NGC253
Object: NGC253
Spiral Galaxy
Const.: Sculptor
Camera: SXV-H9 Scope: Vixen R200SS Mount: Losmandy Titan
Filter(s): IR block Exposure: 29x4m TeleVue Paracorr
NGC253 - An edge-on spiral galaxy in Sculptor. A stack of 29 four minute exposures using a Vixen R200SS 8" f/4 Newtonian with a Paracorr coma corrector, shooting right through the light dome over NY City. The object was less than 30 degrees off the horizon. The individual exposures were calibrated, defect-corrected and stacked using AIP4WIN V2. This image has been resampled down from its original size.
