AR2806, AR2807, Prominences | HA, CaK | March 5th 2021
Heya,
Had another clear morning with fair seeing. Seeing was around 1.2 arc-seconds to 1.5 arc-seconds for most of this, it barely supported the 120mm aperture, but I wanted to get moderate-high resolution captures of the two AR's while they were still around and active before going back to work. There's a rather large prominence off the limb near AR2806 and the opposite limb has a great eruptive surge prominence region that was pretty active all morning that is rounding the Eastern limb. Might be interesting soon.
PST etalon + double stacked 1.7A 8mm blocking filter tilted in a Skybender (thanks Apollo!) and 6A 5mm blocking filter.
B&W:
Colored:
Time Lapse Animations:
There's a surge prom on the limb erupting. This is 4.5 minutes of real time it changed so fast.
This animation is now on the front page of SpaceWeather for 3/5, woo!
Equipment:
120mm F10 masked achromatic doublet refractor
+ Baader Red CCD IR Block Filter (50mm, internal sub-aperture D-ERF)
+ Single PST Etalon
+ 1.7A HA 8mm blocking filter tilted in a Skybender (thanks Apollo!) double stacked with 6A HA 5mm blocking filter
+ IMX290 mono camera
60mm F16.7 masked achromatic doublet refractor
+ Lunt CaK B1200 module
+ IMX253 mono camera
Very best,

Excellent work Marty!! Clouds kept me from Ha but I did see that active area on the NE limb on the SDO images. See my post for today.
Outstanding animations!!

Marty your erupting surge prom on the limb is breath taking!
Fantastic work in both the photo and the gif!!!
The other photos are also excellent.
With 1.2 to 1.5 arc-seconds an 120mm works still so nicely?
Do you have the SSM graph with the violet photo moments at hand to upload?
Congratulations anyway!

1.2 arc seconds supports a 120mm aperture in 656nm (red) wavelengths, so it was able to get near critical sampling.
I actually didn't saves any graphs today, the seeing wasn't superb, but it wasn't violently bad either, my morning seeing generally supports 100~120mm aperture every morning. I originally had planned to test some more filter configurations and play with a full disc configuration but when I saw the surge prom and how 2806 had progressed, I put the big scope on there and just captured frames and went for "lucky imaging."
Very best,

Marty,
The NE active region shows up in CaK well too! I am also impressed how well the limb spicule layer shows up as well.
