Solar Polar Regions In Calcium Light - 5th July
These shots of the suns polar regions taken in calcium light shows the brighter polar faculae indicative of solar minimum conditions. Taken with the 100mm Tal100R refractor, 3x barlow and GH3 IMX174M camera have brought out some finer details.
Ex Active Regions In Ha - 5th July
The disturbed area above the filament is all that remains from the active regions that first appeared at the start of April. It is unlikely to be discernible in a few weeks time when it comes around the opposite limb, but is still worth checking for. Taken with the Coronado SM90 with the 3x barlow and the PGR GH3 IMX174M camera.
Ha Full Disk 5th July
Much pleased with the tuning I got on this full disk with the SM90 today, even across the field of view. Not much activity at this scale but a few features from cycle 24 on the celestial equator. Taken with the GH3 ICX916M camera.

Ha Full Disk 4th July
Much poorer conditions prevailed on thursday morning, with quite thick high cloud causing an increase in exposure time by a factor of 3, and also reducing contrast. Still, this allowed for an overview full disk to complement the views so far in the mornings of this week. Taken with the Coronado SM90 at prime focus and the FLIR GH3 ICX916M camera.
Flying To London Heathrow - 3rd July
Whilst taking my full disk shots I was pleased to see this transit of a British Airways flight heading from New York to London Heathrow. The nifty app 'Flightradar24' is excellent at highlighting what air traffic is around at an time and also produces the graphic image of the plane in question along with other information. This shot was taken with the Coronado SM90 double stacked with the Lunt50 etalon and used the FLIR GH3 ICX916M camera.
Northern Filament 3rd July
This small filament near the solar limb has significance as it sits aloft the magnetic boundary that marks the position of the sub surface solar jet stream that is associated with cycle 25 activity. Taken with the Coronado SM90 double stacked with a Daystar Quark to increase contrast by reducing continuum leakage in the Ha wing lines, the FLIR GH3 ICX916M camera was used.
Ex Active Regions 3rd July
The region of turbulent plasma that was associated with active regions that appeared in April still remains visible as some bright plage and filaments. Will it still be visible when it has a scheduled reappearance in about 3 weeks? Maybe? Taken with the Coronado SM90 double stacked with the Daystar Quark and the FLIR GH3 ICX916M camera.
