Visually saturdays prominences were great at the eyepiece on the Coronado SM90!
I got the opportunity on Saturday to test out a setup that i'd been wanting to use for a while with the FLIR GH3 ICX814 camera and the large chip it has. Using the 100mm Tal at 1000mm focal length allows me to still get the full disk on a single frame. The increased resolution of the 100mm means when the image is viewed full size both the spicule ring and also prominences are visible. There is a ghost image floating around in the bottom half of the frame that needs to be dealt with, but, on the whole i'm very pleased with this image.
I decided to try a shot of the departing active region in Sodium light. There was nothing to see apart from maybe 2 tiny pores. Taken with the 100mm Tal refractor and Sodium Quark along with the FLIR GH3 ICX 814 camera.
Prominences were the order of the day on Saturday; decaying AR12737 was approaching the limb, and apart from very small polar filaments the disk was essentially blank. All the action was on the limb though, with a number of prominences that visually were very impressive. Taken with a Lunt50 etalon on the Coronado SM90 and the FLIR GH3 ICX814 camera.
In a week this little active region started as an emerging flux region, developed into an active region with a number of small spots, and by now was decaying. This shot was taken as it approached the eastern limb with the SM90 double stacked with a daystar Quark. Seeing was far from ideal, and this image was by far the best of a number that was taken.
When I got up this morning the sun was blank, typical of solar minimum. However throughout the day an emerging flux region has rapidly developed into a crackling bipolar active region with 2 rapidly growing sunspots. It will be interesting to see how this develops more in the days ahead. Taken in the near ultraviolet in calcium wavelengths (393nm) with the 40mm f10 scope, 2x Cemax barlow, homebrew CaK filter and the FLIR GH3 ICX814 camera.
Sundays session also gave me a transit of this turbo prop going from Manchester to Jersey. There are only 3 frames where it is in shot so not much point of an animation. The seeing was awful too in the shorter wavelengths, but was nice to catch the surge prom from the active region in this image.
