Brett's Carbon Star Hunt - May 2021
My observing time has been nothing since October or so, I think I am in an observing low, it happens. We'll see how things go.
I hope you all are able to get out and observe these - they really are nice stars.
T Lyr - (7.84 - 9.60) - I *believe* this is the first Carbon Star I observed when I was at the Observatory B&B in British Columbia a long while ago now - almost 7 years ago now.
Data can be found here, and observations can be found here.
T Dra - (7.2 - 13.5) - Data is found here, and the observation log can be found here.
TW Oph - (11.6 - 13.8) - This is the more difficult challenge of the month, dimmer than the other targets, hopefully everyone likes the challenge! Data found here and observation log here.
I hope everyone is able to get out and observe!
Scope: Apertura AD10 with Nexus II with 8192/716000 Step Encoders

Proxima is a Red Dwarf and not a Carbon Star - they are different types of stars.Piet Le Roux wrote: ↑Sat May 01, 2021 3:37 pm I think Proxima Centauri qualify as a red dwarf and carbon star ? please correct me if I am wrong. I have been trying to identify it but it is a dim 11 magnitude star among other similar stars.....I think I will give it another try....
