Two and a half hours of data: H-alpha (1 hour), OIII (40 min) and SII (50 min) on the Tulip nebula captured with AstroDMx Capture through a William Optics 81mm APO refractor fitted with a ZWO EAF focuser, an 0.8 reducer/flattener, an Altair magnetic filter holder v2, a manual camera rotator and an SV605MC cooled monochrome, 14 bit CMOS camera. The equipment was mounted on a Celestron AVX mount. An SVBONY SV165 guide scope with a QHY-5II-M guide camera was used for guiding.
