Sketch of Comet C/2022 E3, its track in two hours time.

#1

Post by John Baars »


Ah, fortunately a bright evening on the sixth of February 2023. Quickly out with my new grabngo 102 mm f/5 Startravel. Seeing was good, transparency was a bit disappointing though. The Moon was just rising. A bit of a gray sky.

With the good seeing I decided to finish what I had left out last time: separate Alnitak properly. The telescope did that without blinking an eye. Then some finger exercises on Rigel, the Orion Nebula and the Eskimo Nebula. But I didn't come out for those. Of course, it was comet C/2022 E3 that got my full attention.

According to Stellarium, it was neatly located in Auriga between the triangle Almaaz, Haedus and Saclateni. Doesn't that tell you anything? That's the triangle of stars of magnitude 3 near Capella, visible with great ease in binoculars. Better known to me as the "three little goats" in Auriga. In the sketch visible as the three brightest stars. Almaaz at the top. The sketch gives the impression of the image in the 24 mm Panoptic at 20X.

Finding the comet therefore presented no problem, and was even in the viewfinder at once. At a magnification of 20X in the main scope, it was an adorable sight. The comet itself had a somewhat denser nucleus, easily mistaken for a faint star. The haze around it made everything clear. At 70X, of course, I lost sight of the triangle; the comet got a little bigger, but no further details visible. I still looked for C/2022 U2, nearby, but it was too faint to see visually with this aperture and the Moon above the horizon.

Then I went at my leisure to look for the beautiful images of the Seven Sisters and the Orion Nebula, at various magnifications and, among other things, to determine how deep I got that night. That was Magn. 11.7 near the Pleiades, the faint stars right next to Atlas and Pleione. Experimenting a bit with a new telescope....always fun.

At the end of the session, when my cold feet gave the "go in" command, I again briefly looked for the comet. To my surprise, it had now moved quite a bit, much more than I expected. The sketch gives an impression of it. First sketch gives the impression of 18.00hrs UTC, the second one two hours later. Satisfied, I went inside to finish the rough sketches.

Please click on the image for a better view.

Great reporting, John...and as usual amazing sketches. I've been tracking the comet when clear. Interesting to watch it moving along!

Hello John. A superb report from you using your new 102 mm f/5 Startravel telescope. A lot of nice objects including the M45 (The Pleiades) but the main course in your session was of course the Comet C/2022 E3. And again, you supplied great sketches which demonstrates the movement of the comet in just 2 hours. Thanks for your very nice report John and congratulations on receiving the TSS VROD Award today.
