Partial Solar Eclipse through the Baader-U filter

[Nico]

Since nobody else has shared any UV images of the solar eclipse form 20 March 2015 I thought I do: All images were taken with an unmodified Panasonic Lumix GH2, with the Panasonic 100-300 mm, f 4,5 -5,6 at 300 mm, through a Baader U-filter. The white balance was automatic and not corrected. The reason for using the Baader U was to reduce the incoming light to a reasonable level and it was the strongest filter I had available … With no previous experience with solar photography this was the most reasonable thing I could figure out in a rush.

You were *way* luckier than many of us only observing slate grey blanketing clouds :D Fortunately I observed the Total Eclipse of 1954 and several near-total ones later, so I can wait until next opportunity in 2017.

 

Yes, the Baader U truly is a 'dense' filter outside its designating bandpass range. Given the itensity of the sun I'm not surprised of the results you present here. Flare and ghosts are what one would expect for ma multi-element lens pointed at the sun as well. Doesn't detract too much anyway.

What a cool series! Very interesting, Nico. Thanks so much for posting this.

The sunspot shows up well in UV.

Beautiful pictures of really good quality!

 

Even my simple and old Pentax 200mm f4 with 6 Elements in 5 Groups suffers from flares and ghosts when pointing at the sun.

 

The effects decreased when I removed the solid (welding glass) filter and put foils on.

 

Seems at least in my case a lot of ghosting was caused by the filter under that extreme conditions.
