Leo Triplet (M66 Group)
The Leo Triplet is a small group of three interacting spiral galaxies located about 35 million light-years away. The gravitational interaction between these galaxies has created spectacular tidal tails and distorted structures.
Distance: 35 million light-years
Members: M65, M66, NGC 3628
Constellation: Leo
Group Members:
- M65: SA(s)a spiral, slightly tilted
- M66: SB(s)b barred spiral, largest member
- NGC 3628: Edge-on spiral with prominent dust lane
Key Features:
- Gravitational interaction visible in deep images
- NGC 3628 shows tidal tail extending 300,000 light-years
- All three visible in single wide-field frame
- Popular target for astrophotographers
Best Imaging Season: January - May
Optimal Integration: 15+ hours for tidal features
