Brett's Carbon Star Hunt - December 2020
Once again due to "reasons" November was a complete washout - December will likely be the same but I will keep going.
I hope everyone else had a good November, and will have a better December!
As always, info on Carbon Stars can be found here.
On to our targets for this month!
BL ORI - There seems to be some discrepancies between the magnitude range for this one. Sky Safari lists it as 7.9 - 9.7, but the AAVSO Database says 5.9 - 6.6. Which is correct? I do not know. What will you see?
AAVSO Data.
And Reported Visual Observations for the last year: https://www.aavso.org/apps/webobs/resul ... tar=BL+Ori
W CMA - Data and Observations
T CNC - Sky Safari says this is a double star, so it should be a fun target. The Carbon is dimmer than the previous two this month - ranges from 7.6 - 10.5. The secondary, according to SS sits at 254 degrees, and is separated by 139"
Data and Observations
Good luck and happy hunting!

Thanks! I figured if people were looking for it, and found me they'd find it that way!Graeme1858 wrote: ↑Thu Dec 10, 2020 1:31 pm Judging by my signature weather forecast, I might get a go at this on Saturday night!

My weather looks like complete garbage for the near future. Tonight could be a possibility - but we have plans tonight, so it is basically out!
Someday. I hope it clears up the 21st though so I can get a peek at Saturn/Jupiter.
Good luck Graeme - I hope you are able to get out and check them out!

Re: Brett's Carbon Star Hunt - December 2020
Found BL Orionis and W Canis Majoris without a lot of difficulty. BL Orionis was easily located by visualizing a right triangle with Alhena and Alzirr in Gemini. W CMa a bit trickier. I made an imaginary triangle with Muliphein and Theta CMa. Could not locate the third challenge star. Maybe too dim for the little 80mm scope.
Anyway, it was a fun challenge and I thank you, Brett, for the targets.

Re: Brett's Carbon Star Hunt - December 2020
Moving on to T Cnc I set the sequence to capture 3 instances of 2 x L, 1 x R, 1 x G, 1 x B at 180 seconds each. But the clouds filled the sky before the sequence finished. So this is 4 x L, 2 x R, 2 x G, 2 x B. I had to make some copies so that I had a minimum of 3 per channel for
The images are not brilliant, they need more data and I didn't bother doing any Flat Frames but I got some imaging practice in, I got some processing practice in and I tested my new Sequence Template. However, the targets are excellent! The colours of Carbon stars are stunning. Would have liked to have got the double W Cma but the weather and the altitude decided otherwise.
Cheers Brett
