Tiger’s Eye Galaxy (NGC 2841 - UMa) A little tiger being chased by an old horse (TS140)
The ‘old horse’ in this case, is my TS140 scope. As I switched to the C8 EHD telescope recently, I have been neglecting my TS140 a bit. But last Monday, while my C8 was chasing M64, I aimed my TS140 on NGC 2841
The focal length is a bit short for this distant galaxy, so I took the same approach as with my M51 image on this scope earlier: BIN2. This gets me a bit closer, a bit of loss of resolution, but still sufficient to get some small detail in the galaxy. The Tiger’s Eye still remains quite small
It’s a very small tiger to catch, but I’ve seen a glimpse of its eye with this telescope. Maybe a revisit with a bigger telescope in the future …
NGC 2841 is an
unbarred spiral galaxy in the northern
circumpolar constellation of
Ursa Major. Initially thought to be about 30 million
light-years distant, a 2001
Hubble Space Telescope survey of the galaxy's
Cepheid variables determined its distance to be approximately 14.1
megaparsecs or 46 million light-years. The optical size of the galaxy is 8.′1 × 3.′5
This is the prototype for the
flocculent spiral galaxy, a type of spiral galaxy whose arms are patchy and discontinuous
