20090707 Sun (AR1024)

Seeing 5/10, transparency 7/10. Tele Vue Ranger, DMK 31AF03.AS tracked by Meade LXD55. White light taken with APM Herschel Wedge, also with B+W ND3, (polarizer or green filter or 52mm aperture IR filter), H-alpha taken with Solarmax 40 with BF10.

1426 (GMT+8):-

1429 (GMT+8) with 5x:-

1439 (GMT+8), with green filter:-

1442 (GMT+8), without green filter:-
The one with IR pass is very bad, I guess IR is more affected by poor seeing... and maybe green is the least affected? The green filter really helped a lot to push the detail.
