My First Astronomy Sketch: Jupiter and its moons

My first astronomy sketch: Jupiter and its moons

Last night, I only had a window of less than 2 hours to look for M13 but I still did not find it. Haze had started to form near the horizon and my next door neighbour decided to keep their porch lights on tonight creating a glow in my view. I gave up after 2 hours and set up my alarm to wake me up at 4:30 AM so that I can check out Jupiter and Mars.

Fast forward to 4:30 AM:

My first view of the gas giant through light haze made my jaw drop. Here I am looking at what Galileo first saw 400 years ago. I took the opportunity to line-up my telrad as well. At first, it was just a white disk waving like a flag with 2 moons to the right. After fine-tuning my focuser I noticed 2 faint lines above the equator. After 5 minutes, I noticed a fainter third line near the top pole, and another moon appeared closer to the planet but in a more southern orbital plane. There also appears to be a 4th moon but it seems too far to the left that it might be a star.

I tried to take a picture of it using my phone to no avail. So I quickly looked for a piece of paper and a pen and made a rough sketch of it (attached). This was a lot of fun and self-gratifying!

While I was there, I also looked at Mars, but it was just an unremarkable faint brown dot. The Orion nebula was just to the right so I scanned it but the moon was just too bright and the haze was too much.

Overall, this morning’s experience was an unforgettable one, and I have a sketch I will remember it by.
