Lunar Eclipse

Well, central Texas was completely socked in with clouds last night. We saw fleeting glimpses of the event but nothing to write home about. I did manage to get the shot below through a brief clearing of the cloud activity, though. Taken with a Nikon D7000, 80mm refractor mounted on a Manfrotto camera tripod.

M8 Lagoon Nebula and M20 Trifid Nebula

Taken two nights ago, utilizing a new field flattener I purchased from Orion Telescopes. This image is the full frame image with no cropping, which shows a great flat image end-to-end.

The image quality is okay. I was shooting into the border area between dark sky and a big light dome. Some more data with better focus will improve this a fair bit.

Imaging scope: Astrotelescopes 80mm ED refractor
Imaging camera: Nikon D7000
Guiding scope: William Optics 66mm Petzval refractor
Guiding camera: Orion Star Shoot Autoguider
Mount: Celestron CGEM
Light Frames: 6*6 mins @ ISO1250
Dark frames: 3*6 mins
Processed in Deep Sky Stacker, GIMP, Neat Image and Snapseed.

More Perseids!

I carefully walked through the hundreds of shots I took two nights ago on my laptop, and it turns out I captured quite a few meteors. I was using a super-high ISO (3200) to get them, so the images are rather noisy despite being put through some noise reduction software. Still, you can clearly see the meteors here.

Last night, despite cloudiness and distant summer lightning, I looked for the Perseids with my kids for about 6 hours, from around 8:30PM to 2:30PM local time. It wasn't a spectacular meteor shower from my perspective, averaging maybe 5-10 per hour. The clouds moved away at around 10:30PM, but came back at 2:30PM. Flashes of lightning from the distance remained persistent throughout the night, lighting up most of the sky. I saw some decent fireballs and a fair few smaller, short burst meteors. I have seen better displays in the past, though.

Below is an image of one of the meteors that graced itself in front of my 10mm lens towards the latter stages of the evening. I have lots more photos but will need to check those to see if I caught anything else!

Hope you had a decent show wherever you were watching from.

Visual Night Out

The last couple of months have not been too conducive to stargazing for me.I went home to Australia for a while with the best intentions of doing some astro work, but the Melbourne weather had other plans, which included "hosting" an Antarctic polar vortex which brought heavy rain to the area for much of my visit. I caught a fleeting glimpse of the Southern Cross, but that was about it.

I took my 12" Lightbridge out for some visual observations this past Friday. The weather here in Texas was exceptionally warm, but the skies were clear and rather steady. I think I set the scope up, including perfecting collimation, in record time - well under 5 minutes!

Saturn looked amazing. It had been a long time since I have viewed it, and the planet tilt in relation to our position made for a great view. I could clearly see Encke's Division, and several moons. Quite a sight!!!

Other visual targets for the night included the Ring Nebula, the M4 globular in Antares, M13 in Hercules (absolutely stunning tonight!), the Lagoon and Triffid nebulas and the Sagittarius Star Cloud. I also spied the M51 Whirlpool Galaxy which, despite heavy light pollution, revealed the two central bulges of the interlocked galaxies.

Great night out!

Interviewed by Breakthru Radio about Amateur Astronomy!

I had the delightful pleasure of being interviewed about amateur astronomy by DJ Jess Goulart about amateur astronomy a couple of weeks ago, and it went to "air" yesterday! We discuss subjects like astronomical equipment, choosing when and where to observe, exoplanets, and the distances of deep space objects. If you want to listen to me, as well as some cool new tunes, click on the link below:
