Imaging tips
- NGC 3227 spans about 6.6′ × 5.0′, so frame it with a long focal length and a fine pixel scale, and plan many hours of broadband data.
- NGC 3226 lies about 2.2′ away, in the same field as the main galaxy.
- One imager used 8 h 5 min of LRGB on a 12 inch f/3.6 astrograph with a 1.17° field; NGC 3227, NGC 3226 and NGC 3222 all fitted.
- Another imager gathered 8 h 50 min through a 152 mm refractor over several nights in June.
- Best around February and March; it peaks near 60° altitude from 50°N.
