Saif and Nair Saif

[Mekon (Paul)]

Hello all, when I look at Orion on a star map one of the stars mentioned is Saiph. However my Celestron GOTO tells me to look for Nair Saiph. Are they the same thing?

TIA
(Please advise if this is the wrong forum.)

Hi Paul, No they are not the same Star
Saiph is Kappa Orionis RA 05.47.45 Dec=-09.40.11

Nair al Saif is another star in Orion RA =05.35.26 Dec=-05.54.36

I hope this helps
Cheers

Adding a few more details from the catalogs in CdC.

05h47m45.40s -09°40'11.0" * BSC 53 Kap Ori mV: 2.06 b-v:-0.17 sp: B0.5Ia HR:2004 HD:38771 Common name:Saiph
05h35m26.00s -05°54'36.0" * BSC 44 Iot Ori mV: 2.77 b-v:-0.24 sp: O9III HR:1899 HD:37043 Common name:Nair Al Saif

You can see these two stars each have at least five names, "Bright Star", "Bayer", "Harvard Revised" and "Henry Draper" catalogues and a common name.
