Brett's Carbon Star Hunt - September 2021
On to this month's targets.
For those interested in Carbon Stars, more info can be found here: https://en.wikipedia.org/wiki/Carbon_star as well as here:
https://skyandtelescope.org/observing/o ... bon-stars/
HD 198269 8.22
Since this is not a variable star (And I learned something that not all Carbon Stars are variable), there is no info in the AAVSO databases for this one.
This is taken from SkySafari:
HD 198269 is a 8th magnitude Star appearing in the constellation Delphinus. It is 1173 light years from our solar system. It is a orange-red star of spectral type C-H2 C2 2 CH4. Its energy output is 56 times the Sun's luminosity.

Some nice choices. Hopefully I can get out to see more!

Re: Brett's Carbon Star Hunt - September 2021
I found Delphinus and sat taking those stars in for a while. Then with El Salib at 7 o'clock, HD 198269 should be centre of view. I was definitely looking in the right place with the pair of 6.5 mag stars just visible to the East and the three like an upside down Aries to the West. But there was nothing to be seen.
A good calibration exercise though. 6.8 magnitude HD197103 is about as dim as I could see with tonight's seeing and my binoculars.
