It was getting late in the evening, almost 1:00 a.m., in my backyard on June 6th and I was ready to call it a night. But Saturn was peeking out from behind some houses, and I thought, “I already have all my filters set out, why not try them?”.
As I mentioned in the previous log about Jupiter, the seeing conditions sucked, with lots of haze in the sky. Jupiter looked like it was underwater at times. Anyway, it was what it was.
The Hyperion 36mm 2″ lens showed Saturn nice and bright, but no real division other than the main rings around the planet. The 25mm super Plossl showed things clear and bright, but as with the observing of Jupiter, a 15mm Plossl was too strong and anything with my Powermate giving me virtual 12.5 or 7.5 was way too strong. Again, my 17.3mm Delos was the Goldilocks of the night, with power just right. » Read the rest
I was set up in my backyard on June 6th, trying out various things, and started observing Jupiter around 11:00 p.m. I think. I’m still getting going with my new eyepieces and layouts, so observed with my 36mm Hyperion 2″ lens, a 25mm super plossl, a 17.3 mm Delos, and a 15mm plossl. Just for fun, I tried playing with the Powermate 2x magnifier with it too, but seeing was way too hazy to pull up anything good. FYI, for alignment, I did a simple three-star Sky Align for the night to get going, and ended up with Regulus, Antares and Denebola.
At super low power, the Hyperion 36mm showed Jupiter relatively clear, moons were easily identifiable. The 25mm super plossl showed me good definition in the bands. But I tried the 15mm plossl (by itself) and played with the Powermate 2x to give me a virtual 12.5mm and 7.5mm power options, all three were too much power for the seeing conditions. » Read the rest
Experimenting with my setup for taking pics through my scope with an iPhone XS Max, and my success of the night was Mare Crisium aka the Sea of Crises.
Adapting from Wikipedia:
A lunar mare NE of the Sea of Tranquility, it is about 556 km / 345 miles in diameter.
It has a very flat floor, with a ring of wrinkle ridges (dorsa) toward its outer boundaries.
The craterPicard is located just to the east of Yerkes (both at 8:00 on a clock dial), and northwest of Picard are the craters Peirce and Swift (at 10:00 on a clock dial).
Like most of the other maria on the Moon, Mare Crisium was named by Giovanni Riccioli, whose 1651 nomenclature system has become standardized.
The image was taken June 6, 2019, from Ottawa, Canada in my backyard using a Celestron NexStar 8SE, iPhone XS Max in NexYZ adapter, NightCap software, f/2.4 lens, ISO 15, 1/125s, single frame, modified in Windows Photos (flipped, straightened 8 degrees, vanilla filter for contrast, brightened). » Read the rest
As I mentioned in the last post, I am a fair-weather astronomer. So even though I want to do “more” this year for astronomy, back in January, I debated whether I could allow myself to skip the lunar eclipse, seriously considering avoiding setting up because it was just TOO DAMN COLD to be working with a metal tube for very long, not to mention freezing my hands, nose and feet. Or having my glasses continually fogging up. Meh. But in the end, I decided I would set up…I mean, I have to, if I want to consider myself an astronomer, right? But then it clouded over and I could pretend to be miffed while secretly being relieved. But if last year was any indication, I need to make a much greater effort to get out there and observe other than waiting just for our monthly Star Parties.
This year I have no real excuses not to be rocking my astro hobby, including some basic AP. » Read the rest
