Brett's Carbon Star Hunt - January 2022

#1

Post by KingNothing13 »

Hi all - I apologize for the lateness of this list, as well as for missing December - things got out of hand, and time has been moving way to fast for my liking lately!

Anyway, here are 4 targets for this month, good luck and "keep looking up!"

All of the text descriptions come from SkySafari.

Some day, maybe I'll get to participate in my own program! :lol:



X CNC: 5.52 - 7.5

X Cancri is a 6th magnitude Variable Star appearing in the constellation Cancer. It is 1117 light years from our solar system. It is a red star of spectral type C5,4. Its energy output is 332 times the Sun's luminosity.

X Cancri is a pulsating semi-regular variable star of type SRB. Its magnitude varies from +5.5 to +7.5, over a period of 193.0 days.

Thank you for your fine targets this month Brett. I know what you mean about things getting away from you and having to push some things to the back of the queue! :)

I am going to try to find the Canis Minor one this eve. (Assuming it will be clear!!!) Thanks for posting these targets Brett. (Haven't been out in awhile). I'll be using the 6" achro which I have already hauled out to the back deck.
