M52 Area and Bubble Nebula, NGC 7635
This picture features open cluster M52 and the Bubble Nebula, between Cepheus and Cassiopeia (the "M" in the northern milky way area). M52 is estimated to be anywhere from 3000 to 7000 light years from earth. M52 is visible as a dim, glowing patch in a finder scope or binoculars. From SEDS 52 Page, "Situated about 35' SW of M52 is the Bubble Nebula NGC 7635." Difficult to see visually, this is an interesting photographic object, which is probably the result of a star going nova.
The Cave Nebula is about 4 degrees away.
This is a combination of 18 x 4minute images night of 9/19/2006 at the HAS site. Canon EOS 20Da (unmodified), Takahashi TOA 130 (a 5" APO refractor), Losmandy G-11 mount. My current image processing workflow is here.
