Hello, all.

I have just been cleaning both my refractors after a short stint of observing Mars on Friday night 6th November 2020. The wind had died down completely after 9 pm and the temperatures had fallen to -1 degree Celsius as Valerie and I were figuring out what was on the Red Planet.
Earlier I had been having a great time observing from 5.15 to 6.15 pm some recent doubles which were new to me. The sky was pristine then when the temperatures were 4 degrees with a gentle breeze.

1. STF 3057 and STF 3062 are a stunning double - double. The former which is an uncertain double has magnitudes: A = 6.7. B = 9.3. Sep = 3.9". PA = 298 degrees. Both stars are white. The latter is a true double with magnitudes: A = 6.4. B = 7.3. Sep = 1.5". PA = 7 degrees. A is G3 yellow. I was able to place both doubles in magnifications 112X, 140X and 167X in the same FOV. Fabulous!

2. I also revisited the delightful KR 1 which is an uncertain double. Magnitudes: A = 9.4. B = 10. Sep = 2.1". PA = 192 degrees. Fine tight split at 112X and 140X.

3. And so I come to my 17th observed carbon star in Cassiopeia. Kiso C1-63 is relatively easy to find as it is quite close to Caph (Beta Cassiopeiae) and some other reasonably bright stars. There is a delightful and gentle curve of 3 stars and Kiso C1-63 is at the true north end. Its spectral class is simply C and its magnitude is +12.2. It does have 2 other designations which might prove fruitful to know: NSV 107 and GSC 04014-0296. The right Ascension is 00 hours 15 minutes and 53.67 seconds. The Declination is +60 degrees 53 minutes and 28.68 seconds. I found this carbon star at a mere 112X. But as I increased my magnifications up to 280X its orange colour became quite a bit more intense - but not too intense as MSB 75 proved to be which I did observe very recently. Kiso C1-63 is the first carbon star I have observed with that unusual designation. And I have found out what the abbreviation stands for: Kiso International Student Organisation. Kiso C1-63 is the 94th carbon star I have observed.

4. Lastly I came to Mars. At 112X I could see the very famous Syrtis Major. At 167X Mare Tyrrhenum was observed. At 225X the tiny South Polar Cap was plain to see. And at 280X I was seeing Mare Serpentis beginning to come into view. But at that final magnification Mars was a bit blurred some of the time.

Thank you for reading, one and all.
Comments, correction, sketches and even images are all very welcome!

Clear skies from Aubrey.

Yay - Another Carbon star! Congratulations Aubrey! The designation is a new one for me.  Kiso C1-63 sounds like a beautiful star, and I very much like how you have compared it to MSB 75.

Your report on Mars was excellent too. It is amazing to see the Martian landscape change before your very eyes!

Clear skies,
