Good day to you all.
I did set up my William Optics 158 mm F/7 apochromatic refractor in my back garden on Saturday night 19th September 2020 under a Bortle 9 sky.
The sky was very clear with no Moon visible as I was seeking out some double stars in the WZ Cassiopeiae area.
We all love observing the strong bright rich orange carbon star WZ Cas itself with its blue-white companion SAO 21006 quite close by. Do we not?
But I was aiming to seek out a very challenging faint carbon star which has the designation Case 271 or, as my Guide 9.1 DVD calls it, 3UC302-001937 which is about 1 degree away.
Simbad had drawn my attention to it in the recent past..
It gives the spectral class as C5,4 and a V magnitude of 11.15
VizieR gives it a magnitude of +12.1.
And I am now of the opinion that VizieR is 100% correct.
There is a star called TYC 4014 2776 very close by whose mag. is +11.4; and Case 271 is much fainter than that.
I could only see Case 271 at a minimum magnification of 167X with the double star HJ 1930 in the same field of view.
However Case 271 was only very slightly orange to my eyes at magnifications up to 225X.
Therefore I do fully realise that this carbon star is not going to excite too many observers even here on the Observational Astrophysics forum.
But I am glad to say it is my 10th observed carbon star in Cassiopeia and my 87th overall.
