Sun in HAlpha /White Light With Lunt LS100THa / ES AR152 + Baader Wedge Uploaded 9/2/12 Weekend Report For the weekend of September 1-2, 2012
Images below are 800-1290 wide and non clickable


Lets start with the white light images, taken with the six inch AR152 at prime focus. A Baader Continuum filter + UV/IR blocker was used with the DMK51 camera for these images. The prominent spot group seen here is AR1560, a very active region that is evolving rapidly in appearance.

next we inserted the 2.5x Televue Powermate Barlow. This brings up the white light granulation quite a bit, and we can now zoom in on the individual spot groups. On the Eastern Limb we find AR1564, a very active region with tons of tiny spots:

Next, we look at the big spot chain, AR1560.

Now for the 5x Barlow for a maximum view. The aperture is only 4 inches here, since the seeing will not always allow a full six inches.

On the West limb we find the departing group AR1553:

AR1564 on the east limb has many tiny pores inside, which are sunspots with no penumbra on their outside.

And of course the star of the show this weekend, AR1560:

Now lets show some hydrogen alpha images taken with the Lunt 100. Prime focus shows the entire disk at once.

Now for a few 2.5x close ups of some of the active regions. The center of the disk is AR1560:

On the eastern limb, we can see the action. Much more to see in Hydrogen light:

The western limb is also full of activity:

Now by overexposing the limb, we can see the prominences, sheets of plasma extending beyond the limb of the sun. I have blacked out the greatly overexposed disk of the sun as to not be a distraction:

Well, thats it for this weekend. Hope you enjoyed our Sun!
