Our star is buzzing with activity at the moment - just as I started imaging today 3 active regions started minor flaring pretty much simultaneously following the major M class flare from AR1429 earlier in the day. Hopefully be able to get somemore shots in in the evenings ahead if skies stay clear!

Ha Full Disk - 3rd March
Absolutely loads of interesting things going on in this hydrogen alpha image! The mini-erf has been removed on the coronado BF10 but when replaced with a Baader neodymium filter contrast increases significantly but keeps the exposure short. Not entirely sure what is going on here - my theory is that without the mini ERF there is some IR leak, and with the neodymium in place this is blocked. Whatever the reason this looks like will be a permanent feature on my ha solar setup!
CaK Full Disk - 3rd March
Whilst the sun in white light may be quiet, there is always plenty to see at CaK wavelengths. This image was generated using autostakkert, while I like the results from it I do say i prefer avistack2 for its ability to handle batches of files, and also to be able to apply flats and darks to an image. Taken with the 70mm frac @ f9, Baader-Nado homebrew filter, 6 pane mosaic assembled using photomerge in CS4. All sharpening was done using Iterative Unsharp Mask. Not a wavelet in sight...
White Light Full Disk - 3rd march
taken with the 70mm frac @ f11, 705nm TiO2 filter, Lunt wedge and DMK31 camera. This is a 6 pane mosaic assembled in Imerge...
AR1429 - 3rd March
First views of behemoth spot forming part of AR1429. This one is going to be very active over the next couple of weeks!
