab at it in much better seeing, with a smaller scope, the 120m...

What do you think is the most versatile high resolution solar telescope design?

Hey all, I'm curious what everyone thinks is the most versatile high resolution telescope design for solar imaging application. There are solar newtonians, SCT's and of course the refractor (for common air spaced and mirror designs). However, I'm curious about which design is ideal for different wav...

Magnificent Prominence, HA, Sept 21 2018

Heya, Woke up to a clear sky, but even more dreadful seeing than yesterday! I suppose all these cyclones off the coast are throwing turbulent air my way. I really can't wait for hurricane season to end and get back to my normal seeing. I can barely image at anything other than a medium scale (anythi...

Re: Today's Proms, Full Disc & Animations | HA | Sept 20th 2018

The time scale on that weird orb is less than a second. It continues all the way to the right edge, but I lost some of it due to writing buffer issues during that particular moment so I just kept the best uninterrupted chunk of frames that showed it. I see them sometimes. I'm used to seeing satelite...

Today's Proms, Full Disc & Animations | HA | Sept 20th 2018

Heya, Really poor seeing today. I struggled to get anything useful, even at smaller scale, the variable seeing was so rough I could barely do much with it. But, the sky was clear... so, I was tempted to just risk it and sweat away in the heat box to get something to look at. I rarely get an hour of ...

Re: Experimenting calcium imaging with small refractors

Heya, I've been using an ancient achromatic doublet, the old Celestron CR 150 HD (150mm F8) refractor for high resolution stuff (found this thing for $250). I've used it at full aperture and also at F10 (stopped down to about 120~127mm aperture). I generally use it at F10 because it's more appropria...

Beautiful Arching Prom Today! HA | Sept 19th 2018

Heya, Woke up to fairly yucky conditions, but later this morning there was a break in the clouds. Hot and humid, seeing was pretty bad, but figured I'd see if I could get lucky on a few frames. Turns out there's a lovely arching prominence right now. Celestron 150mm F8 Refractor + Baader UV/IR Cut +...

Today's Crazy Prom Forest! Plus Active Regions in HA & CaK | Sept 13th 2018

Heya, This morning looked clear for a moment, but the clouds were rolling in by 9:30am! Had to quickly get data, so I imaged at lower scales. The active regions are pretty calm, no visible umbra on anything. But the prom forest on the limb is amazing! Totally crazy, thick, and covering a huge chuck ...

Re: Sol from the 9th of September 2018.

Nice discs Eric!

The proms on your CaK discs, are those proms captured with the CaK PST filter mod you're using? Or are those from HA? If they're from your PST CaK filter mod, I'd love to know more!
