AR2786 & AR2785 and Proms | Nov 24th 2020
Hey all,
AR2786 is still kicking up some great dust, well, plasma! Lots of surge prominences going on and some minor flaring, and some new proms have developed around the eastern limb. AR2785 is still towing it along and making a great pair. You can see AR2786's companion pore trailing it ever so slightly in the photosphere, looks like a neat dipole. Seeing was average to poor, was around 1.1 to 1.6 arc-seconds all morning unfortunately, so stayed in the 120mm aperture range. Wasn't able to get calcium at this scale in this seeing conditions unfortunately, had to stay in the red ranges. AR2786 has some gnarly plasma fingers going into it's nice big spot with a great big penumbra.
B&W:
Color:
Seeing Conditions:
Equipment:
120mm F10 Refractor
Baader Red CCD-IR Block Filter (Internal 2" D-ERF)
PST Etalon + 10mm HA BF (HA) + ASI290MM camera
10mm HA BF (WL) + ASI290MM camera
Very best,

The 4th and sixth images at first glance look like WL images but I noticed differences like the small bright spots around the sunspots, Ellerman bombs maybe which told me you are probably in the blue wing of hydrogen-alpha. Then I noticed the 656nm wavelength in your text confirming this. Nice capture Marty. I have never seen Ha capture spots quite this well!

They're mostly continuum in the image, but they were captured using just my 10mm HA blocking filter (5~7A bandpass, centered on 656nm). When I raise shadows hard, I can see spicules and proms on the limb, but very faint. Anyhow, this is the result of the blocking filter without an etalon, so basically a narrow HA filter but not narrow enough to stop out the light of the photosphere, so some features are gently merging.
Very best,

I really like the first picture, so much activity and like a giant whirlpool does the pseudo WL need a vertical flip though?

Re: AR2786 & AR2785 and Proms | Nov 24th 2020
Does it require any kind of filter before it like an ERF at the objective or a ND filter at the eyepiece? Would this work visually?MalVeauX wrote: ↑Wed Nov 25, 2020 11:17 amHi James,DeepSolar64 wrote: ↑Wed Nov 25, 2020 6:31 am The 4th and sixth images at first glance look like WL images but I noticed differences like the small bright spots around the sunspots, Ellerman bombs maybe which told me you are probably in the blue wing of hydrogen-alpha.
