Dear willis,


唔好介意, 我用左你d相同太陽神作比較 http://www.hkastroforum.net/viewtopic.php?t=18804,
係器材方面既問題定係focus問題, 你d相比較out focus, 尤其係大陽左右兩側.

Dear Shan, thanks for ur comment. If it is out of focus, the whole disc will be out of focus. I guess there is a bit out of focus. But the bad edge performance of the disc is due to non-uniform illumination of solar scope. This happens in most solar scopes and this is the reason why doing solar mosaic difficult. Recently I find my solar images were bad and I doubt the main contribution is focusing. Give me sometime to figure it out.
