A small break in the weather finally allowed me to complete my M33. The difference from my first attempt with only 15 RGB frames [https://flic.kr/p/2qqnCQH] is really amazing.
- Taken from a Bortle 5 suburban back yard.
- Takahashi FSQ-106EDX4 at f/5.
- SBIG ST-8300M at 1×1 binning, with the FW5-8300 5 position filter wheel.
- IDAS LPS-D3 36mm unmounted filter for luminance and Astronomik Deep-Sky 36mm unmounted RGB filters.
- Losmady G11 Gemini 2, guided with a piggybacked AstroTech 65EDQ and an Orion StarShoot autoguider.
- Software included PHD2 for guiding, Sequence Generator Pro for acquisition, and PixInsight for image processing.
- 70 x 600s luminance integrations (IDAS LPS-D3)
- 45 x 600s each red, green and blue filters
Total exposure time of 34 hours.
