Brett's CarbonStar Hunt - October 2021
I recently joined a local astronomy club which also has membership in the Astro League, so I picked up the AL Carbon Star Program booklet. While I have been using their list all along, it will give a little more info on the stars, etc. I also plan on, eventually, submitting for their program completion, etc. So we will see how that goes! I've already learned that not all Carbon Star's are red - this month's targets has a white one - every once in-a-while, I will throw a curve ball!
Anyway, on to the targets for this month!
HD 26 (SAO 109003) +8.2 - 8.3
Not a variable star, so nothing in the AAVSO.
From SkySafari: HD 26 is a 8th magnitude Star appearing in the constellation Pisces. It is 1091 light years from our solar system. It is a orange giant of spectral type G5:III:CH. Its surface temperature is 5050 Kelvins - 12% cooler than the Sun's - and it is 10.4 times the Sun's diameter in size. This star's total energy output, or luminosity, is 63 times the Sun's, and it has a mass of 1.1 Solar masses.
AL note: No apparent color - appears mostly white with a possible yellow tinge.
HD 223392 (SAO 128396) +8.5 - 8.8
Also not a variable.
From SkySafari: HD 223392 is a 8th magnitude Star appearing in the constellation Pisces. It is 843 light years from our solar system. It is a orange-red giant of spectral type C-R3- III C2 4 CH3.5. Its energy output is 27 times the Sun's luminosity.
AL Note: Light reddish-orange in color
CY Cyg +7.9 - 8.4
Data: https://www.aavso.org/vsx/index.php?vie ... &oid=11045
Observations: https://app.aavso.org/webobs/results/?s ... _types=vis
{There's one observation in there, from August 2019.}
From SkySafari:
CY Cygni is a 8th magnitude Variable Star appearing in the constellation Cygnus. It is 398 light years from our solar system. It is a red star of spectral type M2p. Its energy output is 5.8 times the Sun's luminosity.
AL Note: Yellowish-Orange in color.
Scope: Apertura AD10 with Nexus II with 8192/716000 Step Encoders

Re: Brett's CarbonStar Hunt - October 2021
We have clear skies forecast here for tonight. I'll get my sexy new binoculars out to see If I can spot these three.
Whilst my star chart book is still put away in the loft, I tried inverting a Stellarium screen dump to print for the September Challenge. But the print out was a tad poor! I'll take the laptop out with me for this one!
Regards

Re: Brett's CarbonStar Hunt - October 2021
56 Cyg, in the same view, is the left eye of the Pelican, so I had a look at him for a while!
Not hugely successful for spotting carbon stars but lots of fun looking!
Thanks Brett.

Re: Brett's CarbonStar Hunt - October 2021
Sitting close to Deneb, in the band of the milky way Cy Cyg was able to plate solve. But for some reason,
After catching a few videos of Jupiter, the 95% humidity brought an end to the proceedings. Not a great success on the Carbon Hunt Quest but lots of fun nonetheless! I'm going to put the 1600MM back in and have another go.
