Again my setup, but this time in a special edition, because of the upcoming transit of mercury. This is how I observe and photograph the sun. It's nothing speacial and not the best, but it works. For more details to this setup keep on reading. As you see I use my 5“ Newtonian and not my 10“ Schmidt-Cassegrain, because the focal length of the SC ist too big. I could buy a reducer, but with a larger filter it would get pretty expensive. And this setup works and I’m okay with that. On the tube is a Baader ND5 filter with a selfmade holder of cardboard. The filter just lets 1/100.000 of the sunlight through it. Between camera and telescope has to be a Barlow lens (in my case), because the focus is too deep in the focuser and my camera doesn’t reach it. But the Barlow gets the focus out of the focuser and I can focus with my camera. (So much focus) If I want to fix this, I have to buy a smaller focuser. So because of the Barlow I have again a big focal length and the sun is again to big for my camera sensor. But I just put to pieces of the sun together with Photoshop. Under the Barlow sits a moon filter (ND96) to darken the picture even more. Alternatively a colored filter for different contrasts. Yellow, orange and green are good in that case. I think I will get a little upgrade before the transit of Mercury on May, 9th. I hope there will be good weather on this day. #astronomy #astrophotography #nature #naturelovers #sun #mercury #transit #bresser #telescope
