Hi All, I am new to this forum. I need suggestion on astro photography, since I will visit dark site soon. I have Canon 600d and Canon 10-18mm f4.5-5.6 wide angle lens. For capturing milky way or sky, I would keep my dslr in manual mode - bulb mode, timer as 30 secs or less to make sure there are no star trails, f5 is minimum at 10mm and ISO between 400 - 1600? What settings should I keep? Also, how many similar images, including subs and flats should I take to get a good image? The attached image is my second attempt to capture summer milky way.
