Here's my recent take on NGC1532. Captured over 5 nights from my home observatory in South Australia.
Telescope: Vixen VC200L with f6.4 reducer
Camera: DIY modded Canon 1000D with regulated peltier cooling @ 10C
Guiding: Lacerta OAG with QHY5L-II
Mount: Skywatcher NEQ6
Exposure details: 105 x 10mins @ ISO1600
I have pre-processed this using the new Pixinsight Bayer Drizzle feature. From the PI website: "The idea behind Bayer drizzle is pretty straightforward: with a sufficient number of dithered frames, the drizzle integration algorithm can be applied to fill the existing holes in the red, green and blue channels of multiple CFA Bayer images to form a demosaiced RGB color image directly from calibrated raw data without interpolation."
Using Aladin to cross-reference with the
NASA/IPAC Extragalactic Database indicates that there are ~540 galaxies within this field, including 110 galaxies at mag 20 or fainter.
