What Size Curling Iron

solar observations with the 80ED

Finalmente dopo giorni di nuvole e pioggia I could try the filter on my astrosolar 80ED; was easy to build the whole, it was enough to paste the paper reduced the opening (60 mm) of the cap of the instrument, and after a few days the first light. I begin with the 28 mm, the disc appears to me opposed, and a nice bright white intense, just north east known a great spot, surrounded by a gray halo large enough, after a few seconds I get a nice group of three spots just below the equator, I decided to further investigation and mount the Orthoscopic by 12.5 mm, 48X. It stands out as the biggest stain, and another group known slowly a fourth component.
Try the new arrival, the Orthoscopic 6 mm Baader and, surprise, I find it quite comfortable, at least for bright objects.
It 's very very sharp, chromatic aberration is almost nil and the edges are much solar contrast, even though it is hard to find a point of optimum focus in this but I am meeting the fuocheggiatura micrometer.
In the group of spots you can see the fourth component very well.
I put the 12.5 mm and after a while I see you added a fifth member to the group.
After another little-known dark area at the north west, although it might well be a reflection of the eyepiece, I put the 6 mm and I realize that this is indeed another very small spot.
Hopefully the weather is nice too Tomorrow, during the eclipse of the sun.
