20141027 Sun, another observation on AR2192!

From that prominence loop on 20141015, this is the 4th observation/imaging session on AR2192!  This monster has grown to the size from slightly bigger than our Earth to now bigger than Jupiter.

All time in GMT+8.

Prime focus, taken at 1428:-

5x, taken at 1430:-

5x, taken at 1433:-

Taken at 1436 to 1441 all with 2x barlows, 12 frames stitched together, I guess the focuser draw tube slips a bit so that the lower left corner has a gap:-

 2x close up of a long filament taken at 1442:-

2x close up of AR2192, taken at 1443:-

I will try to do mosaic later, but the Tmax and RichView must be more carefully adjusted.
