On Tuesday night 14th January 2019, I observed a 9th carbon star in Cassiopeia with my William Optics 158 mm F/7 apochromatic refractor. TYC 3651-650-1 is positioned near the optical double star STTA 251. I could not see it at 40X. But I was successful at 112X. It is so faint with a magnitude of 11.4. Its orange hue was evident at 140X, 167X, 225X and 280X. It is my 8th observed carbon star in Cassiopeia. My 79th overall. Can anyone tell me what its spectral class is? I would be delighted to know. Thank you very much.
There is a red star immediately to its northeast.Guide 9.1's designation is 3UC284-268448. Its magnitude is slightly brighter at 11.1. So all in all, it is quite a nice optical double less than 1 arc minute apart.
Clear skies from Aubrey.
