[edit] How to find it

[edit] Appearance

This is very poor cluster, dominated by 6.8-mag quadriple star STF 446 (mags: 6.86, 9.9, 10.3 and 12.0)^[3]. Remaining stars are dimm, 12-mag to 14-mag, and are situated mainly NW from STF 446, less than 2' away.^[4]

[edit] Naked eye

The brightest star has visual magnitude of 6.8.

• NGC 1444 with 12x45 binoculars by Ante Perković (NOT SEEN, Jan 13 2003) [include this report]

[edit] Telescopes 71mm - 100mm (2.8" - 3.9"), binoculars 51mm - 70mm

[edit] Telescopes 101mm - 141mm (4" - 5.5"), binoculars 71mm - 100mm

[edit] Telescopes 101mm - 141mm (4" - 5.5")

In 120mm refractor, at 100x, just two brightest stars of STF 446 system (having magnitudes of 6.86 and 9.9, and separated 8.7") can be seen. Don't expect to see any signs of dimmer stars or nebulosity, at least not under 5.5-mag skies.^[5]

• NGC 1444 observation by Brian Rachford with 6" f/8 Newtonian (6 Dec 2002) [include this report]

[edit] Telescopes 178mm - 234mm (7" - 9.2")

In 8" telescope, at power between 110x and 130x, the rest of the cluster is barely visible. Group of faint stars is situated mainly NW of the central star, and appears very small (just 2') and very faint. It may require averted vision. Number of visible stars can vary significantly, from just around 6 (recoreded at LM=5.7)) to around 20 (LM=6.5).

The cluster has some recognisable features, like triangular shape and short row of 3 stars on the NW side. There is no concentration towards the central double.^{[6] [7][8]}

[edit] Telescopes 235mm - 305mm (9.25" - 12")

The cluster can be chalenging even in 10" telescope. Do not expect much more than what is seen in 8" telescope.^[9][10]

[edit] Notes

There are no significant DSOs in 2° area around NGC 1444 ^{see map:[4]}. The closest are open cluster King 7 (2.5° SE), bright nebula NGC 1491 (3.5° SE) and open cluster Czernik 16 (3° W).
