This undesignated little region appeared to have quite a lot going on with it, with clear magnetic field lines and pores visible in white light. Taken with the Coronado SM90 double stacked with the Daystar Quark and the FLIR GH3 ICX916M camera using 2x2 binning to get a better scale for sampling.
Double stacking the SM90 with the Daystar Quark gave a high power high contrast view of the filament that was floating around in northern polar regions today.
Despite only being taken with 50mm aperture compared to the previous full disk which was taken at 90mm aperture, the higher contrast of the double stack setup makes details easier to see. The filament and active region really stand out in comparison to the single stack image, with proms also being nice and easy too. Taken with a Lunt50 etalon double stacked with a Daystar Quark on the 60mm f6 refractor, a 0.7x Baader solar telecompressor was used to reduce the image scale so that the full disk would fit on the chip of the FLIR GH3 ICX916M camera.
Lots of nice spicules and detail around the small active region in this full disk taken with the Coronado SM90 and FLIR GH3 ICX916M camera.
It was nice to do some CaK imaging on 5th of july as this seems to be a wavelength i've been neglecting of late. With all the tell tale signs of cycle 25 activity being visible at times this wavelength is excellent at picking up on these features. The seeing was reasonably good last friday morning, so I did a full disk with the 100mm Tal100R refractor at prime focus, f10 with the home brew CaK filter. The camera used was the FLIR Grasshopper 3 ICX916M. Lots of detail is visible in the full size image.
Calcium light is great for showing these turbulent regions of plage associated with old active regions. This particular one is a cycle 24 active region that formed on the equator way back in early spring, here in mid summer the remnants are clear to see. Taken with the 100mm Tal100R refractor, 3x barlow, home brew CaK filter and the FLIR Grasshopper 3 IMX174M camera.
A small emerging flux region had just passed over the solar limb in this image taken on July 5th. Scope used was the 100mm Tal100R refractor, 3x barlow lens, homebrew CaK filter and the GH3 IMX174M camera.
