STF 928, STT147 and a carbon star looking like burning red copper
On the 18th of March 2022 I aimed my telescope at Struve 928 in Aurigae. I cranked up the magnification to 83x, and I got a very pleasant surprise in my field of view. I got a split of the yellowish-white double STF928 with a separation of 3.5". In the same field of view to the south-east I saw another beautiful triple star, STT147. Thebright a-component looked deep yellow. But the real, unexpected showstopper for me was a star that looked like burning reddish copper. This proved to be the carbon star UU Aurigae. What a beauty! I am always amazed how beautiful these carbon stars are when seen visually through a telescope. UU AUR is of spectral type C6,3 and has a B-V index of about 3. Amazing beauty. On the sketch below, you see UU Aurigae as the bright orange-red stare on the right. The sketch was made ate the telescope on white paper with pencil. Later indoors the sketcht was digitalized in Affinity Pro. South is up an d east is to the right. The observation was made in a 150mm newtonian with a 9mm Morpheus eyepiece. Magnification is 83x and the field of view is 55'.
Last night was good... although the seeing was too bad for double stars, the transparency was perfect. Observed some globulars (M5, M10, M12, M13) and some beautiful carbon stars. T Lyrae was a gem as always. Here's a sketch of T Lyrae I made a few years ago with a 4 inch refractor, also from my backyard.
Tal 100 mm refractor f/10, Panoptic 35mm, magn. 28x. North is up, West is to the left.
