Feb 15, 2015: Finally caught the dragon by its tail

[michael.h.f.wilkinson]

Some images I took today of the large filaprom. I used my SolarMax-II 60mm first with B1200 blocking filter and Daystar ERF and the DMK21AU618: 7 pane mosaic

I then used the BF5 blocking filter plus a Baader 35nm H-alpha filter to get rid of the IR leak it was showing. The image is a lot dimmer, requiring higher gain, but contrast seems better. Five pane mosaic:

I also caught some sunspots:

B1200+ERF

BF5 + 35nm H-alpha

Also got some full-disk mosaics (more of which later)

Interesting Michael

The BF5 images seem to be sharper and show more contrast than the BF12. Is this what you expected?

Very nice set of images

I have a feeling it is more a matter of contrast than actual sharpness. Maybe the ERF is causing some internal reflection and therefore glare. I will try to angle it to see if I can cut it.

Looking on Gong and Helioviewer the dragon is rapidly going round the corner, clear sky forecast here tomorrow for the first time in a while, hope it hangs on for a bit

It is still here. Might well be with us again tomorrow.

I wondered what it would look like when it finally got to the limb, very nicely captured.
