I just finished to work on the data of 2 weeks ago. The animation represent a close up portion of the Sun of 4 May. Images taken with a 100 ed refractor using a Daystar h-alpha filter at a focal of 2200mm, I reduced the focal do to a terrible seeing. I decided to follow for a couple of hours the NOAA 1734 zone, the bigger one of the week with the hope to catch a big X flares like the yeasterday one. Even if the seeing and the video compression had blured alot of details, the filaments and spicules movements are evident, also a couple of mini flares are visible during the time-lapse. Hope in bigger one next time. The mosaic instead was captured the last weekend at the same focal of 2200, 6 images at different exposure for disc and proms (click on it for the zoom). I also captured a serie of movies to assemble a time-lapse of the prominence, but still on working.
While I was exploring the Sun disc looking for a good subject I found this small active zone next the limb, that was erupting, I decided to follow its fast closure with short captures, infact after only 10 minutes the event was ended. To build the movie then I added a second surge prominence I captured few months ago. As you can see also from the Earth scale, the sujects this time are very small events, like micro surge, spicules eruption, all watchable only on the edge of the disc with very fast capture and lower exposure respect to the filming of normal prominence. Usually they are burn and overexposed losing any details. You can also see plasma falling from the other side of the Sun. YouTube compression blur many of the details but I hope you will like it.

After few days of rain and storms the weekend of 4th was clear with only few small clouds passing through. The seeing was average and with a Sun with so many prominence (my favorite subject) i couldn't resist and spent several hours of saturday and sunday imaging. I just finished to work at the data, in the clip you will find the best prominence captures and a timelapse of the huge one, which keep us entertained for two long days. I suggest to see the HD version to better enjoy the spicules details. Hope you like it, all captured at 3 - 3.5 meter. Video HD The presence of few promninence next the bigger one suggested to make a big mosaic (3500px) of the big system. Full resolution Here few of the images, you can find all of them also in colored version on Flickr Full resolution An huge tornado Full resolution Full resolution In the afternoon I also run at the neighbour town to capture a fast ISS transit.
