Hi folks!
-14° declination, not first choice for an central european astrophotographer. But I have never done a dwarf galaxy and so I had to take the chance to capture NGC6822 from my balcony. 15'x14' is large enough for the 80/480 APO. There is a lot of HII stuff in, so I took Ha too.
80/480 APO, MoravianG2-8300FW, 7x600s L, 6x600s for every channel in RGB and 9x900s Ha. Of course more time especially for luminance would be good, but the weather........ http://stargazerslounge.com/public/style_emoticons/default/classic/sad.gif
