It's great to read about quite a number of observed carbon stars here on the Observational Astrophysics Forum in recent days and nights.
Please keep them coming! Thank you.
Here is a report of the latest carbon star I observed which has the designation Case 270.
It is less than 30 arc minutes from another carbon star - WZ Cassiopeiae and is right next to SAO 35999 which in turn has a magnitude of +8.8.
My telescope is a William Optics 158 mm F/7 apochromatic refractor which is placed on a Berlebach Planet altazimuth mount.
I was observing in my Bortle 9 back garden as the temperatures went from 3 degrees to 0 degrees Celsius.
There was no wind at all thankfully.
I had been challenged by Steve Smith to observe Case 270 over on the Double Star Forum.
As he had drawn my attention to it, I soon noticed what a tough time I was going to have to actually see it.
You see, its magnitude is +12.8. I don't believe it varies at all.
According to Guide 9.1 DVD it has another designation which is 3UC-001081.
Simbad has other designations, but I won't mention them here as they are not well known.
The Right Ascension of Case 270 is 00 h 02 m 18.8"
The Declination is 59 degrees 58 minutes 07.54".
So it is firmly located in Cassiopeia.
Its spectral class is C4.
And at a magnification of 280X I could just about see Case 270.
My eyepiece is a William Optics Uwan 4 mm.
Its colour through my apo was orange at that power.
I could not see the star at 225X.
It is my 11th observed carbon star in Cassiopeia - and my 88th overall.
Therefore if any of you do seek out Case 270 you will most likely need a good aperture telescope and a very clear sky with no wind.
Thank you reading my report.
Comments, corrections, images and even sketches are most welcome.
Clear skies from Aubrey.
