Comet C/2023 A3 (Tsuchinshan–ATLAS)
The last several nights have been overcast and even some desperately needed rain, so no images of the comet. The comet and tail keep getting smaller and fainter. The estimated magnitude of the comet is now +9.0. It was +8.3 when last viewed on Monday. I am only showing images from the Stellina telescope since the Vespera telescopes are fitted with filters for viewing emission nebulae.
Deep Sky Objects
I’ve started a new set of multi-night emission nebula observations. The Singularity application only allows five multi-night observations on each instrument. The new targets will be the Dumbbell Nebula (M27), The Ghost of Cassiopeia Nebula (IC 59), the Fossil Footprint Nebula (NGC 1491, SH2-206), the Northern Trifid Nebula (NGC 1579), and the Christmas Tree Nebula (NGC 2264). The full moon is no longer a problem, however intermittent clouds keep interfering with the observations and prevented the last two targets. The Vespera Pro started M27 on a previous night.
